摘要：
Nanostructured graphene supported LiMn1/3Ni1/3Co1/3O2 has been prepared by the co-precipitation method and used as the cathode material for lithium-ion batteries. The structure and morphology of the composite were examined using atomic force microscopy, scanning electron microscopy, high-resolution transmission electron microscopy, and x-ray diffraction. The composite cathodes made of graphene nanosheet supported LiMn1/3Ni1/3Co1/3O2 showed superior electrochemical performance and increased capacity compared to raw LiMn1/3Ni1/3Co1/3O2 electrodes. The outstanding electrochemical behavior of graphene supported LiMn1/3Ni1/3Co1/3O2 was ascribed to the increased electrical conductivity and high structural stability resulting from the addition of graphene.
