摘要

以有机热解碳 (石墨 )为原料 ,用喷雾热蒸发法制备了用于锂离子电池负极的碳膜 .用循环伏安法和恒电流充放电法测试了所获碳膜的电化学性能 .测试结果表明 ,在第一循环周期中存在一个还原峰 ,该还原峰对应在电极表面形成固体电解质中间相膜 ;当充放电电流大小合适时 ,容量和X值都较大 .基于这些实验结果 ,可以认为所获得的碳膜能用作电池负极以相对测试其他正极材料电化学性能 .

Abstract

Carbon films were made using spray_thermal evaporation from a kind of pyrolytic carbon powder. The films obtained with graphite structure were both potentio_statically and galvanostaically tested. Cycling patterns indicated a reduction peak on the first cycle corresponding to the formation of solid electrolyte interface, and the capacity values and x values were quite acceptable compared to theoretical ones when charging_discharging current density was suitable. Based on the experimental results, the obtained carbon films could be used as anode materials for relatively determining the electrochemical performances of cathode materials.
