摘要
传统的沥青碳包覆石墨负极材料已经无法满足市场对锂离子电池在能量密度、充电、安全性等方面提出的更高要求,而氮元素掺杂可以调控碳包覆层的界面结构,提升负极材料的电化学性能,受到广泛关注和研究,且氮掺杂碳包覆是在当前的负极材料产业链条件下最具潜力和最容易实现产业化的改性方式之一。因此,本文从氮掺杂碳的结构特征及氮掺杂碳包覆负极材料两方面进行了综述,并对氮掺杂碳包覆的未来进行了展望,以期为其产业化发展提供参考。
The traditional asphalt carbon-coated graphite anode materials cannot meet the higher requirements of the market for lithium-ion batteries in terms of energy density,charging,safety,etc.,while nitrogen doping can regulate the interface structure of the carbon coating and improve the electrochemical performance of the material,which has received widespread attention and research,and nitrogen doped carbon coating is one of the easiest modification methods to achieve industrialization under current negative electrode material industry chain.Therefore,the structural characteristics of nitrogen-doped carbon and nitrogen-doped carbon coating anode materials are reviewed in this paper,and the future of nitrogen-doped carbon coating is prospected,in order to provide reference for its industrial development.
