Progress of Research on Li-Rich Cathode Materials xLi2MnO3·(1-x) LiMO2(M=Ni, Co, Mn...) for Li-Ion Battery

With the development of the portable electronics industry, the need for more efficient power sources has been enlarged. Lithium-ion batteries are able to deliver high energy densities, high capacity and long cycle life at reasonable costs among competing energy storage technologies. The major goal of this paper is to introduce the promising Li-rich cathode material xLi2MnO3·(1-x) LiMO2(M=Ni, Co, Mn...), which owns enhanced energy and power density, high energy efficiency, superior rate capability and excellent cycling stability due to different modification methods.
