Study: The future of electric vehicles could ride on lithium-air batteries

Judging by the table shown above, lithium-air (Li/O2) batteries appear to be quite remarkable, on paper at least. But what can we really expect from this new advanced battery technology? Well Argonne National Laboratory has started researching and testing lithium-air batteries in earnest and presents a strong case that the future of electric vehicles may very well ride on this technology. If initial research turns out to be accurate, lithium-air batteries could hold up to ten times more energy t

Hitachi develops new manganese cathode, could double life of li-ion batteries

Battery breakthroughs seem to pop up almost every day. There's always a new idea, different material or unique design that makes the battery better. Some manufacturers make outlandish claims that can't be true while other companies string us out for years awaiting amazing products

Panasonic delivers first 3.1Ah lithium ion cells to Tesla

Tesla Motors has never officially announced who supplies the lithium ion cells used in the Roadster's battery pack, but it does have an agreement with Panasonic to supply cells for the Model S. Chief Technology Officer JB Straubel was in Japan this week and received the first batch of new lithium ion cells from Panasonic Energy Company President Naoto Noguchi.

Breaking: Denise Gray leaving General Motors for battery startup

Since late 2006, Denise Gray has been the director of global battery systems engineering at General Motors and one of the key people working to bring the Chevrolet Volt to fruition.

DC 2010: NAS' li-ion battery cost predictions are too high, battery makers say

During one of the sessions at the Electric Drive Transportation Association meeting here alongside the Washington Auto Show, our friend Felix Kramer from CalCars got an answer to a question that's been on his mind for a while: just how much wil

Michigan-based Sakti3 readying advanced batteries for cars

Michigan is quickly becoming a center of lithium ion battery manufacturing in the United States. Funny thing is, almost none of the companies setting up factories in the state are based there. Sakti3 Inc. wants a piece of that battery pie and it was formed right here in Ann Arbor. Sakti3 is the brainchild of Professor Ann Marie Sastry of the University of Michigan. Sastry's research at the university focuses on t

Got cells? Battery supplier CEO warns of limited battery supply for electric vehicles

Over the last decade, billions of consumer electronics devices have been built and powered by lithium ion batteries and cars appear to be the next big li-ion applications. Even with all the lithium ion battery production that exists today however, capacity remains nowhere near where it needs to be to power all the plug-ins that are coming. Just think of the Tesla Roadster, which relies on standard 18650 cells like those used in laptop computers. A laptop typically uses six to nine of these cells

Report: Ford going with LG Chem for lithium ion cells?

A report out of South Korea today is claiming that Ford has signed an exclusive deal with LG Chem to supply lithium ion cells for its future plug-in vehicles. Until now, Ford has worked primarily with Johnson Controls-Saft for its cell supply and the Escape plug-in hybrid test fleet uses batteries from that supplier. In 2009, Ford announced that JCS would be the supplier of batteries for the Transit Connect BEV and the upcoming 2012 plug-in hybri
