Abstract

We report the synthesis of CuFe₂O₄-Fe₂O₃ composite material for efficient and highly stable supercapacitor electrode by using eco-friendly lowerature co-precipitation method. The CuFe₂O₄-Fe₂O₃ composite demonstrated the highest specific capacitance of 638.24 F g^-1 and excellent stability up to 2000 charge/discharge cycles. The achieved capacitance value is 16 times higher than that of pure CuFe₂O₄. The results revealed the extraordinary performance of CuFe₂O₄-Fe₂O₃ composite as supercapacitor electrode with excellent retention in comparison to CuFe₂O₄. The enhanced electrochemical activity of CuFe₂O₄-Fe₂O₃ composite is attributed to the synergistic effect which is responsible for redox coupling between Cu²⁺ and Fe³⁺ that has never been achieved by single component before.
