Unveiling the Interfacial Dynamics of Crosslinked Biodegradable Polycaprolactone Solid Polymer Electrolytes and Li Metal During Lithium Plating and Stripping via Operando ATR‐FTIR Spectroscopy
ABSTRACT Polycaprolactones (PCL) have gained attention as a biodegradable and environmentally sustainable solid polymer electrolyte (SPE) for solid‐state battery applications. While poly(ethylene oxide) (PEO) systems are widely studied, the interfacial mechanisms of PCL‐based SPEs in contact with Li metal remain insuff...
