摘要
由于具有丰富资源和可期的成本优势,钠离子电池已成为大规模储能电池领域的研究热点.类似于锂离子电池负极,碳材料是研究最为广泛的储钠负极材料.然而碳材料的种类繁多,且不同处理条件下其结构也多样,从而造成储钠性能的差异,甚至产生有争议的储钠机制.为了梳理碳结构与其储钠反应行为的关系,本文综合分析了不同种类碳材料的结构特征及储钠行为,讨论了可能存在的电化学机理,对一些尚存争议的地方提出可能的辨析途径,为发展高性能碳基储钠材料提供借鉴思路.
Because of its rich resources and cost advantages, sodium-ion battery has attracted increasing attention in the field of large-scale energy storage. Similar to the lithium-ion battery anode, carbon materials are the most widely studied sodium storage anode materials. However, carbon materials have diverse structures relied on the treatment conditions, resulting in differences in the properties of sodium storage and even the different sodium storage mechanisms. In order to study the relationship between the carbon structure and its storage behavior, this paper comprehensively analyzes the structural characteristics and sodium storage behavior of different carbon materials, discusses the possible electrochemical mechanism, and makes possible analysis of some existing controversial areas. And this paper can also provide a reference for the development of high performance carbon-based sodium storage materials.
