Development of PANI/CuMn2O4 nanocomposite via hydrothermal method for supercapacitor applications

CuMn2O4 is commonly selected as electrode material in supercapacitors owing to its cost-effectiveness and favorable performance as a binary transition metal oxide. The limited energy density of binary metal oxides restricts their widespread use as supercapacitors, thereby highlighting the need to develop a supercapacitor structure based on CuMn2O4. This study aims to enhance the electrochemical performance of CuMn2O4 and polyaniline (PANI) by exploiting their complementary characteristics through their coupling. Various physiochemical instruments were utilized to investigate the physical properties of synthesized nanomaterials. Specific capacitance (Cs) of PANI/CuMn2O4 composite electrode was determined to be 1181 F g−1 when tested at a 1 A g−1. Additionally, the cycle retention capacity of the supercapacitor was found to be 95
