摘要
用塔菲尔曲线外推法、循环伏安法以及充放电法分别研究了锌多晶体电极、锌单晶体(002)晶面电极和(100)晶面电极在6 0mol/L的KOH溶液中的电化学行为。结果表明:在6 0mol/L的KOH溶液中,锌多晶体电极、锌单晶体(002)晶面电极和(100)晶面电极的腐蚀速度依次减小;锌单晶体电极可逆性更优;充放电循环过程中,在锌多晶体电极表面比锌单晶体电极表面更易生长枝晶。
The electrochemical performance of the electrodes of Zn polycrystal, Zn(002) and Zn(100) single crystals experiment in 6.0 mol/L KOH solution were studied by Tafel line extrapolation of potentiodynamic polarization curves, cyclic voltammetry and charge/discharge experiment.The results showed that in 6.0 mol/L KOH solution,the corrosion rate of Zn polycrystal, Zn(002) and Zn(100) single crystals decreased in turn; the reversibility of Zn single crystal was superior to Zn polycrystal. The dendrite growth of the surface of Zn polycrystal was easier than Zn single crystal during charge/discharge.
