摘要:

Sb基材料因具有理论容量高、储量丰富、来源广泛、环境友好和安全性高等优势已成为颇具前景的钾离子电池负极材料。但Sb基材料普遍面临结构稳定性较差、动力学迟缓、导电性差等棘手问题,在进行钾离子脱嵌时,材料结构变化大,粉化严重,造成容量衰减过快,仅能获得较差的循环稳定性。此外,固体电解质界面膜(SEI膜)的稳定性也极大地影响着Sb基材料的循环性能。这些问题严重阻碍了Sb基材料发展的脚步。本文归纳了各类Sb基材料的研究进展,重点介绍了通过调控材料结构以及调节电解液体系对电化学性能的影响,对高性能钾离子电池Sb基负极材料的设计做出了展望。

Abstract:

Sb-based materials have become a promising anode for potassium ion batteries (PIBs) due to its advantages of high theoretical specific capacity, abundant reserves, wide sources, environmental friendliness and high safety. However, Sb-based materials generally suffer from many problems such as poor structural stability, sluggish dynamics and indisposed electrical conductivity. In the process of K+ de-intercalation, the structure is prone to obvious changes and even material pulverization, resulting in rapid capacity decay and poor cycle stability. Furthermore, the stability of solid electrolyte interface film (SEI) also greatly affects the cycling performances of Sb-based materials. These problems seriously hinder the development of Sb-based materials. Herein, the research progress of various Sb-based materials is summarized, the influence of adjusting structure and electrolyte system on electrochemical performance is emphasized, and the design of Sb-based anode materials for high-performance PIBs is prospected.
