Abstract
This paper describes a new synthesis and lithium ion charge-discharge property of tin dioxide (SnO 2) hollow nanocubes. SnO 2 is one of the best-known anode materials for lithium-ion battery application because of its high lithiation-delithiation capacity. Hollow nanostructures 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 SnO 2 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 +).
