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.
