High ionic conductivity of a flexible solid-state composite electrolyte for a lithium-ion battery

A solid composite electrolyte (PLC SCE) with PEG/PEO/LATP/CNF enhances Li-ion conductivity (1.31 × 10 −4 S cm −1 at 30 °C) and prevents dendrite growth. A symmetrical Li-ion battery with PLC SCE remains stable for 300 hours, even under stress.
