The porous Co(OH)₂ was synthesized with SDS(Sodium dodecyl Sulfate) as the soft template and urea as the hydrolysis agent.XRD and SEM were used to characterize the synthesized porous Co(OH)₂,which possesse a layered structure with a pore-size of 20~30 nm.All electrochemical tests show that the porous Co(OH)₂ has a good capacity due to its unique porous structure and a high surface area of 283 m²/g.The highest specific capacitance of 320 F/g was obtained for the as-prepared Co(OH)₂ at a current density of 5×10³ A/cm².
