PURPOSE:To provide a high charge/discharge capacity with long lifetime secured while elusion of polyaniline from the electrode and its wet swell are prevented in the case where the electrode is used being built in an electrochemical cell of a secondary battled, etc. CONSTITUTION:Dedoped polyaniline is doped with highpolymer sulfonic acid, wherein the condition is such that 2<=N/S<=40. where N/S is mol ratio of nitrogen atom in polyaniline to the sulphur atom in sulfonic radical in the highpolymer, and therefrom an electrode electrochemically active is fabricated, and an electrochemical cell of a secondary battery, etc., using this as a positive electrode is accomplished. |
