Impact of Hydrothermal Conditions on Copper-Nickel-Micron Composite Ultra Capacitor Specific Capacity
Abstract: Nickel oxide/copper oxide composites are prepared by using cupric chloride and nickel chloride as raw material by chemical reaction with sodium hydroxide to prepare copper hydroxide and nickle hydroxide precipitation which then transferred into autoclave, and calcined. The as- prepared composites were well analyzed by XRD and SEM and the electrochemical performance was investigated by cyclic voltametry, AC impedance and galvanostatic charge-discharge. The re-sults show that under the condition of 150˚C 30 h, the electrochemical performance is the best. The specific capacitance was 200 F∙g−1 at the charge-discharge current of 1 A∙g−1.
