An increasing demand for flexible, lightweight and low cost energy storage devices with high energy and power densities in different applications has motivated extensive research and development of different types of batteries and supercapacitors. A novel thin film energy storage device based on the ionic polymer metal composite configuration is presented, fabricated and tested in order to evaluate and compare it with current requirements for the energy storage needs. Different configurations of Ionic polymer-metal composite were fabricated and tested; the one showing the best charge-discharge performance was selected and more extensive tests and characterizations were carried out. The results have shown excellent performance for the chosen Sodium cation based configuration of energy storage. Finally, self powered systems based on the integration of polymer solar cells and the proposed energy storage device were tested, showing their appropriate integration. Several different applications of self powered systems are also presented.
