In the ever-evolving world of battery technology, the safety of lithium-ion (Li-ion) batteries has become a paramount concern, especially as the demand for electric vehicles (EVs) and renewable energy storage systems surges globally. Epsilon Advanced Materials (EAM), a leader in the production of high-quality battery materials, is at the forefront of addressing these safety challenges. Through innovative solutions and a deep commitment to sustainability, EAM is enhancing the performance of lithium-ion batteries and significantly reducing risks associated with their use.
EAM’s journey is rooted in a vision of decarbonizing economies and driving the transition to cleaner energy technologies. It all began when an entrepreneur with a passion for sustainability crossed paths with a battery engineering scientist who had developed an exceptional battery material in his backyard. This meeting of minds sparked the creation in 2018 of EAM, a company dedicated to perfecting the art and science of advanced battery materials. Since its inception, EAM has sought to lead the way in providing innovative battery solutions that meet the demands of a rapidly changing world.
EAM’s approach to battery safety is through its focus on synthetic graphite anode materials. These materials are designed to improve fast charging performance, a feature that is increasingly important as consumers demand quicker charging times for their EVs. Traditional battery materials can struggle to handle the higher currents involved in fast charging, leading to stress on the battery and an increased risk of overheating. However, EAM’s synthetic graphite anode material is engineered to handle these higher currents with less stress, significantly reducing the risk of overheating and enhancing the overall safety of the battery.
Another key factor in the safety of Li-ion batteries is the direct current internal resistance (DCIR), which represents the resistance to current flow within the battery. Higher resistance can generate heat, which in turn increases the risk of thermal runaway – a dangerous situation where the battery can overheat uncontrollably. EAM’s synthetic graphite-based anode material boasts lower DCIR, meaning it offers less resistance to current flow. This reduction in resistance provides better heat management within the battery, minimizing the chances of thermal runaway and ensuring safer operation even under high-stress conditions.
In addition to these advancements, EAM’s synthetic graphite anode material also offers superior cycling stability compared with natural graphite. Over time, battery materials can degrade, leading to unwanted reactions within the battery that can generate heat and compromise safety. EAM’s material, however, degrades less over time, maintaining its stability and reducing the likelihood of these unwanted reactions. This enhanced cycling stability not only extends the lifespan of the battery but also ensures that it operates safely throughout its life cycle.
EAM’s commitment to safety and innovation is further demonstrated by its plans to open a state-of-the-art battery materials and components plant in North Carolina in 2026. This $650-million facility will be a significant step forward in the domestic production of battery materials, including both natural and synthetic graphite anodes. With a targeted annual production capacity of 60,000 tons of anode materials by 2031, the plant could eventually supply enough materials for up to 1.1 million electric vehicles in the U.S.
The decision to establish this manufacturing plant in Brunswick County, NC is strategic, as this location will be part of a burgeoning EV battery hub in the state, positioning EAM to play a critical role in the U.S. battery supply chain. This move is particularly timely given recent developments in the global graphite market. China, which dominates synthetic graphite production, has recently curbed exports of the material, leading to concerns about supply chain stability and rising costs. By developing a domestic source for synthetic graphite, EAM is not only reducing reliance on imported Chinese materials but also bolstering the U.S. battery industry against potential supply disruptions.
EAM’s U.S.-made battery components and materials are expected to qualify for incentives under the Inflation Reduction Act and related U.S. legislation aimed at building domestic supply chains for EVs and batteries. This support from the U.S. government underscores the importance of EAM’s work in ensuring that the next generation of batteries is not only high-performing but also safe and sustainable.
As EAM continues to innovate and expand, its focus remains firmly on the safety and sustainability of Li-ion batteries. The company’s advanced materials and cutting-edge technologies are setting new standards for battery safety, ensuring that as the world shifts towards cleaner energy and electric mobility, the batteries powering this transition are as safe as they are efficient. EAM is not just meeting the challenges of today’s battery industry but is also anticipating and addressing the needs of tomorrow. Through its commitment to innovation, safety, and sustainability, EAM is playing a key role in shaping the future of energy storage and electric mobility.

Today’s developments surrounding EVs are not a surprise. They were predictable, an awakening of sorts, to the realities of personal mobility needs and the true desires of a driving public amid a significant and sustained push toward electrification.
Unsold inventories of battery EVs at dealer lots, significant price cuts to move metal, and a rethinking of strategies are just part of today’s electric vehicle universe. We are seeing this new reality across the automotive spectrum as companies previously committed to being “all-in” for EVs – from Ford and GM to Volkswagen and Volvo – reassess the way forward.
Yes, interest in battery electric vehicles has grown substantially in recent years. EV sales have captured a larger slice of the new car market than might have been imagined in just the recent past and that percentage has been growing faster than before. This should rightfully be celebrated by EV enthusiasts. An impressive expansion of the zero-emission EV market should also be celebrated because of the considerable impact this has on decreasing carbon emissions, though it’s becoming increasingly clear that the hoped-for wholesale move toward battery EVs will not resolve our carbon challenges.
After more than three decades of documenting the commercialization of electric vehicles, I feel compelled to point out that EVs still represent a fraction of the overall automotive market and there remains great interest in more familiar options. Battery electric vehicles simply do not meet everyone's needs at this time. Barring significant breakthroughs in technology, cost, and convenience – the latter bolstered by an expansive and reliable national charging network and a resilient electrical grid to support it – there’s a possibility they may not meet all motorists’ needs for some years in the future. To our collective detriment, that has not stopped the powers-that-be from forcing an EV-first agenda.
The assumption that government can severely restrict consumer vehicle choices without alienating huge numbers of car buyers, creating financial havoc and uncertainties within the auto industry, and bringing an array of unintended consequences in coming years is simply an act of hubris. I've witnessed other examples of this over the years. Ultimately, the outcomes have not favored those in power who overstep and assume they know more about the needs and desires of car buyers than buyers themselves.
There are many reasons for this, but fundamentally let’s remember that a motor vehicle – beyond serving as a social conveyance for projecting image, status, values, or nuances of all sorts – is a crucial tool to get folks safely and reliably to work, school, the market, or wherever they need to be, regardless of distance or driving conditions. And lest we forget, a new car typically represents the second largest consumer purchase after a home. That makes buying a car an important financial decision beyond just being a very personal choice.
The battery EV’s rather eye-opening depreciation, identified by car search engine and research firm iSeeCars as averaging 49.1 percent over the first five years, isn’t very comforting from the standpoint of a financial strategy. It’s worth noting that iSeeCars doesn't see this same kind of depreciation across the board for electrification, identifying hybrids as having a nearly 12 percentage point advantage over EVs in value retention over a five year period, slightly better than the depreciation rate for all types of cars.
How much has changed for electric cars over the years? A lot…and too little. To share some perspective, I’d like to offer up a Green Car Journal editorial I wrote in 2012, Curb Your (EV) Enthusiasm. It seems prescient today. In it, a dozen years ago, I pointed out that:
– After decades of battery development, the expectation that battery breakthroughs would come to make EVs cost competitive with internal combustion vehicles had not materialized.
– Battery electric cars still required significant federal subsidies to encourage sales because of their high battery cost and retail price.
– In a normal world, a compact electric SUV should not cost $50,000, a four-door electric sedan $40,000, or a small electric hatchback over $30,000.
– A small number of electric vehicles might be available under $30,000, but comparable internal combustion models would typically be priced many thousands of dollars less while offering greater functionality.
– Government agencies viewed EVs as a panacea for decreasing CO2 emissions, improving air pollution, and enhancing energy security.
- States embraced electric vehicles in their State Implementation Plans as a strategy for showing how they would meet air quality standards mandated by the Clean Air Act.
– Automakers recognized electric propulsion as a strategy for meeting increasingly higher fleet fuel economy targets.
– Electric utilities viewed EVs as a pathway to selling electricity as a motor fuel.
The conclusion about the way forward a dozen years ago? Battery electric vehicles are one part of the solution along with advanced combustion vehicles, hybrids, plug-in hybrids, and extended-range electric vehicles that create on-board electricity to provide full functionality.
It appears there’s a growing consensus today that we’ve come full circle to this way of thinking. As electric vehicle sales cool, multiple automakers have shared they are backing off from previously-announced timelines for EV model introductions, new EV assembly lines, and greenfield battery plants. There’s also a new emphasis on producing an expanding lineup of hybrid and plug-in hybrid models that consumers increasingly desire, even on the part of major automakers that have previously announced plans to exclusively build battery electric vehicles and have shown little interest in hybrid power.
All this underscores that as much as we’re enamored with modern battery electric vehicles and their ability to address carbon emissions, they are not the singular answer to future mobility. They are a choice among other vehicles and technologies that also speak to individual needs, desires, and environmental sensibilities. And that’s the way it should be.
We’ve spent hundreds of thousands of miles behind the wheel of a great many electric vehicles, hybrids, and plug-in hybrid models over the years. They all have their advantages and appeal…and each speaks to the very specific needs of different types of drivers and their daily rhythms. If you’re inclined to go electric as a way of addressing efficiency and environmental concerns – but hesitant to rely exclusively on battery power for reasons compelling to you and your situation – then you’re an excellent candidate for a plug-in hybrid.
Beyond its advanced technology and user friendliness, there’s an elegant beauty inherent in a PHEV. Within the capabilities of its battery powered range, a plug-in hybrid allows driving on electric power, internal combustion power, or a combination of the two. You are effectively in an electric vehicle with options and the transition from electrons to gas is essentially seamless.
Plug-in hybrids present a logical choice because they present no limitations. These days, chief among these limitations with battery electric vehicles is range anxiety, whether imagined or real. When driving an electric vehicle, remaining battery power is always top of mind to ensure there’s adequate on board energy to get you to where you need to be. This is less of an issue today with popular electric models offering much longer range in the many hundreds of miles, but the concern persists.
Not so with plug-in hybrids. With PHEVs, you get the benefits of an electric vehicle while driving on batteries like zero emissions, near-silent operation, and improved performance. When battery energy in a PHEV is depleted you keep on going with combustion or hybrid power as long as there’s gas in the tank.
Like hybrids, plug-in hybrids take several forms. The most common of these is the parallel plug-in hybrid, which uses an internal combustion engine and one or more battery powered electric motors to directly drive the wheels. A series plug-in hybrid, also known as an extended range electric vehicle (EREV), delivers power to the wheels through its electric motor, or motors, with the combustion engine and batteries providing electricity to power the motors. In this configuration the engine operates exclusively as a generator with no mechanical connection to the road. An example of this is Karma’s GS-6. Some models, like the Toyota Prius Prime and Mitsubishi Outlander PHEV, are series-parallel hybrids that use both power strategies for motive power, along with the zero-emission electric driving for which plug-in hybrids are known.
Both plug-in hybrids and conventional gas-electric hybrids achieve their higher efficiency through an intricate computer-controlled dance that blends electric and combustion power in response to real-time driving conditions. While each benefits from the efficiencies that gas-electric hybrid power delivers, at best a hybrid may drive exclusively on battery power for very short distances with a light touch on the accelerator pedal.
Plug-in hybrids are different. They’re equipped with larger battery packs than hybrids, though these packs are still quite smaller than full electric vehicles. These larger batteries, and the ability to plug in and charge up, allows a PHEV to drive greater distances on battery power alone. The Volvo S60 T8 Recharge plug-in hybrid sedan, for example, features 40 miles of electric driving and an overall 530 mile range, while the Kia Sportage PHEV delivers 34 miles on battery power with a total 430 mile driving range.
Determining your needs is an important step in deciding whether a plug-in hybrid is the right choice. For example, if your daily drives average 30 miles or so, then either of the above examples – and quite a few other PHEV models – will allow driving electric without the need for hybrid power to kick in. Just charge your PHEV’s battery overnight and you’re ready to go again the next day, with no need for a trip to the gas station. Even plug-in models with shorter electric driving range will still do for your commute if there’s charging available at your workplace, since a workplace charge opportunity can effectively double a PHEV's round-trip battery electric range.
Here’s the underlying advantage of a plug-in hybrid vehicle: If you do need to drive farther than a PHEV’s electric range, then you’ll take advantage of the zero-emission efficiencies of battery power with gas-electric hybrid drive handling the rest of your miles. The same holds true for those longer drives, such as visits with far-away friends or longer vacations and road trips. Easy.
So is a plug-in hybrid right for you? It’s a personal decision based on preferences and the degree to which you want to go electric. For those who want to ease into an electric future without limitations, then a plug-in hybrid may well be the best choice for you.
There’s an all-new Dodge Charger Daytona hitting the streets of America. This storied name channels echoes of of the past with the mind’s eye visualizing the rare, wildly-winged 1969 Dodge Charger Daytona of the muscle car era, a model that raced in NASCAR and was available only in small numbers to well-monied car enthusiasts. While the 2024 Charger Daytona is a bit more civilized than its namesake of 55 years ago, it is equally dramatic in its own way.
Back in the day, muscle cars were a dominating force on dragstrips and, more importantly, on the highways of America. These go-fast models delivered the whole package for car enthusiasts – exciting looks with stripes, scoops, and a stance with attitude, their mere presence tantalizing the senses with a low engine rumble at idle, a throaty roar at speed, and if you were the one behind the wheel, an adrenaline rush like no other.
They also sucked gas on an epic scale with their four-barrel, six-pack, and sometimes dual-quad carburetors. High horsepower small- and big-block engines were high-compression to eke the most power from the air-fuel mixture fed to combustion chambers, which meant more expensive high-octane premium fuel. Muscle cars, and really most cars of the era, had tailpipe emissions that were nothing to brag about. Still, these were iconic hot rods that defined an era.
While the performance-infused Daytona designation has been used sporadically by Dodge since, this is different. Stellantis has read the tea leaves well and the all-new Dodge Charger is not only fast and formidable, but also headlined by two fully electric variants, the Daytona R/T and Daytona Scat Pack. This move ensures the Charger’s claim as the world’s quickest muscle car, and the most powerful.
That doesn’t mean the automaker has abandoned the high horsepower gas engines that have powered this model over the years. Car enthusiasts who wish that familiar experience can opt for the Charger SIXPACK 3.0-liter twin turbo Hurricane engine in either Standard Output or High Output versions.
Specs for the electric Charger Daytona models surpass those of the gas versions, with the electric Daytona R/T besting the SIXPACK S.O. with 496 horsepower vs. the gas version’s 420. The Daytona Scat Pack does even better by delivering an electrified 670 horsepower vs. the gas high output engine’s 550, a bump of 120 ponies overall. The Daytona R/T is expected to deliver 317 miles of driving range with the more powerful Scat Pack a shorter, but still substantial, 260 miles.
Acceleration is impressive, with the Daytona Scat Pack expected to close a 0-60 mph sprint in just 3.3 seconds while earning a quarter-mile elapsed time of 11.5 seconds. Performance is enhanced in Daytona models with a PowerShot feature that provides an additional 40 horsepower boost for up to 15 seconds when needed. Stopping power is bolstered with 16-inch Brembo vented rotors and distinctive red six-piston calipers up front and eight-piston calipers at the rear. All Charger models are four-wheel drive. Driver-selectable Auto, Eco, Sport, and Wet/Snow drive modes allow tailoring the driving experience, with the Scat Pack adding Track and Drag modes for good measure.
Serene silence is not the hallmark of the new Daytona as it is in other electrics. Rather, Daytona R/T and Scat Pack sound the part of earth-pounding muscle cars with their all-new Fratzonic Chambered Exhaust that replicates a Dodge Hellcat exhaust profile, with sound intensity tied to performance. Drivers can alternatively select a ‘stealth’ sound mode if that’s more to their liking…but what’s the fun in that?
All this power and performance would be academic if not packaged in an athletic form, and the new Dodge Charger does pull that off with a pure uninhibited muscle car presence. Its lines are sharp, evolved, and definitively true to the breed, featuring an appealing profile and a powerful widebody stance. This muscle car’s appealing ‘hidden hatch’ design is accentuated by a black painted flowing roofline that can be made more dramatic with an optionally available full-length glass roof. We particularly like that the front end is not closed off in a snout like so many electric cars, but rather features stylishly understated openings above and below the bumper fascia.
Inside is a driver-centric cabin featuring an instrument cluster with either a 10.25- or optional 16-inch screen, along with a center 12.3-inch touch screen angled toward the driver. A forward-looking flat top/flat bottom steering wheel design features an array of controls for popular functions and also includes paddle shifters for rapidly adjusting regenerative braking settings on the fly. The center console features a pistol-grip shifter and start button. Standard seating is cloth and vinyl with either black or red Nappa leather available as an upgrade. Rear seats can be folded flat for additional cargo capacity. As expected, a full suite of advanced safety and driver assist systems are standard or available.
Two-door coupe versions of the 2024 Charger Daytona R/T and Scat Pack feature an MSRP of $59,595 and $73,190, respectively, and begin production this summer. Four-door variants of the electric models will start production in the first half of 2025 with two- and four-door gas Charger SIXPACK models coming later that year. Pricing for these will be disclosed closer to their release.
Green Car Journal editor/publisher Ron Cogan was editor of Hot Rod’s Musclecar Classics in the mid-1980s.
Green Car Journal has closely followed the evolution of the Toyota Prius since our early hands-on experience at Toyota’s Arizona Proving Grounds in mid-1997. Here, we piloted a Toyota Corona test mule powered by an exotic gas-electric powerplant concept that was unlike anything we had driven before. Little did we know that this test car’s Toyota Hybrid System would make its way in production form to the automaker’s all-new Prius, a model that debuted later that year at COP 3, the third United Nations climate conference. This is where the landmark Kyoto Protocol international treaty was adopted to mitigate greenhouse gases and climate change.
The Prius was there to make a statement that Toyota recognized the environmental challenges ahead and was prepared to lead. Prius sales began in Japan in 1997 and expanded worldwide in 2000. The rest is history. In the 27 years since the Prius was introduced, this hybrid has stayed true to its original mission as a model of high efficiency and low carbon emissions. It has shape-shifted over time, starting out as a quirky subcompact sedan and then morphing into a hatchback with a distinctive and easily-recognizable profile.
Now in its all-new fifth generation, Toyota’s Prius is a true game changer presenting as a wondrous liftback with a whole new outlook that far transcends eco consciousness, though that is still the core of its being. Today’s Prius is now sleek and visually compelling, extraordinarily fuel efficient at up to 57 combined mpg, and delivers surprising levels of performance for an eco-champion priced at just $27,950.
For an additional five grand the model’s plug-in hybrid variant, Prius Prime, features all this along with a more powerful 13 kWh lithium-ion battery that brings an EPA estimated 45 miles of electric driving and up to 600 miles of overall range. Along with its admirable EPA estimated 52 combined mpg as a hybrid, Prime achieves up to 127 MPGe when running on its batteries.
Prius Prime’s considerable battery electric range makes it the ideal electric vehicle for a great many who wish to drive zero emission every day, but also want the ability to tackle longer trips seamlessly. This characteristic, and so many others that elevate the model above its peers, distinguished Toyota’s Prius Prime as Green Car Journal’s 2024 Green Car of the Year®.
Performance in a traditional sense, like quick acceleration and impressive driving dynamics, has never been expected of a Prius. That wasn’t its mission. This changes in a big way with the new Prius presenting as a driver’s car, a model that speaks to car enthusiasts who value appealing style and a fun-to-drive nature alongside environmental performance. The new Prius Prime’s 220 system horsepower, delivered by a 2.0-liter engine and 161 hp electric motor-generator, changes the performance equation with nearly 100 more horsepower and a third greater torque than the previous generation Prime. That extra power is a big deal and drivers will appreciate Prius Prime’s surprising ability to sprint from 0-60 mph in just 6.6 seconds.
Greater performance aside, the most noticeable change in the new Prius is clearly its attention-grabbing, smoothly sculpted design. We know this first-hand. Over the past few months, we’ve spent significant time behind the wheel of an uplevel ($39,670) Prius Prime XSE long-term test vehicle equipped with this model’s full complement of advanced electronics and a cabin smartly upholstered in leatherlike SofTex. Inevitably, we get looks, questions, and overt signs of appreciation from a great diversity of people during our drives, many of them drivers of earlier Prius models and others who simply love the car’s forward-leaning and distinctive look.
We get it. The new Prius exudes a sporty appearance with its low roofline and sweeping aerodynamic profile, lending homage to the Prius of old while transforming its look into something more compelling. Once attention moves beyond the car’s most noticeable and eye-catching feature, there’s plenty inside to appreciate as well. Here, one finds a comfortable and functional cabin featuring a pleasing balance of tech, comfort, and style, with a distinctive instrument panel design that takes its cues from Toyota’s bZ4X electric car.
We’ll be sharing our experiences of daily life with the Prius Prime in the months ahead, and no doubt, more stories of interactions with others who find the all-new Prius as compelling as we do.
Manufactured in Tennessee on Volkswagen’s MEB modular world electric car platform, the 2021 VW ID.4 presents a new and compelling all-electric SUV that enters a segment presently dominated by Tesla, Chevrolet, and a select few others. What ID.4 brings to the battery electric SUV segment that Tesla doesn’t is price, coming in at a base cost of $39,995, some $10,000 less than Tesla’s Model Y.
For this, electric vehicle buyers get SUV hatchback utility, three-foot legroom in all seating positions, and ample luggage capacity for 5 adults. VW estimates ID.4 driving range at 250 mile on a full charge, and additionally points out that an additional 60 miles of range is attainable in just 10 minutes from a public DC quick-charge station.
Sporting a stature similar to that of Honda’s CR-V, the Volkswagen ID.4 rides on a steel-framed architecture featuring strut-like front suspension and multi-link suspension with coil-over shocks at the rear. This, combined with a long wheelbase and short overhangs, promises a smooth ride dynamic. Braking is handled by front disk and rear drum brakes.
A single permanent magnet, synchronous electric motor directs power to the rear wheels. The ID.4 produces 201 horsepower and 228 lb-ft torque that’s expected to deliver a 60 mph sprint in about 8 seconds. Electricity to power the motor is provided by an air-cooled, frame-integrated 82 KWh lithium-ion modular cell battery. An onboard 11KW charger enables three charge modes via standard 110-volt household power, 220-volt Level 2 charging, or DC fast charging. Typical charging with a home wall charger or public Level 2 charger will bring a full charge in 6 to 7 hours.
A minimalistic yet futuresque cabin with segment leading cabin volume rounds out ID.4’s architecture. Features include a driver-centric, touch sensitive steering wheel and a view-forward 5.3-inch ID information center that replaces conventional gauges. Vehicle operation is through steering wheel-mounted switches, with infotainment, climate control, device connectivity, navigation, and travel information accessed through a 10.3 inch touchscreen monitor. A 12 inch monitor is available with the model’s Statement Package.
Topping the list of features is expanded voice command and a communicative dash-integrated ID light bar. ‘Intuitive Start’ driver key fob recognition enables pre-start cabin conditioning capability. Base model upholstery is ballistic cloth with leatherette seat surfaces optional.
Volkswagen’s IQ Drive driver assist and active safety suite features travel assist, lane assist, adaptive cruise control, front and rear sensors, emergency assist, blinds spot monitoring, rear traffic watch and more. All this comes standard along with Pro Navigation, a heated steering wheel and front seats, wireless phone charging, and app connectivity for compatible devices.
The ID.4 EV is available in six colors and two trim levels, Gradient and Statement, for personalization. The optional Gradient package features a black roof, silver roof trim, silver accents, and silver roof rails along with 20-inch wheels to complete the upscale look. Looking forward, while rear-wheel drive is the choice today, Volkswagen is already talking up an all-wheel drive variant for early 2021 along with a lower-priced base model.
As the world’s largest automotive group, Volkswagen has the capacity to change the ever-expanding electric-car landscape. Looking at the style and utility of VW’s all-new ID.4, you can sense the renewed “people’s car” direction of the brand that accompanies the automaker’s commitment to electrification. VW says it’s aiming at selling 20 million electric cars based on the MEB electric car platform by model year 2029. Certainly, the potential for selling in truly significant numbers is reinforced by ID.4 pre-orders selling-out in just weeks, it’s safe to say.
