Lithium batteries have gained significant attention due to their high energy density, specific capacity, operating voltage, slow self-discharge rate, good cycle stability, and rapid charging capabilities. However, the use of liquid electrolytes presents several safety hazards. Solid-state polymer (SPEs) offer a promising alternative mitigate these issues. This study focuses on preparation an ionically conductive electrospun membrane its potential application as SPE. To support circular approach reduce environmental impact, target polymeric formulation combines poly(ethylene oxide) (PEO) lignin, sourced from paper industry waste. The is optimised ensure dissolution lithium salts enhance integrity. addition lignin crucial contrast dendrites' growth prevent consequent battery breakdown. electrospinning process adjusted obtain stable, homogeneous nanofibrous membranes, which are characterised using electron scanning microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential calorimetry (DSC), thermal gravimetric analysis (TGA). membranes' SPE assessed by measuring ionic conductivity (>10-5 S cm-1 above 50 °C) anodic stability (≈4.6 V vs. Li/Li+), testing compatibility with metal reversible cycling in symmetric Li|Li cell at 55 °C.
