Solid-state batteries sometimes sound a bit like the missing link that would punt electric vehicles soundly into mainstream acceptance. The list of potential virtues for solid-state tech, which would replace the polymer/gel electrolyte commonly used in lithium-ion cells with a solid one, is impressive: a longer driving range; smaller packaging;... VW confirms it’s planning for solid-state batteries by 2025
Solid-state batteries sometimes sound a bit like the missing link that would punt electric vehicles soundly into mainstream acceptance. The list of potential virtues for solid-state tech, which would replace the polymer/gel electrolyte commonly used in lithium-ion cells with a solid one, is impressive: a longer driving range; smaller packaging;... 
European electric-carmaker Renault plans to build the continent's largest stationary battery storage network next year using old electric-car batteries. Renault announced on Tuesday that it will install used (and some new) electric car batteries in three locations: two Renault factories in France, and the site of a former coal-fired power plant in... 
Reduce, reuse, recycle. It's the same philosophy for electric-car batteries as for plastic grocery bags—almost. Knowing what happens to lithium-ion batteries from phones, cameras, and other electronic devices, many electric-car critics express a reasonable concern about what might happen to the similar batteries on a much larger scale that... 
Researchers at the University of Maryland, in conjunction with Brookhaven National Laboratory have developed a new battery cathode material that they say could triple the energy density of lithium-ion batteries. The new material is an engineered variety of iron trifluoride, a well-known material that has had problems with rechargeability and low... 
Utilities are racing to expand battery storage on the electrical grid. The latest example is Pacific Gas and Electric Co., which submitted a request Friday to the California Public Utilities Commission to build and install four large banks of lithium-ion battery storage, according to the San Francisco Chronicle. The projects would include Tesla's... 
Falling prices for lithium-ion batteries will enable half the world's electricity to come from renewable solar and wind by 2050. That still won't be enough to meet global climate targets, however. Those are the conclusions of a new report by Bloomberg New Energy Finance (BNEF), released today. Building on BNEF's Electrc Vehicle Outlook report last... 
Facing competition from American scientists, Japanese automakers are teaming up to develop solid-state lithium-ion batteries for electric cars, according to a Nikkei report. Some engineers see solid state batteries as the holy grail for cars because they are safer and have higher energy density than today's lithium-ion batteries. That can give... 
It's every electric car owner's nightmare: the car indicates that remaining range has suddenly plummeted to zero, the battery pack stops providing current, and the car won't run. For some 2017 Chevrolet Bolt EV drivers, that scenario has happened in real life. The problem has resulted in a program under which Chevy will replace the entire battery... 
With more than 300,000 Nissan Leaf electric cars on the road, some more than six years old, battery degradation is becoming more and more of an issue. The different rates of capacity loss are a topic of much discussion among Leaf owners, but it now seems likely that Nissan's choice of passive air cooling rather than active liquid cooling has... 
The Nissan Leaf, at least for the moment, remains the highest-volume electric car produced in history, with more than 300,000 sold. One of the measures that kept its cost down was the use of passive air cooling for its battery pack, rather than the pricier liquid cooling used by other makers to keep battery temperatures within limits. Nissan has...
