Abstract

A Polyaniline‐Supercapacitor with quinone electrolytes remains stable over 50 000 galvanostatic charge‐discharge cycles. The quinones provide superior stability by preventing the conversion of porous polyaniline to a highly reactive state. Our work shows that highly stable polymer‐supercapacitors can be engineered by combining electrochemically active polymers and redox‐active electrolytes with concerted electrochemical properties
