The present work reports synthesis of cobalt hydroxide (Co(OH)(2)) rods on nickel foam and its supercapacitor application. Hierarchical Co(OH)(2) rods with length of approximately 3.5m and diameter of approximately 400nm were prepared by one-step, simple, and inexpensive chemical-bath-deposition method. The direct growth of Co(OH)(2) rods on the Ni foam gave three dimensional (3D) structure for easy access of electrolyte throughout material surface. Also, well-adhered interface between Co(OH)(2) rods and Ni-foam surface gave better conduction channels. Detailed electrochemical study was performed by using cyclic voltammetry and galvanostatic charge/discharge measurements. The results demonstrate that Co(OH)(2) rods on Ni foam are efficient electrodes for supercapacitor application.
