Abstract

We demonstrate optimized supercapacitive characteristics of electrodeposited polyaniline by adding organic salt into elec-trolyte. The optimum amount of the organic salt is found to be 2 wt % which provides better ionic conductivity of the electrolyte,leading to the improved specific capacitance of 259 Fg21. This capacitance remains at up to 208 Fg21(80% capacity retention) after1000 charge-discharge cycles. The optimized organic salt added electrolyte causes better rate performance and higher cyclability. Sig-nificantly reduced electrochemical charge transfer resistance at the electrode/electrolyte interface results in the increased ionic conduc-tivity, which can be useful in electrochemically preferred power devices for better applicability.
