A new Li−N interaction induced 1,2-dimethylimidazole (DMIm)-based deep eutectic gel polymer electrolyte is reported. The electron-donating DMIm dissociates LiTFSI well to form a deep eutectic electrolyte (DEE). The incorporation of polyvinylidene difluoride (PVDF) further changes the coordination environment of the Li⁺ ions. This kind of gel polymer electrolyte exhibits high ionic conductivity and electrochemical stability and enables the excellent long-term cycling performance for Li/LFP cells.

用于高性能锂金属电池的 Li-N 相互作用诱导的深共晶凝胶聚合物电解质

报道了一种新的 Li-N 相互作用诱导的 1,2-二甲基咪唑 (DMIm) 基深共晶凝胶聚合物电解质。给电子 DMIm 可以很好地解离 LiTFSI，形成深共晶电解质 (DEE)。聚偏二氟乙烯（PVDF）的加入进一步改变了Li ⁺离子的配位环境。这种凝胶聚合物电解质表现出高离子电导率和电化学稳定性，使Li/LFP电池具有优异的长期循环性能。
