The electrochemical and thermal properties of non-flammable polymer gel electrolyte (NPGE) have been studied to examine its potential application as an electrolyte in lithium ion batteries. Diphenyl phosphite (DPP) was used as a fire retardant component of NPGE. The electrochemical studies showed that NPGE has high ionic conductivity of 0.9 mS cm⁻¹ at 30°C and a wide electrochemical window of ca. 4 V vs. Li/Li⁺, which are suitable for a practical battery system. Good thermal properties are confirmed by thermal safety calorimetry (TSC) measurements.
