Self-standing Li_1.2Mn_0.6Ni_0.2O₂/graphene membrane as a binder-free cathode for Li-ion batteries.

ABSTRACT: Lithium-rich transition-metal layered oxides (LROs), such as Li_1.2Mn_0.6Ni_0.2O₂, are promising cathode materials for application in Li-ion batteries, but the low initial coulombic efficiency, severe voltage fade and poor rate performance of the LROs restrict their commercial application. Herein, a self-standing Li_1.2Mn_0.6Ni_0.2O₂/graphene membrane was synthesized as a binder-free cathode for Li-ion batteries. Integrating the graphene membrane with Li_1.2Mn_0.6Ni_0.2O₂ forming a Li_1.2Mn_0.6Ni_0.2O₂/graphene structure significantly increases the surface areas and pore volumes of the cathode, as well as the reversibility of ox
