Electrolyte cosolvent: We employed methyl (2,2,2-trifluoroethyl) carbonate (FEMC) as a co-solvent for the [LiTFSI]3[Pyr14FSI]4 (ILE) to enhance the cycling stability cathode materials. Experimental results indicate that the introduction of FEMC can effectively form a LiF-rich cathode electrolyte interface (CEI) layer, which effectively suppress the cracking of secondary particles and contribute to enhance the performance of the high-mass loading of Li||LiFePO4 (LFP) cells.

氟化碳酸盐辅助离子液体电解质可实现高容量锂金属电池
电解质共溶剂：我们采用(2,2,2-三氟乙基)碳酸甲酯(FEMC)作为[LiTFSI] 3 [Pyr 14 FSI] 4 (ILE)的共溶剂，以增强正极材料的循环稳定性。实验结果表明，FEMC的引入可以有效形成富含LiF的阴极电解质界面（CEI）层，有效抑制二次粒子的破裂，有助于提高Li||LiFePO 4的高质量负载性能（ LFP）细胞。
