Fisker's promise to bring advanced, solid-state graphene cells to the battery pack of its upcoming Emotion electric car is officially dead. Automotive-grade graphene batteries have yet to be perfected, but Fisker was poised to become the first company to utilize the technology. The batteries...

VW Group remains one of the world's three largest carmakers, along with Toyota and General Motors, but the German automaker foresees challenges ahead. Specifically, Volkswagen believes the industry will face a shortage of lithium-ion batteries if new investment is not made soon for additional cell...

Studies have shown that electric vehicles have a number of strikes against them in the minds on consumers who don't know much about them. Range anxiety, the lack of electric vehicle charging infrastructure—or even awareness that it exists—and high purchase prices all play a part in the...

Henrik Fisker, the man behind the relaunch of the company that bears his name, has released some new details on the upcoming EMotion sedan. However, the news isn't necessarily the best that electric-car fans and advocates could have hoped for. The graphene battery technology Fisker has frequently...

With more plug-in electric vehicles on the road today than ever, automakers are working to solve an impending issue: what to do with used lithium-ion batteries. Once the batteries are no longer suitable to power vehicles, automakers must recycle or repurpose them. Now, through a partnership with...

Electric-car owners and advocates have a tenuous relationship with the franchised independent car dealers who are the only legal way to buy a new vehicle in the U.S. Tesla excepted, if you want to buy a new car, you have to go to a dealership over which the carmaker has only limited control. Horror...

As Tesla regularly points out, the lithium-ion battery cells used in electric cars can also serve in home energy-storage units. Now, a Daimler company will go up against Tesla in that field under the branding of its most famous luxury-car make. Mercedes-Benz Energy announced yesterday that it is...

It's one of the Holy Grails for battery researchers and electric-car advocates alike: a battery that could recharge in the same amount of time as it takes to stop for gasoline. Some of that can be provided by charging at higher rates, as Porsche's proposed 800-volt system for 15-minute fast...

Electric vehicles aren't always associated with speed and performance, but researchers at North Carolina State University may have discovered a breakthrough to change those qualities inside their batteries. Of all things, water may hold the key to faster electric-car battery technology. Researchers...

Perhaps the biggest question in buyers' minds over electric cars is how long the batteries will last. Most new-car buyers have mobile phones whose batteries have only lasted a couple of years, perhaps less. Even as electric-car battery packs are warranted against outright failure for eight or 10...

Seattle-based startup Zunum Aero has received funding from Boeing HorizonX and JetBlue Technology Ventures toward making its dream of electrified air travel a reality. Sometimes billed as the Tesla of the airplane industry, Zunum is developing a relatively small regional aircraft with about 700...

Tesla is currently ramping up lithium-ion battery cell production at its U.S. "Gigafactory" near Reno, Nevada. But the automaker has discussed plans for at least one additional Gigafactory, presumably to meet demand for battery cells related to large-scale electric-car production outside the U.S...

Lithium-ion battery-cell chemistry is currently dominant in electric cars, not to mention consumer electronics and other fields. But what seems to be an army of researchers thinks it can be improved. That includes one of the people who helped create lithium-ion batteries in the first place. CHECK...

For some buyers, where a car is made can be as important as the qualities of the car itself. "Made in America" can be a powerful selling point, especially after a presidential election in which domestic manufacturing jobs were a hot-button issue. But in the age of globalization, U.S. automakers no...

When it comes to Tesla and electric-car batteries, the eyes of most analysts are currently on the automaker's "Gigafactory," which began battery-cell production earlier this year. The Gigafactory is expected to build cells in massive numbers, but using a variation of the same lithium-ion chemistry...

Modern electric cars have developed to the point where range itself may become less of an issue than the cost of providing it. Automakers can create longer-range electric cars simply by installing larger battery packs, but that adds significant cost to the car's single priciest component. Just ask...

Long a leader in the push to reduce vehicle emissions and switch to renewable energy, California marks another milestone this week. The last of three battery energy-storage sites will come online in Southern California, providing storage and buffering for unpredictable renewable energy. Together...

The limitations of current lithium-ion battery-cell technology pose a hindrance to more widespread adoption of plug-in electric cars. Relatively short ranges and long charging times accorded by current lithium-ion cells still limit the appeal of electric cars in the minds of many new-car buyers...

High costs of lithium-ion battery cells have been one of the main hindrances to large-scale electric-car adoption, as they typically lead to higher purchase prices for electric cars than comparable internal-combustion models. But electric-car battery prices are falling fast, according to one recent...

Tesla is now producing lithium-ion battery cells at its massive Gigafactory.
