Preparation and Characterization of Poly(1-vinylpyrroli done-co-vinyl acetate)/Poly(methyl methacrylate) Polymer Electrolyte based on TPAI and KI

Polymer electrolytes are promising materials for electrochemical device applications, such as , high energy density rechargeable batteries, supercapacitors, fuel cells, electrochromic displays, etc. Polymer blend electrolytes based on (PVP-co-VAc) and ( PMMA) with different weight ratio of Tetra propyl ammonium iodide (TPAI) and Potassium iodide (KI), salts using DMSO as solvent. The gel electrolytes were prepared by solution cast technique. More details can be found in the full paper.
