正極活物質
Document Type and Number:
Japanese Patent JP6843922
Kind Code:
B2
Abstract:
The amount of lithium ions that can be received and released in and from a positive electrode active material is increased, and high capacity and high energy density of a secondary battery are achieved. Provided is a lithium-manganese composite oxide represented by LixMnyMzOw, where M is a metal element other than Li and Mn, or Si or P, and y, z, and w satisfy 0≰x/(y+z)<2, y>0, z>0, 0.26≰(y+z)/w<0.5, and 0.2
