A reduced graphene oxide (RGO)–magnetic oxide iron (Fe3O4) hybrid is prepared by homogenous coprecipitation and subsequent annealing. Characterization shows that Fe3O4 particles are nanoporous structures that anchor uniformly on the surface of RGO platelets. As an anode material for a Li ion battery, it has specific capacities for the first discharge and charge of 1528 and 1027mAhg−1 respectively,...
Reduced graphene oxide and nickel oxide composite was prepared by homogeneous coprecipitation and subsequent annealing. Characterizations show that NiO particles have a nanosheet-based microsphere structure and anchor uniformly on the surface of reduced graphene oxide platelets. As an anode for Li ion batteries, the composite has 1641mAhg −1 and 1097mAhg −1 specific capacities for...
