摘　　要：Organic ionic plastic crystals (OIPCs) composed of 1-ethyl-1-methyl pyrrolidinium bis(fluorosulfonyl) imide (P12FSI) and lithium bis(fluorosulfonyl)imide (LiFSI) was used as electrolyte for lithium-oxygen batteries. Since P12FSI-LiFSI electrolyte exhibited high ionic conductivity, good chemical stability and wide electrochemical window, the battery showed good rate capability, excellent cycling stability and can be operated stably for 320 cycles under a fixed capacity of 500 mAh/gcarbon. The use of OIPCs electrolyte could provide a new avenue for the development of high-performance Li-O2 batteries.Organic ionic plastic crystals（OIPCs）composed of 1-ethyl-1-methyl pyrrolidinium bis（fluorosulfonyl）imide(P12FSI)and lithium bis（fluorosulfonyl）imide（LiFSI）was used as electrolyte for lithium-oxygen batteries.Since P12FSI-LiFSI electrolyte exhibited high ionic conductivity,good chemical stability and wide electrochemical window,the battery showed good rate capability,excellent cycling stability and can be operated stably for 320 cycles under a fixed capacity of 500 mAh/gcarbon.The use of OIPCs electrolyte could provide a new avenue for the development of high-performance Li-O2 batteries.
