Facile approach to synthesize CuO/reduced graphene oxide nanocomposite as anode materials for lithium-ion battery

Abstract An efficient synthesis is used for the first time to prepare CuO/reduced graphene oxide nanocomposite anode materials for lithium ion batteries. Initially, copper oxide (CuO) nanoparticles are synthesized via a simple, facile and inexpensive microwave-assisted method within short reaction times ( −1 and 1043.3 mAh g −1 with reversible capacity retention of 392.1 mAh g −1 and 516.4 mAh g −1 after 45 cycles respectively. The excellent electrochemical performance of CuO/reduced graphene oxide nanocomposite can be attributed to their unique structures, which intimately combine the conductive graphene nanosheets network with uniformly dispersed CuO nanoparticles.
