The current generation of lithium-ion battery materials is quickly approaching its theoretical limit. In commercial layered oxide cathodes, like the popular nickel-manganese-cobalt (NMC), there is only one lithium ion for every metal. So, the most energy you could possibly store with those materials is one full lithium in and out, or about 300 mAh per… Read more »

Dual-carbon battery claims to be longer-lasting and safer than Li-ion
Seldom does a week go by without an announcement of a promising new battery technology – but the road from the laboratory to the auto dealership is a long one, and there’s no knowing which of today’s breakthroughs might enable tomorrow’s mass-market EVs. This week’s news, from Power Japan Plus, almost sounds too good to… Read more »
Sporty prototype demonstrates flow cell battery technology
Among the many electrified vehicles on display at this week’s Geneva Auto Salon was one that demonstrates a new and possibly revolutionary energy storage system. Leichtenstein-based nanoFLOWCELL’s QUANT e-Sportlimousine, a sleek sports model with gull-wing doors, uses flow cell battery technology. Scientists at GE Global Research and Lawrence Berkeley National Laboratory announced that they were… Read more »
CalBattery’s new SiGr anode material hopes to break the battery bottleneck
California Lithium Battery took advantage of national and local government programs so it could focus on its revolutionary silicon-graphene anode material. Now with EV, electronics, and energy storage customers lining up, it hopes to break the battery bottleneck. When you think about a bottleneck, you think about constriction – something that moves in a particular… Read more »
University of Michigan and Ford open new battery lab
A new $8 million battery lab opened this week at the University of Michigan, the result of a collaboration between the university, Ford Motor Company, battery suppliers, and the state and federal governments. The lab is actually a battery manufacturing facility in which state-of-the-art methods will be used to make test batteries that replicate the… Read more »
Model S catches fire after collision
It was a horrible sight – a motionless Model S on a rain-slick Seattle road, its front half consumed in flames. No one was hurt, and the real flames were confined to a small section at the front of the vehicle. How far will the symbolic fire spread? It’s too early to say. If it… Read more »
Dual battery pack could give next-generation Tesla unprecedented range
Is Tesla working on a new type of hybrid pack that combines two different battery technologies to deliver a huge increase in range? This question has been floating around the discussion groups for a few months, but several outlets reported it as breaking news this week after a couple of stock analysts discovered the story… Read more »
BMW i3: The launch of many firsts
When you’re writing about the dawn of a new industry, “firsts” and “milestones” come along so often that they may start to lose their novelty. However, the BMW i3, which was officially “launched” in July, and is scheduled to go on sale next year, boasts an impressive number of innovations that has the EV press… Read more »
Plug In America research: Tesla Roadster battery longevity exceeds projections
By Tom Saxton, Chief Science Officer, Plug In America Many current and prospective electric vehicle owners are curious to better understand battery pack longevity. There’s plenty of technical data on how batteries lose capacity with use, but a lot of that testing subjects the batteries to extreme and rapid charge/discharge cycles, very unlike the much gentler use… Read more »
