摘要 概述了多孔硅基负极材料在锂离子电池中的应用,重点介绍了材料结构和复合方式对其电化学性能的影响;分析了导致其循环性能降低的主要原因,指出控制电池循环过程中硅基材料体积变化、抑制SEI膜的增加是改善硅基负极材料循环性能的重要途径.对多孔硅基复合负极材料的研究进行了展望,提出在纳米化和复合化的基础上,设计特殊孔道结构、制备多孔的硅/碳复合材料是推进硅基负极材料应用的重要研究方向. Research progress in porous silicon-based anode materials for Li-ion batteries was reviewed, focusing on the effects of their morphology and compound on the electrochemical properties. The reasons of poor cycling performance are analyzed. It is pointed out that to control the huge volume change and SEI growth during the cycling is an effective way for improvement of the performance. Outlook for the future development of porous silicon composite anode materials and further research of designing porous structure based silicon nanocomposites for the application of silicon anodes are finally outlined.
