Positive electrode material for lithium secondary battery, method for producing the same, and lithium secondary battery |
摘要 |
A positive electrode material for a lithium secondary battery which is high in safety, high in capacity, excellent in rate performance and high temperature storage performance and high in charge/discharge efficiency is provided. The positive electrode material for a lithium secondary battery is obtained by adding Al to a Li-Ni-Co-Ba-O system raw material or preferably by adding Al and an amorphous phase of an oxide thereto. The positive electrode material for a lithium secondary battery is a composite oxide having a total composition represented by LiaNibCocBadAleOx or LiaNibCocBadAleMfOx where M: one or more elements selected from the group consisting of Li, Na, K, Si, Ba, B, P and Al a: 1.0 to 1.2 mol b: 0.5 to 0.95 mol c: 0.05 to 0.5 mol d: 0.0005 to 0.01 mol e: 0.01 to 0.1 mol f: 0.01 mol or less (not inclusive of 0) |
