用循环伏安法和恒电流扫描法及X射线衍射法研究了不同成份和浓度的中性电解液中的锌电极的电化学行为 ,并通过向中性电解液中添加季铵盐缓蚀剂 ,考察缓蚀剂在锌电极反应中的缓蚀作用 ,探讨锌电极的反应机理。试验结果发现在NH4Cl(浓度为 4mol/L) +KCl(浓度为 1mol/L)混合溶液中添加季铵盐缓蚀剂后既可抑制锌电极的阳极溶解 ,又可提高其析氢过电位和析氢电流密度 ,是有效改善锌 空电池性能的途径之一。
Cyclic voltammetry and galvanostatic scanning and X-ray diffraction were used to study the electrochemical behavior of zinc electrodes in neutral electrolytes of different compositions and concentrations. The quaternary ammonium salt corrosion inhibitor The corrosion inhibition effect of corrosion inhibitor on zinc electrode was investigated, and the reaction mechanism of zinc electrode was discussed. The results showed that the addition of quaternary ammonium salt inhibitor to NH4Cl (4mol / L) and KCl (1mol / L) mixed solution not only inhibited the anodic dissolution of zinc electrode but also enhanced the overpotential of hydrogen evolution and hydrogen evolution Current density is one of the ways to effectively improve the performance of zinc-air batteries.
