摘　　要：过高的煅烧温度限制了氯化镍(NiCl_(2))在热电池正极材料中的应用。本研究通过在原料中引入添加剂氯化亚铜(CuCl),在300℃的煅烧温度下实现了NiCl_(2)的低温制备,所得产物为NiCl_(2)与CuCl的复合物(NiCl_(2)@CuCl),具有良好的结晶度,其微观形貌为由若干片状组织镶嵌而形成的棒状结构。X射线光电子能谱表明NiCl_(2)@CuCl中存在异质结,有利于增强其电化学性能。NiCl_(2)@CuCl还具备良好的热稳定性。本研究为过渡金属卤化物的低温除水/低温制备提供了一种新的策略。The excessive calcination temperature limits the application of nickel chloride(NiCl_(2))in the cathode material for thermal battery.The low-temperature preparation of NiCl_(2)was achieved at a calcination temperature of 300℃via introducing the additive cuprous chloride(CuCl)into the raw material,resulting in a composite of NiCl_(2)and CuCl(NiCl_(2)@CuCl).NiCl_(2)@CuCl possessed good crystallinity and its morphology was the rod-shaped structure formed by embedding several sheet-like structures.X-ray photoelectron spectroscopy indicated that the presence of heterojunction in NiCl_(2)@CuCl,which was beneficial for enhancing its electrochemical performance.NiCl_(2)@CuCl was also equipped with remarkable thermal stability.This research provided a new strategy for the low-temperature dehydration/low-temperature preparation of transition metal halides.
