摘　　要：过渡金属特别是镍和钴元素以其优异的电化学性能和丰富的自然资源在储能电极材料的研究和开发中得到了广泛的应用,其中,镍钴层状双氢氧化物(NiCo-LDH)电极材料因形貌易调控和高比电容等优点而备受关注。对NiCo-LDH超级电容器材料的制备方法和材料改性(离子掺杂和材料复合)进行综述,讨论了制备方法对材料微观结构及其电化学性能的影响。Transition metals,especially Ni and Co elements,have been widely investigated and applied in developing energy storage electrode materials due to their excellent electrochemical properties and abundant natural resources.Among them,NiCo-layered double hydroxide(NiCo-LDH)electrode material attracted much attention because of its merits,such as tunable morphology and high specific capacitance.Herein,we reviewed the preparation methods of NiCo-LDH as a supercapacitor material and its modified materials via ion-doping and hybrid combination.The effects of the preparation method on its microstructure and electrochemical performance were discussed.
