Hitachi Maxell claims new Li-ion battery with 20x the power

Nikkei's reporting that Hitachi Maxell, in association with Nagasaki University, NIAIST, and Fuji Heavy Industries, has developed a new kind of lithium ion battery that can supposedly store 20 times the power, but is also cheap and easily mass produced. Apparently this new kind of battery drops cobalt, an expensive staple of the traditional Li-ion recipe, instead making use of nano-infused lithium with manganese. You know how it goes though -- unrealistic and exponential battery developments are all well and good, but until we see it productized, we're not exactly liable to buy into the hype.
