Polyaniline is a promising material for the development of high performance flexible supercapacitor devices. However, loose structure polyaniline materials and intermolecular transport impedance between molecular chains remain significant technical barriers, particularly at loading density. In this study, we developed copper ion doped electrode (Cu-PANI@CC) on carbon cloth using simple one-step in-situ electrochemical deposition method. The properties were investigated via different testing techniques. Benefitting from catalysis regulation ions PANI chains, demonstrated relatively low internal resistance densities (> 10 mg cm-2). Moreover, had specific capacitance 3.14 F cm-2 5 mA retention 83.31% 50 cm-2. Two Cu-PANI@CC electrodes used to fabricate symmetrical capacitor, which exhibited remarkable cycling stability wide operating temperature range. excellent highlights its great potential use in high-performance
