摘要：
A positive electrode active material for producing a nonaqueous electrolyte secondary cell exhibiting an excellent high-rate charging/discharging performance and an excellent charging/discharging cycle performance and having a high energy density, and a nonaqueous electrolyte secondary cell exhibiting an excellent high-rate charging/discharging performance and an excellent charging/discharging cycle performance and having a high energy density. The main component of the positive electrode active material is a Li-Mn-Ni composite oxide, and the positive electrode active material is characterized in that the specific surface of the Li-Mn-Ni composite oxide measured by the BET method is 0.3 m2/g or above and 1.5 m2/g or below. The nonaqueous electrolyte secondary cell comprises such a positive electrode active material.
