摘要
采用扫描电子显微镜(SEM)、循环伏安法、充放电实验,研究了不同修饰工艺获得的石墨/碳纳米管CNT电极的表面形貌和电化学特性,并尝试应用于锌溴电池。研究结果表明:采用碳纳米管修饰石墨电极能明显改善石墨电化学活性、并提高锌溴电池充电电流大小及电池容量。
The morphology and electrochemical performance of three kinds of graphite electrodes modified by carbon nano tube （CNT） were studied by SEM and cyclic voltammetry （CV）, and the charge/discharge properties are studies when the modified electrodes applied in zinc - bromide batteries. The results indicated that the graphite electrodes modified by CNT could improve their electrochemical activity, charge current and capacity of zinc - bromide battery.
