The size of synthesized hollow spheres was about 50 nm with the shell thickness of 7-8 nm. The fabricated SnO2@Co3O4 hollow nano-sphere electrode exhibited an extraordinary reversible capacity (962 mAh-g-1 after 100 cycles at 100 mA-g-1), good cyclability, and high rate capability, which was attributed to the Co-enhanced reversibility of the Li20 reduction reaction during cycling.展开更多
