摘　　要：选取钛片作为集流体,在析氢抑制剂中掺杂不同含量的SnO_2,制作炭电极。为测定其电化学性能,采用线性扫描、循环伏安、交流阻抗、恒流充放电进行测试。实验发现:炭电极中掺杂SnO_2可显著抑制析氢,并且能够明显地提高比电容,而掺杂4.9%的SnO_2时性能最佳。Titanium plate was chosen as current collector, carbon electrode was made by doping different contents of SnO_2 to hydrogen evolution inhibitor. The electrochemical performance was tested by linear sweep voltammetry,cyclic voltammetry, electrochemical impedance spectroscopy and galvanostatic charge-discharge. The experiment results show that carbon electrodes doped with SnO_2 can significantly inhibit the hydrogen evolution and improve the specific capacitance. And the best adding proportion of SnO_2 is 4.9 %.
