Study on carbon negative electrode for lithium ion batteries

Abstract

综述了目前常用的锂离子碳负极材料的研究概况,并且按碳材料的石墨化程度不同对其进行分类,具体阐述了多种锂离子电池碳负极材料的特点及其制备方法。同时还简述了锂离子在碳材料中的几种嵌入机理,综合讨论了这几种嵌入机理的优缺点。通过对碳材料的循环伏安性质、充放电性质、电容量、可逆性及结构特征的比较,介绍了不同结构的锂离子电池碳负极材料的嵌锂特性。This paper reviews the research status of all kinds of carbon materials for lithium ion batteries in the present.The properties and the producing ways of carbon materials for lithium ion batteries are described in this paper according to their graphitization degrees.By the way,it also outlines several mechanisms for lithium insertion in the carbon materials,and comprehensively discusses the excellance and problems of these mechanisms.Through comparing the variation in performance of cyclic voltammetric and charge discharge processes,the character for capacity,reversibility and structure of carbon materials with each other,it introduces the lithium intercalation characteristics in carbon anode materials for lithium ion batteries with different structure.国家自然科学基
