摘要：

为了改善传统纽扣式锌-空气电池电解质泄露以及金属外壳易腐蚀的弊端,同时优化锌-空气电池的性能,对电解质中引入添加剂进行了研究。将丙烯酰胺与醚类聚合物混合制备的凝胶电解质与由纯丙烯酰胺制备的电解质进行对比,分别将两种凝胶电解质组装成纽扣式锌-空气电池进行充放电性能测试,并对两组测试结果进行比较分析。结果表明:与传统的聚丙烯酰胺电解质相比,加入了醚类聚合物的新型电解质在粘性、导电性等方面得到明显改善,组装的纽扣式锌-空气电池可以在5 mA的电流下循环充放电35 h以上,具有更好的循环稳定性;在丙烯酰胺中加入醚类聚合物对电解质的性能以及锌-空气电池的性能起到了改善作用。

Abstract:

Introducing additives into the electrolyte was investigated to improve the disadvantages of electrolyte leakage and corrosion of metal shell of traditional button zinc-air battery and to optimize the performance of zinc-air battery meanwhile. The gel electrolyte prepared by mixing acrylamide and ether polymers was compared with the electrolyte prepared by pure acrylamide. The charge and discharge performance of button zinc-air batteries composed of two kinds of gel electrolytes were tested respectively, and the results of the two groups of tests were compared and analyzed. The results show that compared with the traditional polyacrylamide (PAM) electrolyte, the viscosity and ionic conductivity of the new electrolyte with ether polymer are significantly improved. The assembled button zinc-air battery shows so better cycle stability that it can be charged and discharged at 5 mA current for more than 35 h, which indicates that the addition of ether polymer to acrylamide can improve the performance of electrolyte and zinc-air battery.

Key words: button-type zinc-air battery, gel electrolyte, charge-discharge performance, cycle stability
