Abstract

Battery technology serves as the primary energy storage system in the modern world. The global market share of Li-ion batteries (LIBs) has rapidly increased due to the demand in day-to-day life, which has attracted the scientific community towards this research area. Polymer electrolytes (PEs) are a key component of LIBs, which are categorized into three types: solid polymer electrolytes (SPEs), gel polymer electrolytes (GPEs), and composite polymer electrolytes (CPEs). When these PEs are integrated into batteries with inorganic fillers, ionic liquid (IL), nanomaterials, and plasticizers, they enhance the electrochemical stability window, ionic conductivity, transport number, and mechanical robustness of PEs. The choice of PEs in batteries depends on the selection criteria of polymer host types, such as PEO, PVDF, PVA, PMMA, PVP, PAN, and chitosan, as well as metal salts, including LiClO4, LiTFSI, LiPF6, LiBF4, and LiBOB, are discussed. This review presents a detailed study of SPEs, GPEs, and CPEs, examining their performance in terms of ionic conductivity and transport number, to improve the efficiency and safety of LIBs.
