Abstract

SnO₂ microspheres with controllable morphology were prepared via a hydrothermal-annealing method. The SnO₂ morphology can be tuned by using AlOOH sol and γ-Al₂O₃ as additive. The hollow SnO₂ microspheres with incomplete core-shell structure prepared with small amount of γ-Al₂O₃ presented the best cycling performance in Li-ion battery, exhibiting a specific capacity of 374.2 mAh g^-1 up to 100 cycles. The superior performance can be mainly attributed to the formation of more and smaller SnO₂ hollow microspheres and partial core-shell SnO₂ microspheres resulting from the γ-Al₂O₃ condensation nucleus. The unique hollow and core-shell composite structure of SnO₂ is capable of reducing the volume changes during Li insertion-extraction.
