Abstract

In this work, biobased membranes were developed for potential application as gel polymer electrolytes (GPEs) for potassium ion batteries (KIBs). The proposed membranes were crosslinked via ring-opening reaction of a cardanol-derived epoxy resin with glutaric, succinic and hexahydro-4-methylphthalic anhy-dride. The curing time and temperature and the reaction kinetic were studied by non-isothermal differential scanning calorimetry. Gravimetric gel content measurements and dynamic mechanical thermal analysis confirmed the high-network connectivity of such biobased membranes.The electrochemical characteriza-tion perfomed on such systems reported excellent swelling performances, electrochemical stability towards potassium metal and suitable ionic conductivity (10‒3 S cm‒1 ) at room temperature.
