Title:
導電性を改善した高容量の正極活物質（ａｃｔｉｖｅｍａｔｅｒｉａｌ）およびそれを含む非水電解質の２次電池
Document Type and Number:
Japanese Patent JP5866363
Kind Code:
B2
Abstract:
Disclosed is a cathode active material including a lithium manganese-based oxide. The lithium manganese-based oxide has a spinel structure, exhibits core-shell phase transition by which phase transition of a crystal structure occurs from a cubic structure to a tetragonal structure in a direction from the surface of particles to the center of the particles during discharging to the 3V region, and includes a conductive material at the shell to improve electrical conductivity of the tetragonal structure.
