Engineering of multi-shelled SnO2 hollow microspheres for highly stable lithium-ion batteries

Abstract

Uniform multi-shelled SnO₂ hollow microspheres were synthesized through a sequential hard template method, and their electrochemical properties were investigated for their use as anodes for lithium-ion batteries. The multi-shelled SnO₂ hollow electrode materials not only maintain a hierarchical structure during lithium ion insertion/extraction processes, but also improve the capacity of lithium-ion batteries.
