摘要：NiO nanowalls/graphene nanosheets (NiO/GNSs) nanocomposites are synthesized by a hydrothermal method, and their application as anodes of lithium-ion batteries has been investigated. NiO nanowalls were uniformly coated over the surface of graphene. NiO/GNSs nanocomposites exhibit extremely high cyclability and capacity. The reversible capacity is 844.9 mA h g(-1) at 0.1C rate (10 h per half cycle) and fades merely 7.1% after 50 cycles. The present results indicate that NiO/GNS nanocomposites have potential applications in lithium-ion battery anodes.
