Abstract:
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: Li1+aMxMn2−xO4−zAz (1) where −0.1≤a≤0.1, 0.3≤x≤0.8 and 0≤z≤0.1.
