Singhal, Amit; Skandan, Ganesh

A low cost and scalable processes for producing nanostructured LiFexM1-xPO4 and nanostructured LiFexM1-xPO4/C composite powders, where 1≦x≦0.1 and M is a metal cation, such as Mn, Co, Ni, and V. Electronics made of either nanostructured LiFexM1-xPO4 powders or nanostructured LiFexM1-xPO4/C composite powders exhibit good electrochemical properties. The electronic conductivity of nanostructured LiFexM1-xPO4 powders is enhanced by intimately mixing them with ultrafine carbon particles. Thus, the use of nanostructured LiFexM1-xPO4/C composite powders will lead to high power density, low cost and environmentally friendly rechargeable Li-ion batteries.
