Multi-component hollow nanostructure endows tin dioxide with outstanding lithium storage performance

Abstract

Herein, the huge volume variation and poor conductivity issues of SnO2 incurred are well addressed by fabrication of a TiO2@SnO2@C hollow nanosphere composite (TiO2@SnO2@C HS) with a satisfying synergistic effect of component and structure. As a result, the as-fabricated TiO2@SnO2@C HS presents excellent lithium storage performance, delivering high capacities of 937.5 and 605.7 mAh g−1 at 200 and 1000 mA g−1 after 250 and even 1000 cycles, respectively. The facile fabrication process and excellent lithium storage performance may make this TiO2@SnO2@C HS a promising candidate for advanced lithium-ion battery anode materials.
