Electric car battery research pact seeks to keep German auto prowess

VW Battery PacksFor the past 50 years, the German auto industry has enjoyed quite the roll of growth and success in the U.S., built largely on its expertise with one specific technology: the internal combustion engine. But now the importance of that advantage is fading, with electric cars on the rise and the highest-value component within them the battery pack...

Volvo reuses bus batteries for solar storage

Riksbyggen Viva co-op housing complex, Gothenberg Sweden [Credit: Riksbyggen, Creative Commons] As solar installations ramp up and electric vehicles have been on the market for a few years, automakers are starting to look for ways to get more life out of old electric-car batteries, repurposing them for stationary storage. And if you're going to use vehicle old batteries for storage, you might as well use big ones. Volvo, which builds trucks...

VW confirms it’s planning for solid-state batteries by 2025

Thomas UlbrichSolid-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;...

Quantum computers could make specialized batteries for Volkswagen EVs

VW to use quantum computers in electric-car battery developmentQuantum computers could analyze and help build highly specialized electric vehicle batteries in the future, Volkswagen announced this week. Using the highly complex computing tech, researchers simulated industrially relevant molecules in EV batteries that could help shape the next generation of compounds for use in green cars. Researchers said...

Nissan Leaf refurbished batteries offered for older electric cars, in Japan

2013 Nissan Leaf, Nashville area test drive, April 2013With 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...

Nissan, Sumitomo open electric-car battery recycling plant in Japan

Nissan electric-car batteryThe 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. Carmaker Nissan and an arm of the giant trading company...

Silicon anodes to boost lithium-ion battery capacity within a few years

Prototype production of battery modules for BMW Group’s fifth-generation electric powertrainThe 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 percent more energy capacity for the same price. Those...
