The article reviews recent progress in electrode materials for sodium-ion batteries (NIBs), focusing on both positive and negative electrode materials. It highlights the advantages of NIBs over lithium-ion batteries (LIBs) due to the abundance and accessibility of sodium. The review covers various cathode materials, including layered transition metal oxides (TMOs), polyanionic compounds, and other phosphate compounds. Layered TMOs, such as NaFePO4 and Na3V2(PO4)3, are discussed for their high theoretical capacities and structural stability. Polyanionic compounds, like NASICON-type materials, are explored for their open-framework structures and fast Na ion conduction. The article also examines fluorophosphates, which offer high-voltage capabilities and stable cycle properties. Additionally, it discusses the challenges and perspectives in developing NIBs, emphasizing the need for further improvements in energy, power density, and electrochemical stability.The article reviews recent progress in electrode materials for sodium-ion batteries (NIBs), focusing on both positive and negative electrode materials.
