水热法氧化镍氧化铜比容量Hydrothermal Method Nickle Oxide Copper Oxide Specific Capacity


本文以氯化铜和氯化镍为原料,通过与氢氧化钠化学反应制备出氢氧化铜和氢氧化镍的混合沉淀,然后转入高压反应釜,最后再高温煅烧制备出氧化镍/氧化铜复合材料,通过XRD、SEM对复合材料的物相进行分析,并用循环伏安、交流阻抗和恒流充放电对制备的复合材料进行电化学性能分析。结果表明:150℃30 h的水热条件下,氧化镍/氧化铜复合材料的电化学性能最佳,1 F∙g−1电流密度下的比容量达到200 F∙g−1。

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.
