摘要	CoMn layered double hydroxides (CoMn-LDH) are promising electrode materials for supercapacitors because of their excellent cyclic stability. However, they possess relatively low capacitances. In this work, hybrid CoMn-LDH@MnO2 products grown on Ni foams were obtained through a facile hydrothermal method. The as-synthesized samples employed as electrodes deliver a specific capacitance of 2325.01 F g(-1) at 1 A g(-1). An assembled asymmetric supercapacitor using these products as positive electrodes shows a maximum energy density of 59.73 W h kg(-1) at 100 0.09 W kg(-1). The prominent electrochemical performance of the as-prepared electrodes could be attributes to hierarchical structures. These findings suggest that hybrid structures might be potential alternatives for future flexible energy storage devices.
