'Nanochains' Could Increase Battery Capacity

Purdue University

WEST LAFAYETTE, Ind. -- How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery's negative electrode material. If the battery runs out of these ions, it can't generate an electrical current to run a device and ultimately fails. Materials with
