摘要
温室气体的过量排放对全球气候产生严重不良影响,如何减少碳排放已成为全球性议题。超级电容器具有使用寿命长、功率密度高、碳排放量相对较低的优点。大力发展超级电容器储能是建立未来能源系统的可靠和有效措施。MXene材料具有优良的亲水性、电导率、高电化学稳定性和表面化学可调性,近年来在超级电容器储能应用研究领域广受关注,但MXene严重的自堆叠问题限制了其储能性能充分发挥,开发更先进的MXene材料对于下一代高性能电化学储能设备至关重要。基于此,本文综述了MXene材料在超级电容器储能应用领域的研究进展,介绍了MXene的结构和储能特性,探讨了MXene的储能机理,重点剖析了纳米工程改进MXene电极性能的结构设计,详细总结了MXene复合材料构效关系和在超级电容器应用方面的最新研究进展,最后提出了MXene材料用作超级电容器电极的研究方向和发展趋势。
Excessive emission of greenhouse gases has serious adverse effects on global climate.How to reduce carbon emissions has become a global problem.Supercapacitors have advantages of long cycle life,high power density and relatively low carbon emissions.Developing supercapacitor energy storage is an effective measure to build the reliable future energy system.In recent years,MXene materials have achievedgreat popularity in the field of supercapacitor energy storage applications due to their excellent hydrophilicity,electrical conductivity,high electrochemical stability,and surface chemical tunability.However,the serious self-stacking problem of MXene limits its performance in energy storage.Developing advanced MXene materials is critical for next generation high-performance electrochemical energy storage devices.This paper reviews the research progress of MXene material in the field of supercapacitor energy storage.Firstly,the structure and energy storage properties of MXene are introduced,followed by analysis of the energy storage mechanism of MXene.Secondly,nanoengineering of structure design to improve the performance of MXene electrode is depicted.Thirdly,structure-performance relationship of MXene composite materials and its latest research progress in application of supercapacitor are summarized.Finally,research and development trends of MXene as an electrode for supercapacitor are broadly prospected.
