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(+)).
本文描述了一种二氧化锡（SnO2）空心纳米立方体制备方法及其锂离子充放电性能。SnO2 是锂离子电池应用中最著名的阳极材料之一，因为它具有高的嵌锂-脱锂容量。高表面积的空心纳米结构是优选的，因为它们可以容纳大的体积变化，并在充放电循环中保持电极材料的结构稳定性。在这项研究中制备的 SnO2 空心立方体能在 0.02 至 2.0 V（相对于 Li/Li(+)）的 0.2 C 电流密度下，初始循环的放电容量高达 1783 mA h g(-1)，在 30 次循环后仍有 546 mA h g(-1)。
