文摘 硅作为一种极具潜力的锂离子电池负极材料,已引起研究者的广泛关注。然而硅材料储锂过程中伴随着巨大的体积变化,导致电极/电解液界面不稳定,是限制硅电极商业化的主要因素之一。深入了解硅负极的界面反应机理,有助于改善硅负极的界面性质,进而提高硅负极的电化学性能。本文综述了硅负极界面反应的演化机制,包括Li-Si合金化过程、硅表面氧化硅的反应和表面纯化膜的形成,并讨论了其对硅电化学性能的影响。
其他语种文摘 As an attractive candidate for anode materials,silicon has attracted extensive attention.The instability of electrode/electrolyte interphase due to the inherent volume variation upon(de)lithiation is one of the major factors that limit the commercialization of Si materials.The in-depth understanding of the interface reaction of Si is helpful to modify the interface properties of Si,and further improve the electrochemical performance.This review summarizes the research on the interface reaction mechanism of Si during(de)lithiation process,including Li-Si alloying process,the reactions of primary oxide layer and the formation of passivation film on the Si surface.Moreover,the effect of the three processes on the Si electrochemical performance are also discussed.
