Abstract

Due to their increased safety and energy density, solid-state lithium batteries (SSLBs) are expected to power upcoming electric vehicles and smart grids. However, these batteries face significant challenges due to their relatively low ionic conductivity at room temperature and high electrolyte-electrode interfacial resistance. A practical method for increasing the solid polymer electrolytes' ionic conductivity at room temperature is the preparation of polymer-in-salt solid electrolytes (PISSEs) with lithium salt contents greater than 50% by weight. This method is also suitable for scalable production. In this paper, a broad overview of solid-state polymer electrolytes was presented, along with information on their historical development, optimum polymer needs, and their benefits. Similarly, the structure and ionic conductivity mechanism of polymer-in-salt solid electrolytes were explained by analyzing the interactions between lithium salt and the polymer matrix. The classification of solid-state polymer electrolytes was then discussed, along with the most recent developments in polymer-in-salt solid electrolytes (PISSEs) made from polyacrylonitrile (PAN), polycarbonate derivatives, polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP), and polyethylene oxide (PEO). Finally, a suggestion for potential improvements to the manufacturing of solid polymer Li-ion battery electrolytes that are stable and affordable was made.
