| 摘 要： | 基于碱式氯化锌优异的半导体性能和石墨烯突出的导电性以及机械性能,利用机械化学法在室温下制备了石墨烯/碱式氯化锌复合材料,探索其电化学性能.循环伏安和恒流充放电测试研究表明:当扫描速率为5mV/s时,比电容最大为30.5F/g;当扫描速率为80mV/s时,电极材料出现极化现象,导致峰凸增加,比电容增大;当充放电电流密度为0.1A/g时,充放电时间最长,且循环性能较好.

| Abstract: | Graphene has excellent conductivity and mechanical property, and simonkolleite is a good semiconductor. To make use of the advantages of the both, a composite made of graphene and simonkolleite was synthesized by mechanochemical method at room temperature, and its electrochemical performance was analyzed. Cycle-voltammetry and constant current charge and discharge tests demonstrate that the maximum specific capacity is 30.5 F/g when the scan rate is 5 mV/s. The polarization may appear if the scan rate reaches 80 mV/s, resulting in the peak value of the specific capacitance. The time for charge and discharge is the longest with the current density of 0.1 A/g, and the cycle performance is also rather good. |
