Characteristics of the citrate-based zinc-polyaniline secondary cell with supercapattery behaviour

The electrochemical characteristics of zinc-polyaniline (PANI) secondary cell in the electrolyte containing 0.8 M Na citrate, 0.3 M NH4Cl and 0.3 M ZnCl2 is investigated. Based on the measurements of potentials and voltage of the cell during charge/discharge for the currents in the range of 18 to 45 mA, the specific electrode capacity of 85 to 55 mA h g(-1), the specific energy of 60-40 mW h g(-1) and the specific power of 150-350 mW g(-1), is determined. Keywords: polyaniline; zinc; batteries; pseudocapacitors; citrates.
