摘　　要：采用线性扫描法、交流阻抗、电位-阻抗曲线和恒流连放等方法,研究聚乙二醇系列(PEGn)对锌合金阳极电化学性能的影响。PEGn对锌合金电极的正常溶解过程有一定的阻化作用,但能抑制锌钝化过早的发生;不同相对分子质量的PEG对锌电极的影响不同。适量PEG600可抑制锌钝化的过早发生,提高碱性锌锰(碱锰)电池的放电容量和锌负极活性物质的利用率,电解液含0. 1%PEG600的LR6电池,室温1 200 m A恒流放电容量提高了13. 7%。The influence of polyethylene glycol series（ PEGn） on anodic behavior of zinc alloy was studied by linear sweep voltammetry,A. C. impedance,potential-impedance curve and galvanostatic continuous discharge techniques. The normal dissolution process of alloy electrode had been inhibited and premature occurrence of zinc passivation could be inhibited by PEGn. The PEGn with different molecular weights had different effects on zinc electrodes. The addition of appropriate amount of PEG600 could inhibit the premature occurrence of zinc passivation,which could improve capacity of alkaline ZnMnO2 battery and utilization of zinc anode. The LR6 battery,which was assembled by using zinc gelled containing 0. 1% of PEG600,exhibited 13. 7 % increasement of capacity at 1200 m A galvanostatic continuous discharge at room temperature.
