Herein, we report a comparison of aluminum graphite dual‐ion cells (AGDICs) electrochemical characteristics employing the conventional 1‐ethyl‐3‐methylimidazolium chloride:aluminum trichloride (EMIMCl : AlCl₃) electrolyte and two popular deep eutectic solvents (DESs), namely urea : AlCl₃ and acetamide:AlCl₃. The three electrolytes′ characteristics have been evaluated in terms of Al‐stripping deposition capability and cycling behavior in AGDICs. The results evidence the EMIMCl : AlCl₃′s Al‐stripping deposition and rate capability in AGDICs superior characteristics addressed to the lower viscosity and higher conductivity with respect to the urea : AlCl₃ and acetamide:AlCl₃. On the other hand, the urea : AlCl₃ guarantees a much higher columbic efficiency in AGDICs, thanks to the superior electrochemical window stability.

铝石墨双离子电池用氯铝酸盐熔体的比较

在本文中，我们报告了使用传统的1-乙基-3-甲基咪唑鎓氯化物：三氯化铝（EMIMCl：AlCl ₃）电解质和两种流行的深共熔溶剂（DESs）对铝石墨双离子电池（AGDIC）电化学特性的比较。尿素：AlCl ₃和乙酰胺：AlCl ₃。三种电解质的特性已通过铝条沉积能力和AGDIC中的循环行为进行了评估。结果证明了AGDIC中EMIMCl：AlCl ₃的Al-stripping沉积和定速能力是针对尿素：AlCl ₃和乙酰胺：AlCl ₃的较低粘度和较高电导率的优异特性。另一方面，由于优越的电化学窗口稳定性，尿素：AlCl ₃保证了AGDIC中更高的哥伦比亚效率。
