Abstract

Super capacitor is an important device for energy storage and usage with high power and high efficiency. Commercial super capacitors are typically fabricated by using binder to attach electrode powder to the metal foil current collector. In this paper, we present a method to fabricate super capacitors using binder-free electrodes and carbon current collector to enhance the compact size, light weight and flexibility. To obtain high power and high energy density, nano composite electrode of CNTs-polyaniline was employed. The super capacitors with PVA electrolyte achieved the electrode capacitance of 170 F/g and charged voltage can be up to 1.2 volt, which is the maximum voltage achieved by aqueous PVA electrolyte.
