摘要:
A lithium nickel composite oxide, having small inner resistance, large battery capacity and high thermal stability, can be used as a positive electrode active material for a non-aqueous electrolyte secondary battery.

This is obtained by filtering and drying the fired powder after water washing, wherein it is dried at 90° C. or lower, till moisture is reduced to 1% or less by mass in drying, and then at 120° C., and under gas atmosphere where content of compound components containing carbon is 0.01% or less by volume, or under vacuum atmosphere.
