Electronics Makers Lead the Charge in Quest for Longer Battery Life
But trouble is looming for the battery world. While lithium-ion batteries represent today’s cutting edge, the gadgetry that depends on them is advancing more quickly than the power technology. As mobile devices take on richer features, battery life has become a key issue for gadget developers, and now manufacturers need to go one better than lithium-ion, in both size and energy output.

Last year, NTT DoCoMo exported the successful i-mode concept overseas. A crucial part of that concept is the much talked-about mobile content and service provider “ecosystem” and – sure enough – Japan’s ecosystem players are following Big D’s path. Today we focus on three smaller players that have found honest-to-goodness cash revenue in Europe due at least in part to their Japan antecedents. Ironically, none are working with any of the baby i-modes over there, showing you don’t need DoCoMo to do what DoCoMo does – anywhere.
