SHANMUGAVADIVEL, M.; SUBRAMANIAN, M.  and  DHAYABARAN, V.. High Power and Long Cycling Stability Supercapacitor Based on PANI/Mn₂CoO₄ Nanohybrid. Port. Electrochim. Acta [online]. 2025, vol.43, n.4, pp.237-248.  Epub Aug 31, 2025. ISSN 0872-1904.  https://doi.org/10.4152/pea.2025430403.

Nano-sized PANI/Mn2CoO4 hybrid was successfully synthesized by diluted polymerization method, for high power SC. The metal oxide incorporation significantly increased the polymer’s crystallinity and electrochemical efficiency. PANI/Mn2CoO4 electrochemical evaluation showed enhanced energy, power density (2.28 and 762.6 W/kg-1, respectively), specific capacitance (470 Fg-1) and columbic efficiency of 87.1%, with long cycling stability up to 1000 cycles. NHP improved capacitive nature and power characteristics were achieved by the synergistic effect between PANI and Mn2CoO4.

Keywords : charge-discharge; energy storage; PANI/Mn₂CoO₄; SC.
