Abstract

This review explores the principles, materials, highlights and challenges related to Polymer Blend Electrolytes (PBEs). The fundamentals of miscible and immiscible polymer blends (PBs) are discussed, along with how to foresee blend compatibility using thermodynamic models such as the Gibbs free energy theory. Measurement approaches for understanding ionic transport phenomena in PBEs are also considered, including the Arrhenius and Vogel Tamman Fulcher (VTF) models, to ascertain the effects of factors including morphology and intermolecular impacts on the ionic conductivity of blends. PBEs have good potential to fulfil various functional requirements in fuel cells, batteries, supercapacitors, and other applications. Further research and development efforts focused on enhancing blend composition and resolving technical difficulties would result in more efficient and sustainable energy storage innovations.
