由于其高理论容量、增强的安全性和低成本，水性铝离子电池已成为锂离子电池的有前景的替代品。然而，它们的实际应用仍然受到不均匀铝沉积、析氢反应和循环过程中腐蚀的阻碍，特别是在极端温度和高负载条件下。在这项研究中，设计了一种由Al（ClO4）3·9H2O和氨基甲酸甲酯以1:4摩尔比组成的水合共晶电解质，以提高水性铝离子电池在宽温度范围内的稳定性。优化的电解质形成缺水、弱溶剂化的结构[Al3+（MC）2（H2O）2（ClO4-）2]+，这在动力学上促进了均匀的铝沉积/剥离行为。此外，这种电解质有助于在铝阳极表面形成致密、富含阴离子的固体电解质界面层，保持阳极的长期稳定性。Al//Al对称电池在0.2 mA cm–2的电流密度下稳定循环600小时，而Al//聚苯胺（PANI）全电池在1 a g–1下循环1100次后，比容量保持在117.7 mAh g–1（基于PANI的质量）。值得注意的是，这种电解质在-15至50°C的宽温度范围内也表现出优异的循环稳定性，为大型储能系统中的铝离子电池应用提供了宝贵的设计原则。
