摘要: 应用复合电镀法制备Sn-SBA15电极.充放电测试得其初始放电(嵌锂)容量,达到1075mAh/g.充电(脱锂)容量为630mAh/g,经过50周循环后充放电容量均保持在400 mAh/g以上.XRD分析表明,Sn-SBA15电极具有四方晶型锡结构;而SEM观察到电极表面的蜂窝状结构.交流阻抗谱结果显示,Sn-SBA15电极表面有SEI膜的生成.

Abstract: Sn-SBA15 anode was prepared by composite electroplating.The first discharge and charge capacity was 1075mAh/g and 630mAh/g respectively.After fifty charge/discharge cycles,the charge and discharge capacity of Sn-SBA15 were retained above 400mAh/g.XRD patterns indicated that the Sn-SBA15 has tetragonal crystal type.SEM images showed that the Sn-SBA15 had a honeycombed surface.EIS results indicated that there was SEI film formed on the surface of Sn-SBA15 electrode.

Key words: composite electroplating, Sn, lithium-ion batteries, CV, EIS, XRD, SEM
