Abstract
In the quest for sustainable and cost-effective energy storage solutions, sodium-ion batteries (SIBs) have emerged as a promising alternative to lithium-ion batteries, owing to their similar chemical compositions, mechanisms, and compatibility with existing battery technologies. Despite their potential, SIBs face challenges such as lower capacity and structural instability, which hinder their widespread adoption. This paper provides a comprehensive overview of cathode materials used in SIBs, focusing on their electrochemical properties, limitations, and the ongoing research aimed at overcoming these challenges. We delve into the current state of SIB technology, highlighting the critical role of cathode materials in enhancing the performance, durability, and cost-effectiveness of SIBs. Furthermore, we explore future directions for research and development, including novel materials and innovative approaches to improve the capacity and structural stability of SIBs. By addressing these key issues, this paper aims to contribute to the advancement of SIB technology and its application in next-generation energy storage systems.
