摘要

Nickel oxide (NiO) nanoparticles were directly formed on graphene nanosheets through in situ thermal decomposition of Ni(NO3)(2)center dot 6H(2)O and were anchored tightly on the graphene surface. During the charge-discharge process, graphene nanosheets served as a three-dimensional conductive network for the NiO nanoparticles. The lithiation-induced strain was naturally accommodated because of the constraint effect of graphene. Thus, pulverization of NiO nanoparticles was effectively prevented.
