| 摘 要： | 采用聚丙烯腈与单质硫在一定条件下合成了一种新型含硫复合材料。用该材料作为活性物质制备的锂蓄电池正极具有高的质量比容量和良好的循环性能。还通过对该复合材料的结构表征初步推测,该复合材料含有硫醇基,由硫-硫键断裂和键合实现能量释放与存储。

| Abstract: | A novel S-containing polymer for the active composite material of cathode of the lithium ion battery was synthesized by heating polyacrylonitrile and elemental sulfur in certain conditions. The cathode made by S-containing composite material shows a high initial specific charge-discharge capacity with 800 mAh/g and good cycle ability. From the structural characteri-zation, it is deduced that this composite material includes a polymer with mercaptan attaching to the main carbon chain. |
