文摘

Concentrated Pyr12O1FTFSI0.6LiFTFSI0.4 electrolyte is liquid at ambient conditions. Better rate capability is achieved with concentrated ionic liquid electrolyte. Concentrated electrolyte is suitable for safer lithium metal batteries. Effective Li+ transport in concentrated electrolyte is higher than in the dilute electrolyte.
