| 摘要 |
The present invention relates to a method for preparing a graphene/HE-NCM composite, wherein more than one HE-NCM particles of the formula (1) xLi2MnO3•(1-x)LiNiyCozMn1-y-zO2, wherein 0<x<1, 0<y<1, and 0<z<1, are in electrical contact with each other via one or multiple graphene flakes, said method including: a) dispersing HE-NCM particles in a solution of graphene oxide by ultrasonication to give a dispersion; b) lyophilization of the dispersion to give a graphene oxide/HE-NCM composite; c) thermal decomposition of the graphene oxide/HE-NCM composite to give the graphene/HE-NCM composite. The present invention further relates to a graphene/HE-NCM composite for lithium ion battery prepared by said method, an electrode material and a lithium ion battery comprising said graphene/HE-NCM composite. |
