Summary:The key goals in developing electrolytes for batteries and solar panels are mechanical strength, ionic conductivity, leakage resistance, and safety. To improve ionic conductivity and mechanical strength, a PEMA‐based electrolyte with potassium iodide as salt, ethylene carbonate as plasticizer, and nanofillers is used. To make a thin polymer matrix film, a solution casting approach is used. PEMA+40% wt. KI+60% wt. EC has a maximum ionic conductivity of 4.65×10−5 S cm‐1 when measured using the LC method. After adding CNT, the conductivity of this sample reaches 2.95×10−3 S cm‐1. Scanning electron microscopy is used to analyze the surface morphology and crystallinity determined by XRD measurements. FTIR research verifies the existence of several components in solid polymer electrolyte.
