摘要
锂离子电容电池兼具锂离子电池和超级电容器的优势,凭借高能量密度、高功率密度、长循环寿命和快速充放电等优势成为具有前景的新型储能系统。然而,电池型电极和电容型电极之间的动力学不平衡、能量密度不太理想和循环稳定性较差等关键问题仍然存在,若要有效解决该问题需要在该领域开发出新型正负极电极材料。因此,本文详细介绍了锂离子电容电池正负极材料(例如金属氧化物、碳材料、硫化物等)的研究进展以及技术路线,并针对目前存在的问题进行了分析,同时对电极材料未来的研究方向进行了展望,以及对其他化学电源的研究提供了新思路和手段。
With the advantages of both lithium ion battery and supercapacitor,lithium ion capacitor battery has become a promising new energy storage system with its advantages of high energy density,high power density,long cycle life and fast charging and discharging.However,some key problems still exist,such as dynamic imbalance,less ideal energy density and poor cycling stability between battery electrode and capacitor electrode.The electrode material is an important part of the battery and seriously affects the overall electrochemical performance.To solve this problem effectively,a variety of new type of anode and cathode electrode materials should be developed in this field.Therefore,this paper introduces in detail the research progress and technical route of cathode(layered metal oxides,graphene composite anode and other novel cathode materials)and anode(transition metal oxides,carbon materials,lithium compounds and sulfides)materials for lithium ion capacitor batteries,and analyzes the existing problems.It is found that the properties of electrode materials can be improved by nano treatment,material coating and heteroatomic doping.At the same time,the future research direction of electrode materials is prospected,and new ideas and means are provided for the research of other chemical power sources.
