Nickel oxide (NiO) as one of the anode electrode materials for lithium ion batteries (LIBs) has attracted considerable research attention. However, the poor electron conductivity and bad capacity retention performance greatly hinder its wide application. Herein, we prepared a novel three-dimensional (3D) hierarchical porous graphene@NiO@carbon composite via a simple solvothermal process, in which the graphene sheets were uniformly wrapped by porous NiO@carbon nanoflakes. In this case…
