Sodium-ion batteries show great potential as an alternative energy storage system, but safety concerns remain a major hurdle to their mass adoption. This paper analyzes the key factors and mechanisms leading to safety issues, including thermal runaway, sodium dendrite, internal short circuits, and gas release. Several promising solutions are proposed, such as high-safety electrode materials in the cathode and anode, high-safety electrolytes, and external battery management systems. Here in also we emphasize the importance of selecting appropriate analysis methods and developing reliable failure models while suggesting advanced machine learning tools for analysis. With a comprehensive approach, this study offers valuable recommendations to optimize materials and solutions for improving the safety of sodium-ion batteries.

The development of large scale energy storage systems (ESSs) aimed at application with renewable electricity sources and in smart grids is expected to address energy shortage and environmental issues. Sodium ion batteries (SIBs) exhibit remarkable potential for satisfying the raw material supply and economic requirements of large scale ESSs because of the high richness and accessibility of sodium reserves. High stability of electrodes during cycling means long service life for energy storage, which is important for large scale ESSs to reduce the cost s generated by exchange or maintenance processes. Using low cost and abundant elements in cathodes with long cycling stability is preferable for lowering expenses on cathodes because it is vital for large scale ESSs to cut costs resulting from manufacture, exchange, and maintenance operations.
Organic electroactive compounds hold great potential to act as cathode materials for SIBs because of their environmental friendliness, sustainabilit
