Metal–organic compounds as promising anode materials for potassium ion batteries: A mini review
Potassium-ion batteries (PIBs) represent one of the most promising alternatives to lithium-ion batteries (LIBs), owing to their exceptional attributes such as high voltages, potent power capabilities, and cost-effectiveness. Nonetheless, challenges arise from the sluggish kinetics and significant volume expansion observed during the insertion/extraction of large-radii potassium ions, leading to subpar rate performance and considerable capacity degradation in potassium-ion batteries. Consequently, it becomes imperative to explore advanced anode materials exhibiting high electrochemical activity and robust structural stability. In this regard, the present review focuses on recent progress in metal-organic compounds (MOCs) as anode materials for potassium-ion batteries, systematically discussing their outstanding merits from the perspective of metal speciation. Additionally, the principal mechanism of K ion storage within relevant MOCs is presented. Furthermore, a comprehensive summary of existing drawbacks that hinder the broader application of MOCs-based materials is provided, along with proposed guidelines and strategies for addressing the inferior performance characteristics. This review serves to illuminate the development of MOCs-based anode materials for potassium-ion batteries and offers a valuable reference for future research endeavors.
