Abstract: A gel polymer electrolyte (GPE) supported by a polyimide (PI) nanofiber membrane with Li6.5La3Zr1.5Ta0.5O12 (LLZTO) nanoparticles (PI/LLZTO/GPE) shows excellent flexibility and electrochemical properties, the ionic conductivity is 1.87 mS cm−1 and the Li+ transfer number is 0.64 at room temperature. The assembled Li metal battery with a LiFePO4 (LFP) cathode retains a 56.4 mA h g−1 discharge capacity at 10C. [ABSTRACT FROM AUTHOR]
