Abstract
Composite materials for a cathode of an electrochemical cell. The composite materials comprise Li[M1−xLix]O2 or yLi2MnO3.(1−y)LiMO2 (M=Ni, Co, Mn, 0<x<0.5, 0<y<1), and at least one of LiMn1.5Ti0.5O4 and LiMn1.5Ni0.5O4. A Li-ion electrochemical cell including a cathode comprising the composite materials is also provided. The Li-ion electrochemical cell controls irreversible capacity loss and maintain a good cycling stability.
