Abstract

Using bimetallic oxide as the electrode material of supercapacitor is emerging as a promising approach to supply better pseudocapacitive performance than that from the electrodes made of corresponding single metal oxides. Herein, Ni-Mn bimetallic oxide nanosheets (Ni-MnBMO) on carbon cloth substrate were synthesized through a facile hydrothermal method. With the help of cyclic voltammetry activation process, the prepared A-Ni-MnBMO electrode exhibits the maximum specific capacitance 574 F g?1 (within a potential range of ?0.2
