چکیده انگلیسی
Nanostructured spinel NiMn2O4 arrays have been fabricated by a facile hydrothermal approach and further investigated as binder-free electrode for high-performance supercapacitors. Compared with Mn3O4, NiMn2O4 exhibited higher specific capacitances (662.5Â FÂ gâ1 and 370.5Â FÂ gâ1 in different electrolytes at the current density of 1Â AÂ gâ1) and excellent cycling stability (~96% capacitance retention after 1000 cycles) in a three-electrode system. Such a novel microstructure grown directly on the conductive substrate provided sufficient active sites for redox reaction resulting in their enhanced electrochemical behaviors. Their improved performances suggested that ultrathin sheet-like NiMn2O4 arrays on Ni foam substrate were a promising electrode material for supercapacitors.
