摘要

PPROBLEM TO BE SOLVED: To industrially advantageously provide a nickel-manganese-cobalt based complex oxide and a laminar lithium-nickel-manganese-cobalt based complex oxide capable of obtaining a lithium secondary cell having high capacity, excellent rate characteristics, high temperature cycle characteristics and a good performance balance. PSOLUTION: The laminar lithium-nickel-manganese-cobalt based complex oxide is obtained by using a nickel-manganese-cobalt based complex oxide being a single phase of a complex oxide having a spinel structure represented by a specific formula as a precursor. The secondary particles are formed by aggregation of primary particles, a standard deviation (s) of an average primary particle diameter is 0.15 or less, and each element of nickel, manganese and cobalt is uniformly dispersed. The lithium secondary cell comprises the laminar lithium-nickel-manganese-cobalt based complex oxide. PCOPYRIGHT: (C)2011,JPO&INPIT
