Abstract
This disclosure provides a positive electrode active lithium-excess metal oxide with composition LixMyO2 (0.6≦y≦0.85 and 0≦x+y≦2) for a lithium secondary battery with a high reversible capacity that is insensitive with respect to cation-disorder. The material exhibits a high capacity without the requirement of overcharge during the first cycles.
