摘要: This chapter deals with the investigation of lithium storage in rGO/Fe3O4 nanocomposites prepared by a simple precipitation method followed annealing at different temperatures and environments such as 80 °C air, 600 Ar, 700 Ar Ar–H2. The sample obtained exhibit high surface area 30 m2 g−1. Electrochemcial properties rGO wrapped magnetite nanoparticles were investigated cyclic voltammetry galvanostatic cycling EIS studies. They stable capacity minimal fading. In addition, they good rate capability. composite Ar–H2 exhibits best capability reversible 480 mAh g−1 current density 3000 mA
