Ni(OH)2@CoMnO3 hierarchical nanosheets grown on carbon cloth for high-performance supercapacitor

Ni(OH)2@CoMnO3 hierarchical nanosheets were prepared on carbon cloth using a two-step hydrothermal method. The integration of large Ni(OH)2 nanosheets with the smaller CoMnO3 nanosheets significantly improved the electrochemical performance. The composite material, Ni(OH)2@CoMnO3, exhibited significantly enhanced specific capacitance (3068F/g at 1 A/g) and remarkable cycling stability compared to its individual components, CoMnO3 and Ni(OH)2, making it a promising electrode material for electrochemical energy storage applications.
