Highly conducting ionic liquid doped polymer electrolyte for energy storage applications

The main aim of the present work is to optimize highly conducting solid polymer electrolyte by doping of ionic liquid in Poly-ethylene oxide (PEO) polymer complexed Sodium Iodide (NaI) matrix. Solution casting method has been used to synthesis solid polymer electrolyte. Electrical, thermal, structural, and optical studies confirm the homogenous complexation of polymer electrolyte with ionic liquid. Furthermore, the electric double-layer capacitors (EDLCs) device and Dye Sensitized Solar Cell (DSSC) has been developed using high conducting ionic liquid (IL) polymer electrolyte with maximum conductivity, demonstrating that ionic liquids have a potential possibility to choose as electrolyte in developed energy devices.
