Polymer-based solid electrolyte for energy storage applications Sarah Asiri , Emre Cevik, Ayhan Bozkurt Department of Biophysics, Energy Research Unit, Imam Abdulrahman Bin Faisal University, Saudi Arabia In the flexible energy storage systems, Organohydrogel Polymer Electrolytes (OHEs) are attracting huge attention due to their cost-effectiveness, inherent safety, flexibility, stability, size and adaptability through system integration [1] . The OHEs are supposed to avail more safety by preventing leakage of harmful electrolytes from the batteries during transport and use [2]. In this study, Organohydrogel Polymer Electrolyte was prepared via cross-linking Glycerol-Agarose and with ZnSO4&ZnAce salts (Gly-Agr-ZnSO4&ZnAce) to apply it in Solid Zinc Battery (sZB). The optimized polymer electrolyte allows stable cycling of the sZB, which is made possible by a high ionic conductivity and a high positive zinc-ion species transference number. The high results of the electrochemical measurements and cyclic voltammetry show the ability of sZB to work in both low- and high-temperature conditions is a result of the high thermal stability of hydrogel polymers, which is essential for the applications of energy storage in challenging environments.
