摘要
利用静电纺丝技术与碳热还原相结合,制备了具有较高容量和较好循环性能的Sn/C无纺布纤维膜。利用扫描电镜(SEM),X射线衍射(XRD),表征Sn/C纤维的形貌和结构。样品首次循环得到较高的充放电容量,分别为1 329.8和808.6 mA·h/g。循环40圈以后,充电容量仍保持在743 mA·h/g,为第二圈充电容量的97.5%。
A large Sn/C non-woven film with high capacity and good cycleability have been prepared by an electrospinning of a mixture solution of SnCl4 and PAN,followed by heat-treatment at high temperature.Scanning electron microscopy（SEM）,and X-ray diffraction（XRD）analyses demonstrated the morphology and the structure of the Sn/C nanofibers.At first cycle,the Sn/C nanofiber delivers high charge and discharge capacities,808.6and1 329.8mA·h/g,respectively.After 40 cycles,the discharge capacity remains 743mA·h/g,which is 97.5% of the capacity of the second cycle.
