摘要
能源和环境问题引发能源储存技术的开发,而超级电容器因功率密度大、充放电速度快和循环稳定性好成为了一种新型储能装置,但是其较低的能量密度限制了它的广泛应用。镍基材料因具有高理论容量而被广泛研究,但稳定性差、工作电压窗口低限制了该类材料的能量密度和功率密度。根据化学成分将镍基材料分为五类,以近年来镍基材料的研究进展,探讨这些材料的结构与其电化学性能的关系,以及镍基材料在超级电容器应用中所面临的挑战和机遇。
Energy and environmental problems lead to the development of energy storage technology,and the super-capacitor has become a new type of energy storage device due to its high power density,fast charging and discharging speed and good cycle stability,but its low energy density limits its wide application.Nick⁃el-based electrode materials have been widely studied because of their high theoretical capacity.However,poor stability and low operating voltage window limit the energy density and power density of the materials.Nickel-based materials are divided into five categories according to their chemical composition in this paper,and the research progress of nickel-based materials in recent years is briefly introduced.The relationship between the structure of these materials and their electrochemical properties is discussed,The challenges and opportunities in the application of nickel-based materials in super-capacitors are presented.
