Nonetheless, enhancing the conductivity of ions of polymer electrolytes is crucial for their use in high-performance energy storage devices. This investigation proposes an innovative approach for the synthesis of P(MMA-CO-AN)-LiTFSI composite polymer electrolyte membranes exhibiting enhanced conductivity. The composite membranes synthesized in this study, specifically P (MMA-CO-AN)-LiTFSI/ Nb 2 O 5 20Wt.%, exhibit a notable porosity of ~ 62% and a liquid electrolyte uptake of ~ 249%, as anticipated. Due to low crystallinity ~ 49, thermal shrinkage, and composite polymer electrolytes (CPEs) demonstrate an impressive ionic conductivity of 3.90 × 10 − 4 S/cm at RT, along with a favourable Li⁺ transference number (0.57), electrochemical window (4.6), and low activation energy (0.30). Furthermore, the composite polymer electrolyte showcases remarkable ionic conductivity, significant electrolyte uptake, an extensive electrochemical window, low activation energy and advantageous electrolyte affinity. This promising substance is highly suitable for the development of robust and efficient electrolytes in applications for storing energy.
