Sodium Chloride Template Synthesis of Cubic Tin Dioxide Hollow Particles for Lithium Ion Battery Applications

摘要

This paper describes a new synthesis and lithium ion charge—discharge property of tin dioxide (SnO2) hollow nanocubes. SnO2 is one of the best-known anode materials for lithium-ion battery application because of its high lithiation-delithiation capacity. Hollow nano-structures with high surface area are preferred, because they accommodate large volume changes and maintain the structural stability of electrode materials during charge-discharge cycles. The SnO2 hollow cubes made in this study had a discharge capacity of up to 1783 mA h g~(-1) for the initial cycle and 546 mA h g~(-1) after 30 cycles at a current density of 0.2 C between 0.02 and 2.0 V (vs Li/Li~+).
