Nanosize cobalt oxides (Co3O4) were synthesized by chemical decomposition of cobalt octacarbonyl (Co2(CO)8) in toluene at the low temperature of 130°C. The crystallinity and microstructure were characterized using X-ray diffraction and scanning electron microscopy. The electrochemical properties of electrodes made of nanosized Co3O4 particles were tested in Li-ion cells. The nanosized Co3O4 electrode material demonstrates a stable reversible lithium storage capacity of about 460 mAh/g over 30 cycles.
