Preparation of all-solid supercapacitor based on polyaniline and Nafion

Two different symmetric supercapacitors with polyaniline as active electrode materialwere prepared. One supercapacitorwas consistedof polyaniline applied onto Pt foil and immersed in hydrochloride acid electrolyte, and the other was consisted ofthe polyaniline casted toa carbon cloth current collector with a solid Nafion as the electrolyte. The assembled supercapacitors were tested using cyclic voltammetryand chronopotentiometry. Results showed that the supercapacitor with liquid electrolyte has slightly higher value of specific capacitance compared to supercapacitor with the Nafion membrane, but the latest showed that Nafion can be used as solid electrolyte as well as that the Nafion provides protons and counter ions essential for polyaniline conductivity. With the Nafion membrane the flexible supercapacitor was constructed and good cycling stability was achieved
