Electrical energy storage and utilization has become a primary focus of the world energy community. There has been a great interest in developing and modifying energy storage devices. Supercapacitor is one such device that has emerged with the potential to meet the current energy demands. Supercapacitors are electrochemical double layer capacitors, intermediate energy systems between batteries and conventional dielectric capacitors. Despite greater capacitances than conventional capacitors, supercapacitors have yet to match the energy densities of batteries and fuel cells. This presentation reports the applicability of polymerizable ionic liquids as the promising advanced materials towards optimizing the performance of supercapacitors. Carbon nanotube based polymer films are prepared by insitu-polymerization of ionic liquid monomers and these plastics are used to build the solid state electrochemical supercapacitor. Supercapacitor performance was characterized by charge-discharge cycles and impedance spectroscopy.
