| description | The persistent emphasis on safety issues in lithium-ion batteries (LIBs) with organic liquid electrolytes revolves around thermal runaway and dendrite formation. The high thermal stability and non-leakage properties of polymer electrolytes (PEs) make them attractive as next-generation electrolytes for LIBs. This study presents a blended terpolymer electrolyte (BTPE) membrane, integrating the high ionic conductivity of dual ion conducting polymer electrolytes (DICPEs) with the elevated lithium transference number (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mrow><mi>t</mi></mrow><mrow><mo>+</mo></mrow></msub></mrow></semantics></math></inline-formula>) of single-ion conducting polymer electrolytes (SICPEs). The BTPE was synthesized by blending PAA–PVA with lithiated acrylic acid (LiAA), lithiated 2–acrylamido–2–methylpropane sulfonic acid (LiAMPS), and a 2–hydroxyethyl methacrylate (HEMA)–based terpolymer, using lithium bis(fluorosulfonyl)imide (LiFSI) as the lithium salt. The synthesized BTPE showed excellent physical and electrochemical stability; it also exhibited an enhanced lithium transference number (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mrow><mi>t</mi></mrow><mrow><mo>+</mo></mrow></msub></mrow></semantics></math></inline-formula> = 0.47) and high ionic conductivity (5.21 × 10<sup>−4</sup> S cm<sup>−1</sup> at 30 °C), attributed to the interaction between the FSI anion and the NH group of AMPS. This research presents an innovative strategy for the design of next-generation LIB electrolytes by integrating polymer electrolytes. |
