摘要 本文采用一步水热法制备泡沫镍基钴镍双金属氢氧化物。通过调节Co-Ni摩尔比制备不同形貌的金属氢氧化物。并通过SEM和XRD进行了微观形貌和晶型的分析。最后将不同形貌的产物用于超级电容器电极材料,用电化学工作站进行测试分析其电化学性能。测试结果表明,当Co-Ni摩尔比为6︰4时得到的氢氧化物电化学性能最佳。 In this paper, one-step hydrothermal method was used to prepare urchin-like foam nickel-base cobalt-nickel double-metal hydroxides. Metal hydroxides with different micro-morphologies were prepared by adjusting the molar ratio of Co-Ni. The SEM and XRD were used to analyze the micro-morphology and crystal form. Finally, the products with different morphologies were used for the supercapacitor electrode material, and the electrochemical performance was tested and analyzed by an electrochemical workstation. The test results show that when the molar ratio of Co-Ni is 6 : 4, the electrochemical performance of the hydroxide is the best.
