摘要
由单质硫与聚丙烯腈合成一种新型含硫复合正极材料。通过XRD、SEM、FTIR对含硫聚丙烯腈复合正极材料进行了表征,利用循环伏安法和电池充放电测试了材料的电化学性能。结果表明:此正极材料表现了比较好的电化学性能,其初始放到容量达到690 mAh/g,40次循环放电容量仍为488 mAh/g。
A new type of sulfur-containing composite cathode material was synthesized by heating elemental sulfur and polyacrylonitrile. The sulfur-containing polyacrylonitrile composite anode materials were been characterized by XRD, SEM, FTIR. The electrochemical properties were investigated by cyclic voltammetry and charge-discharge tests. It was revealed that the cathode material exhibited a good electrochemical performance with the initial discharge specific capacity up to 690 mAh/g and a stable capacity approximate 488 mAh/g after 40 cycle numbers.
