锂离子电池Sb基负极材料研究进展

Sb基材料作为一类合金机制的锂离子电池负极材料,因具有比容量高、安全性好等优点受到广泛关注。 然而,由于Sb基负极材料在充放电过程中的体积效应和本身导电性较差等问题导致的循环性能不理想,制约了其作为锂离子电池负极材料的商业化应用。 本文综述了近年来在锂离子电池Sb基各类负极材料方面的研究进展,重点介绍了它们的反应机理、合成方法及电化学性能,并对Sb基负极材料的发展方向进行了展望。

Research Progress of Antimony-Based Anode Materials for Lithium Ion Batteries

As the typical anode material for lithium batteries, antimony-based materials have attracted much attention due to their high theoretical specific capacity and high safety performance. Nevertheless, antimony-based materials suffer significant capacity fading due to their large volume expansion in the charge-discharge process and poor electrical conductivity, which severely hinders their commercial applications in lithium batteries. The research progress of antimony-based anode materials in recent years is presented in this paper. Reaction mechanism, synthetic method and electrochemical performance are introduced and the research trend of antimony-based anode materials is prospected in the end.
