高性能固态锌−空气电池的丙烯酰胺与醚类聚合物凝胶电解质

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.
