摘要: Abstract The electrical properties of solvent-free, PEO–LiTFSI solid polymer electrolytes (SPEs), incorporating different N -alkyl- -methylpyrrolidinium bis(trifluoromethanesulfonyl)imide, PYR 1A TFSI, ionic liquids (ILs), are reported. For this purpose, TFSI materials containing side alkyl groups with chain-length and branching, i.e., n -propyl, sec -butyl, iso -butyl -pentyl, were properly synthesized homogeneously incorporated into the SPE samples without phase separation. addition ILs to results in a large increase conductivity decrease interfacial resistance lithium metal anode. Most PEO–LiTFSI–PYR showed similar conductivities (>10 −4 S cm −1 at 20 °C) stable values (400 Ω cm 2 40 °C 3000 Ω cm upon several months storage. Preliminary battery tests have shown that Li/P(EO) 10 LiTFSI + 0.96 PYR TFSI/LiFePO 4 solid-state cells capable deliver capacity 125 mAh g 100 mAh g 30 °C 25 °C, respectively.
