To satisfy the demand for high safety and energy density in storage devices, all-solid-state lithium metal batteries with solid polymer electrolytes (SPE) replacing traditional liquid separators have been proposed are increasingly regarded as one of most promising candidates next-generation systems. In this study, poly(vinylidene fluoride)-hexafluoropropylene/lignosulfonic acid (PVDF-HFP/LSA) composite electrolyte (CPE) membranes a micro area interface wetting structure were successfully prepared by incorporating LSA into PVDF-HFP matrix. The enhanced interaction between polar functional group C═O N-methylpyrrolidone (NMP) hinders evaporation solvent NMP, thus creating structure, which offers flexible region chain segment movement enlarging amorphous zone PVDF-HFP. From results IR Raman spectroscopy, it was found that presence induced unique ion transport channels created massive aggregated pair (AGG) contact (CIP) cluster structures composed Li+ multiple TFSI– and, at same time, effectively reduced crystallinity electrolyte, hence further contributing to diffusion. As result, rate 2 C, Li|CPE-15|LiFePO4 solid-state battery delivers an initial discharge-specific capacity 134.9 mAh g–1 maintains stability retention 84% during 400 charge–discharge cycles while Li|CPE-0|LiFePO4 fails after only few rate.
