以碳凝胶作导电骨架,合成硫/碳凝胶复合物.XRD、SEM等表征显示,该复合材料完全保持了碳凝胶的形貌,颗粒大小在10μm以下,硫吸附在碳凝胶内部空隙中呈无定形态,表现出良好的电化学性能.以0.1C放电,该材料首圈放电容量达到1311mAh/g.0.2C循环充放,首圈放电容量为1107.1mAh/g,30周充放电后,放电容量仍不低于800mAh/g. Carbon nanofibers were used as conductive framework to synthesize sulfur / carbon gel composites. XRD, SEM and other characterizations showed that the composites completely preserved the morphology of carbon gels. The interstitial amorphous state, showing good electrochemical performance.With 0.1C discharge, the material discharge capacity of the first lap reached 1311mAh / g.0.2C cycle charge and discharge, the first lap discharge capacity of 1107.1mAh / g, 30 weeks charge After discharge, the discharge capacity is still not less than 800mAh / g.
