锂离子电池负极硅碳复合材料的研究进展
Research progress on Si/C composites as anode for lithium ion batteries
摘要
Abstract
Silicon based anode materials with high specific capacity, low voltage plateau, environmental friendliness and abundant resources, are expected to replace graphite for the next generation lithium-ion batteries with high energy density. However, the conductivity of silicon is poor. Even worse, the huge volume change of Si during charge/discharge process can result in large electrochemical polarization, material pulverization, SEI film reconstitution, low coulombic efficiency and continuous capacity fading. However, silicon and carbon composites can combine their advantages of high capacity and excellent electronic conductivity, forming an anode with stable structure, good cycle stability and high capacity. This paper reviews the research progress of Si/C composite in the structural design, preparation process and electrochemical performance from the view of different dimensions of silicon (SiNPs, SiNTs/ SiNWs, SiNFs, Bulk Si), and the Si/C composite materials for future research are also prospected.关键词
