Abstract Metal oxides with a higher capacity than graphene-based materials have actively studied as an anode material. However, they had inherent limitations such as a large volume change and low electrical conductivity. To overcome such drawbacks, the NiO/GO hybrid was synthesized through two step process: hydrothermal synthesis and subsequent heat treatment. The physicochemical properties are characterized by XRD, SEM, TEM, FT-IR, RAMAN and BET analysis. The TEM image showed that nanosized NiO particle with a hexagonal morphology was attached on the graphene nanosheets, indicating the interaction between the NiO and the graphene sheet. According to galvanostatic discharge/charge, the NiO/graphene hybrid had superior capacity and high rate capability in sodium storage due to the complementary synergy effect between the NiO nanoparticle and the graphene nanosheet. It is expected that this hybrid could be widely utilized as active material for advanced energy system storage.
