The manganese oxide (MnO2) nanowires and cobalt hydroxide (Co(OH)(2)) nanosheets are successfully electrodeposited on nickel foam (NF), respectively (referred to as MnO2/NF and Co(OH)(2)/NF electrode hereinafter). Both electrodes show higher specific capacitance (C (s)) and more excellent rate performance than that of most reported corresponding materials. In addition, our previous study of Ni(OH)(2)/NF electrodes also exhibited conspicuous results. Combined with the outstanding properties of NF, it is noticeable that the NF electrodes may be a promising choice for supercapacitors.
