摘要
利用水热法合成了纳米片状Sb_(2)WO_(6)(SWO-24,SWO-48),并对其作为锂离子电池负极进行了系统地研究.结果表明,SWO-48电极组装的电池具有较高的可逆容量和良好的循环性能,在电流密度为1.0 A/g时,可逆容量为572.9 mAh/g,循环后库伦效率高达98%.
Sb_(2)WO_(6)(SWO-24,SWO-48)with nanosheet morphology was synthesized by hydrothermal method and systematically studied as the anode of lithium ion battery.The results showed that the cell assembled with SWO-48electrodes had high reversible capacity and good cycle performance.At a current density of 1.0A/g,the reversible capacity is 572.9mAh/g,and the coulombic efficiency after cycling is as high as 98%.
