Researchers at the Massachusetts Institute of Technology have been looking at where the bottlenecks are inside lithium ion batteries that limit charging and discharging rates learned some interesting things. Lithium iron phosphate chemistry is particularly promising in terms of high charge and discharge rates. They found that some new processes for manufacturing the lithium phosphate coating on lithium iron phosphate crystals could provide for better access to the lithium ions allowing them to m

A123 Systems is getting a lot of media attention lately for their lithium ion battery developments right now and the New York Times has jumped on the bandwagon. A123 who is partnering with Cobasys was one of two companies that recently got development contracts from General Motors to supply batteries for the plug-in hybrid Saturn Vue program, the other being the Johnson Controls/Saft joint-venture.
