ABSTRACT:
The present invention provides a positive-electrode active material powder, which comprises a granular material (A) capable of doping/dedoping lithium ions and a deposit (B) placed on the surface of the material in a granular or layered form (herein, the material (A) and the deposit (B) are not the same), the percentage of [volumetric sum of particles having a particle diameter of 1 μm or less]/[volumetric sum of entire particles] being 5% or less.
