摘要: Abstract The electrochemically synthesized polypyrrole (PPy) is investigated as a possible active material of the low-cost aqueous based secondary power sources in combination with zinc, lead oxide, and sulfate. discharge capacity chloride-based electrolyte (for Zn|PPy cell) range 110 mAh g−1 PPy, while sulfate-based ∼150 mAh g−1 PPy PbSO4|PPy PPy|PbO2 cells), which close to theoretically calculated values. Electrochemical electrical parameters, reactions cells, specific capacity, capacitance, energy, power, for Zn|PPy, cells are determined. In addition, energy efficiency, considered systems estimated. Obtained values could classified battery type hybrid superacapacitors or “supercapattery”.
