The alkaline Al-air battery is a kind of chemical battery exhibiting high theoretical energy density. However, the hydrogen evolution corrosion is the primary barrier to its widespread application. This work reports the inhibition effects of Triton X-100 (TX-100) and calcium citrate (Ca-citrate), as corrosion inhibitors for the Al-air battery anode in 4 M sodium hydroxide solution. It shows that the composite corrosion inhibitors have good synergistic effect with the corrosion inhibition efficiency of 81.39 %. It is found that the interfacial film is formed via the route of ‘Interface Enhancements’. Moreover, the addition of TX-100 and Ca-citrate significantly improves the discharge performance of the Al-air battery. This electrolyte regulation strategy offers a way to enhance the Al-air battery's performance in alkaline medium.

多功能复合添加剂对碱性铝空气电池阳极析氢反应的影响


碱性铝空气电池是一种具有高理论能量密度的化学电池。然而，析氢腐蚀是其广泛应用的主要障碍。这项工作报告了 Triton X-100 (TX-100) 和柠檬酸钙 (Ca-citrate) 作为铝空气电池阳极腐蚀抑制剂在 4 M 氢氧化钠溶液中的抑制效果。结果表明，复合缓蚀剂具有良好的协同作用，缓蚀效率达到81.39%。研究发现，界面膜是通过“界面增强”途径形成的。此外，TX-100和柠檬酸钙的添加显着提高了铝空气电池的放电性能。这种电解质调节策略提供了一种增强铝空气电池在碱性介质中性能的方法。
