TiO₂ Hollow Spheres With Flower-Like SnO₂ Shell as Anodes for Lithium-Ion Batteries.

ABSTRACT: SnO₂ is a promising anode material for lithium-ion batteries due to its high theoretical specific capacity and low operation voltage. However, its poor cycling performance hinders its commercial application. In order to improve the cycling stability of SnO₂ electrodes, novel flower-like SnO₂/TiO₂ hollow spheres were prepared by facile hydrothermal method using carbon spheres as templates. Their flower-like shell and mesoporous structure highlighted a large specific surface area and excellent ion migration performance. Their TiO₂ hollow sphere matrix and 2D SnO₂ nano-flakes ensured good cycle stability. The electrochemical measurements indicated that novel flower-like SnO₂/TiO₂ hollow spheres delivered a
