Electrochemical Characteristics of “Polyaniline” Cathodes and Anodes in Aqueous Electrolytes

Abstract

The quinoid-benzenoid-diimine form, (=(C₆H₄)=N-(C₆H₄)-N=)_x of “polyaniline” shows excellent cathode characteristics including recyclability when used in conjunction with a zinc anode in an aqueous electrolyte of (l. 0M ZnCl₂ + 0. 5M NH₄Cl) having a pH of ∼ 4. The reduced form of this material, (-(C₆H₄)-N(H)-(C₆H₄)-N(H)-)_x can be used as an anode in conjunction with a Pb0₂ cathode in an aqueous 0.5M Pb(BF₄)₂ electrolyte.
