Hitachi Maxell, along with Nagasaki University, NIAIST, and Fuji Heavy Industries (the parent company of Subaru, makers of the R1e electric car), announced that it has developed a new chemistry for lithium-ion batteries. Part of the change is dropping the expensive cobalt element and using "nano-infused lithium" with manganese (a very Japanese-sounding element! Pictured left.).
The claim: 20 times more power storage, and the ability to mass-produce it inexpensively. Lets hope it's true and that it will get out of the lab quickly. We'd even settle for only 10 times more power storage...
Via Hitachi Maxell claims new Li-ion battery with 20x the power
Update: Thanks to readers who have pointed out in the comments that the most likely explanation for this claim which seems too good to be true is that Engadget, our source since the original story is behind a pay barrier, either got a bad translation or made a mistake and the real story is 20x more power, and not 20x more energy storage. Other sources seem to claim that this is about storage, so we're not quite sure yet: IT Examiner, TechRadar, etc.
