Abstract

SnO₂@Co₃O₄ hollow nano-spheres have been prepared using the template-based sol-gel coating technique and their electrochemical performance as an anode for lithium-ion battery (LIB) was investigated. 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 Li₂O reduction reaction during cycling.[Figure not available: see fulltext.]
