Effect of TiO₂ Nanoparticle on PEMA-Based Solid Polymer Electrolyte

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 4.65x10(-5) S cm(-1) when measured using the LC method. After adding CNT, the conductivity of this sample reaches 2.95x10(-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.
