Abstract

Silicon (Si) has been studied as a promising alloying type anode for lithium-ion batteries due to its high specific capacity, low operating potential and abundant resources. Nevertheless, huge volume expansion during alloying/dealloying processes and low electronic conductivity of Si anodes restrict their electrochemical performance. Thus, carbon (C) materials with special physical and chemical properties are applied in Si anodes to effectively solve these problems. This review focuses on current status in the exploration of Si/C anodes, including the lithiation mechanism and solid electrolyte interface formation, various carbon sources in Si/C anodes, such as traditional carbon sources (graphite, pitch, biomass), and novel carbon sources (MXene, graphene, MOFs-derived carbon, graphdiyne, etc.), as well as interfacial bonding modes of Si and C in the Si/C anodes. Finally, we summarize and prospect the selection of carbonaceous materials, structural design and interface control of Si/C anodes, and application of Si/C anodes in all-solid-state lithium-ion batteries and sodium-ion batteries et al. This review will help researchers in the design of novel Si/C anodes for rechargeable batteries.

可充电电池用硅/碳阳极的界面设计综述
硅(Si)由于其高比容量、低运行潜力和丰富的资源,已被研究为一种很有前途的锂离子电池合金化阳极。然而,合金化/脱合金过程中的巨大体积膨胀和硅阳极的低电子电导率限制了其电化学性能。因此,具有特殊物理和化学性质的碳(C)材料被应用于硅阳极中,以有效地解决这些问题。本文综述了Si/C阳极的探索现状,包括锂化机理和固体电解质界面的形成,Si/C阳极中的各种碳源,如传统碳源(石墨、沥青、生物质)和新型碳源(MXene、石墨烯、MOFs衍生碳、石墨烯等),以及Si和C在Si/C阳极中的界面结合模式。最后,我们对碳质材料的选择、Si/C阳极的结构设计和界面控制以及Si/C阳极在全固态锂离子电池和钠离子电池中的应用等进行了总结和展望。
