摘要：

Cubic CoMn2O4 particles directly grown on Ni foam are developed for asymmetric supercapacitors via a simple hydrothermal method. During electrochemical study, CoMn2O4 electrode exhibits a high capacity of 140.6 mAh g( 1) at 1 mA cm (2). A asymmetric supercapacitor containing CoMn2O4 electrode demonstrates a high capacitance of 77.8 F g (1) at 2 mA cm (2). The electrode developed has good potential for practical applications in asymmetric supercapacitors. (C) 2018 Elsevier B.V. All rights reserved.
