摘要
目前,利用硅材料的高比容量和碳材料的稳定性制备硅碳复合负极材料是最有效的途径之一。在众多硅碳复合负极材料制备工艺中,因化学气相沉积法(CVD)制备的硅碳复合负极具有充放电效率高、循环稳定性好、对设备要求较低、适合工业化生产等优势,受到了广泛关注。综述了CVD法制备硅碳复合负极材料的研究进展,从硅碳复合材料结构角度,如核壳结构、蛋黄壳结构、多孔结构和嵌入式结构,对不同结构类型的硅碳复合负极材料结构设计及电池性能等方面进行介绍,同时阐述了各自优势以及存在的问题。最后介绍了CVD法制备硅碳复合负极材料应用进展,并对硅碳复合负极材料产业化进行了展望。
At present,it is one of the most effective ways to prepare silicon-carbon composite anode materials by compositing the silicon materials with high specific capacity and the carbon materials with stability.Among the many preparation processes of silicon-carbon composite anode materials,the silicon-carbon composite anode prepared by chemical vapor deposition(CVD)has the advantages of high charging/discharging efficiency,good cycle stability,facile process,and is suitable for mass production.This paper summarized the research progress of preparing silicon-carbon composite anode materials by chemical vapor deposition.From the perspective of silicon-carbon composites structure,such as coreshell structure,yolk-shell structure,porous structure,and embedded structure,the structural design and battery performance of different types of silicon-carbon composite anode materials were introduced,and their advantages and existing the problem were discussed.Finally,the application of silicon-carbon composite anode materials prepared by CVD was summarized,and we prospected the future of industrialization of silicon-carbon composite anode materials.
