The MnO2/CeO2 nano-composite with mixed nanostructures (nano-rod and nanoparticles) synthesized by a hydrothermal method shows excellent lithium storage performance as an anode in lithium-ion batteries, with specific capacities of 850, 750, 630, and 555 mAh g-1 at different current rates. This is attributed to its ability to enhance volume change buffering, provide a large effective surface area, and improve electronic conductivity.
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.
