摘要:

锡锑(SnSb)合金材料具有高理论容量、高电导率、低反应电位等优点,是当前研究最为广泛的锂/钠离子电池负极材料之一。然而,SnSb合金负极材料在嵌脱金属离子过程中巨大的体积效应导致电极材料粉化失活,从而导致其循环性能不尽人意。为了解决上述问题,从结构设计、碳复合材料、三元合金等方面介绍近些年的研究进展,分析现有合成策略的设计方法和作用机理,最后提出SnSb合金负极材料在未来研究中的发展方向。

Abstract:

Tin-antimony(SnSb) alloy materials have various advantages, such as, high theoretical capacity, high conductivity, and low reaction potential, which make SnSb alloy one of the most widely studied anode materials for lithium/sodium ion batteries. However, the huge volume variation of SnSb alloy anode material upon cycling leads to pulverization of the electrode material, which results in unsatisfactory cycling performance. In order to solve these issues, the research progress in recent years is introduced from the aspects of structural design, carbon composition, ternary alloys, modification of electrolytes and current collector. The synthsis routes and mechanisms of existing synthesis strategies are analyzed. Finally, the development direction of SnSb alloy anode materials in future research is proposed.

Key words: Tin-antimony alloy, lithium-ion battery, sodium-ion battery, anode material
