Just not really much new stuff in battery tech lately. Some neat research being done, though. For example I read something a while back about Stanford (I think) researchers adding carbon nanotubes or something like that to the anode (or cathode?) of Li-ion batteries. Supposedly it would be able to increase capacity by up to 10 times. Just think about that, a laptop that gets 60 hour battery life instead of 6. Crazy.
And then there are completely new technologies that could supplant chemical batteries one day. Supercapacitors, fuel cells, etc.
