摘要:
A positive electrode material for non-aqueous electrolyte secondary batteries having high rate characteristics and high energy density, and a battery using the same are provided. The non-aqueous electrolyte secondary battery includes a positive electrode containing a positive electrode material, a conductive agent and a binder; a negative electrode; a separator; and a non-aqueous electrolyte, in which the positive electrode material contains core particles and a coating material that covers from 10% to 90% of the surfaces of the core particles, the core particles are formed of a compound represented by LiaMbPO4 (wherein M represents at least one element selected from Fe, Mn, Co and Ni, and satisfies the relations: 0
