Abstract

See full text

Provided is a method for preparing a graphene/ternary material composite for use in lithium ion batteries, comprising the following preparation steps: (a) mixing a ternary material and a graphene oxide powder in an organic solvent to form a mixed dispersion; (b) adding a reducing agent to the mixed dispersion from step (a), and carrying out a reduction reaction at a reduction temperature of 80-160° C. while stirring, to obtain a reduction reaction mixture after a reduction time of 60-240 min; and (c) evaporating the solvent from the reduction reaction mixture from step (b) while stirring, and drying and then annealing the mixture at a low temperature in an inert atmosphere to obtain a graphene/ternary material composite having a three-dimensional network structure. Also provided is a graphene/ternary material composite prepared by using this method.
