Room-temperature Facile Synthesis of Co3O4 Nanoflakes as Anode Material for Li-ion Rechargeable Batteries

There have been numerous reports on the synthesis of Co3O4 nanoparticles with a wide variety of nanostructures using different chemical methods. Many such approaches involved the synthesis of the metal hydroxide followed by thermal annealing to obtain the oxide. Recently, several low-temperature chemical methods have been developed. However, these procedures typically involve tedious experimental parameters. In this study, we developed a simple, strategic room-temperature approach to obtain hierarchical arrays of Co3O4 nanoflakes. The properties of the obtained material (phase, morphology, and structure) were analyzed comprehensively by techniques. The Co3O4 nanoflakes show superior electrode performance as an anode material in Li-ion rechargeable batteries, in terms of cycle life and rate capability, that is suitable for next-generation energy storage applications.
