An excellent rechargeable PP14TFSI ionic liquid dual-ion battery

An ionic liquid dual-ion battery with pure 1-butyl-1-methylpiperidinium bis(trifluoromethylsulfonyl)imide as the electrolyte was developed, which exhibited a high discharge plateau initiated at 4.4 V, a well-defined capacity of 82 mA h g −1 , an ultrawide charge/discharge potential range of 1.0-5.0...

Zusammenfassung:An ionic liquid dual-ion battery with pure 1-butyl-1-methylpiperidinium bis(trifluoromethylsulfonyl)imide as the electrolyte was developed, which exhibited a high discharge plateau initiated at 4.4 V, a well-defined capacity of 82 mA h g −1 , an ultrawide charge/discharge potential range of 1.0-5.0 V and a superior stability of ∼100% capacity retention for 600 cycles. PP 14 TFSI dual-ion cells exhibit superior performance of a 4.4 V discharge plateau and 600 cycles without capacity decay.
