Less bang for your buck
Abstract:
Matsushita is not the only firm racing to make a better lithium-ion cell. Toshiba has a lithium-ion battery that relies on nanotech materials, made of particles smaller than a billionth of a metre, that can be recharged to 80% of capacity in one minute. America's 3M is introducing electrolytes for lithium-ion cells that don't burst into flames when overheated.
