Nanostructured MnO2/CeO2 composite as anode material for high performance Li-ion battery

MnO2/CeO2 nano-composite with the mixed nanostructures (nano-rod and nao-particles) have been synthesized by simple hydrothermal method. As lithium-ion battery anode, the obtained specific capacities of the nanocomposite are 850, 750, 630 and 555 mAh g-1 at 100, 200, 500 and 1000 mA g-1. These admirable lithium storage properties originate from reinforcing the ability of buffering the volume change, large effective surface area and improved electronic conductivity.
