Two cosolvents, MFSI and TFF, were synthesized and investigated for lithium metal batteries. Among the four different electrolytes, the TFF-containing electrolyte exhibited the highest coulombic efficiency of 99.59 %, which is due to the low redox potential of TFF promoting the anion reduction, leading to an inorganic SEI formation.

由具有低还原电位的氟化环醚实现的高性能锂金属电池
合成了两种共溶剂 MFSI 和 TFF,并研究了它们对锂金属电池的影响。在四种不同的电解质中,含 TFF 的电解质表现出最高的库仑效率,达到 99.59%,这是由于 TFF 的低氧化还原电位促进了阴离子还原,导致无机 SEI 的形成。
