Enhanced Electrochemical performance at high temperature of Cobalt Oxide/Reduced Graphene Oxide Nanocomposites and its application in lithium-ion batteries.

ABSTRACT: We report a microwave irradiation method for the preparation of reduced graphene oxide (RGO) based Co₃O₄ nanocomposites as anodes for lithium-ion (li-ion) batteries. The Co₃O₄/RGO nanocomposites displayed good electrochemical behavior as anodic materials for li-ion batteries when compared to pure Co₃O₄. The Co₃O₄/RGO nanocomposites with low RGO content resulted in stable electrochemical performance with 100% coulombic efficiency at a high current density of 500 mA/g for 50 cycles. The enhanced capacity of the Co₃O₄/RGO nanocomposites is due to the incorporation of RGO, which resulted in a four times larger surface area than that of Co₃O₄. This increased surfac
