Japan came with another possibly innovative invention. Drs Hiroyuki Nishide, Hiroaki Konishi and Takeo Suga at Waseda University developed a polymer based battery.
The plastic strip is about as thick as a piece of film can charge in one minute and hold energy very well.
Theres some things to work out with it, but if its released and available for commercial use, electronics will definitely get thinner. I'd expect Motorola and Apple to really be on it.
