A locally concentrated ionic liquid electrolyte formed via diluting ionic liquid electrolytes with non-solvating 1,2-difluorobenzene (dFBn) co-solvent is proposed for wide-temperature-range Al−S batteries. It presents better fluidity and ionic conductivity without affecting the AlCl₄⁻/Al₂Cl₇⁻ equilibrium, as well as a faster kinetics, enabling a long-life-span Al−S batteries under −20–40 °C.

用于宽温范围铝硫电池的局部浓集离子液体电解质

提出了一种用于宽温度范围 Al−S 电池的局部浓缩离子液体电解质，该电解质是通过用非溶剂化 1,2-二氟苯 (dFBn) 共溶剂稀释离子液体电解质而形成的。它具有更好的流动性和离子电导率，而不影响AlCl ₄ ^- /Al ₂ Cl ₇ ^-平衡，以及更快的动力学，使得Al−S电池在-20–40 °C下具有长寿命。
