ANODE ACTIVE MATERIAL FOR HIGH VOLTAGE AND METHOD FOR MANUFACTURING SAME

摘要

Disclosed herein is a high voltage cathode active material and a method for preparing the same. The cathode active material includes particles of a spinel-type compound having a composition represented by Formula (1) and a carbon-based material present on surfaces of the particles of the spinel-type compound:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒLi 1+a M x Mn 2-x O 4-z A z €ƒ€ƒ€ƒ€ƒ€ƒ(1)
where -0.1‰¤a‰¤0.1, 0.3‰¤x‰¤0.8 and 0‰¤z‰¤0.1.
