Abstract

A gel polymer electrolyte (GPE) supported by a polyimide (PI) nanofiber membrane with Li_6.5La₃Zr_1.5Ta_0.5O₁₂ (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.
