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...

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...

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...

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...

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...

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...

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...

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...

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...

The town of Namie, in eastern Japan, was devastated by the earthquake and tsunami of 2011, and has struggled to recover from the devastation of that day. Almost seven years later, the first new plant in town is set to open, one contributing to clean energy and zero-emission vehicles to boot...

The main impediment to mass electric-car adoption is price, and the driving force behind that is the cost of lithium-ion battery cells. The performance of those cells improves at about 7 percent a year, give or take: Either the same cell costs 7 percent less after a year, or a carmaker gets 7...

For a company that has only two battery-electric models in production, both several years old, VW Group spends a great deal of time talking about electric cars. The company has plans to launch 30 new electric vehicles by 2025, and has released four Volkswagen ID concepts, the first of which will...

The battery packs of most modern electric cars are far different than those in your mobile phone or other portable devices. In most cases, they include hundreds or thousands of cells, arranged into modules, and usually surrounded by channels containing liquid coolant to keep the battery in its...

Just a handful of companies today make the bulk of battery cells used in plug-in electric cars worldwide. Now the largest single maker of electric-vehicle cells in China has expanded its focus, from the home market to global markets and specifically the U.S. The name, CATL, may not be familiar to...

We tend to take batteries for granted. Day after day, we recharge batteries and expect them to work without giving a thought to how they work or to their state of health. But Akira Yoshino is different. He's one of the pioneers of lithium-ion battery technology. DON'T MISS: Lithium-ion battery...

While lithium-ion cells have powered all but a handful of plug-in electric cars since 2008, carmakers have looked further down the road toward solid-state battery cells with an eye toward launching them sometime during the 2020s. On Monday, BMW Group and Solid Power announced that the two companies...

The automotive business is one that turns raw materials into highly complex finished goods. When the prices of key commodities—especially raw materials—rise, everything downstream in that process becomes more expensive. That's Hyundai's concern over battery prices from 2020 onward, as...

For the 20 years since the introduction of the Prius, Toyota has enjoyed the first-mover advantage in hybrid cars, and leveraged those green credentials to boost public perception of its brand as a whole. But Toyota has yet to mass-market a battery-electric vehicle in the U.S., as Nissan has done...

Battery-pack prices are the lowest they've ever been, and like a yoga-obsessed limbo contestant, they're primed to go even lower. A report by Bloomberg New Energy Finance, based on a survey of "more than 50 companies," states the average cost of a electric-car battery pack is now $209 per...
