Abstract

This study focuses on the structural stability of Prussian blue analogue (PBA) cathode materials in sodium-ion batteries and its impact on sodium storage performance. This research has significant theoretical and practical value because PBA materials exhibit defects such as structural vacancies and incomplete coordination between crystal water and metals in practical applications. These factors directly affect the crystal stability of the material, thus determining the capacity retention, performance, and cycle life of sodium-ion batteries. Structural stability is not only a key factor for the industrialization of materials but also a scientific problem in sodium-ion battery systems that remains unresolved. Most existing research focuses on the electrochemical performance testing or synthesis methods of PBA materials, but few studies systematically review the impact of structural stability on the sodium storage performance of sodium-ion batteries. This study employs a literature review and interdisciplinary approach, systematically organizing the relationships between different structural defect types, synthesis strategies, and electrochemical performance to analyze the influence of structural stability on sodium storage performance. This study will provide a systematic review of the impact of structural stability on sodium storage performance from the perspectives of crystal structure and electrochemical mechanisms, using literature analysis, comparative studies, and theoretical induction. This study aims to deepen our understanding of the structure-performance mechanism of PBA materials; promote the theoretical development of material structure design; and provide reference results for the optimization of cathode materials for sodium-ion batteries.
