This review article provides an in-depth analysis of the recent progress and challenges in sodium-ion batteries (SIBs), focusing on electrode materials, electrolytes, conductive agents, binders, and separators. The authors highlight the advantages of SIBs over lithium-ion batteries (LIBs), such as abundant sodium resources and lower costs, while acknowledging the need for improvements in energy density, fast-charging capability, and cyclic stability. The article is structured into several sections, each addressing specific aspects of SIBs:
1. **Introduction**: Discusses the importance of SIBs as a renewable energy storage solution, emphasizing their potential due to the abundance of sodium resources and the fast diffusion of Na+ ions. It also outlines the limitations of LIBs, such as lithium resource scarcity and high costs.
2. **Cathode Materials**: Reviews the design strategies, synthesis methods, active sites, surrounding environments, and reaction mechanisms of cathode materials. Key types include layered transition metal oxides, polyanionic compounds, Prussian blue analogues (PBAs), and organic compounds. Detailed examples and case studies are provided to illustrate the advancements in these materials.
3. **Electrolytes, Conductive Agents, Binders, and Separators**: Explores the influence of these components on the electrochemical performance of SIBs, including their role in enhancing conductivity, stability, and overall battery performance.
4. **Technical Challenges and Future Research Directions**: Identifies the current challenges in SIBs and proposes potential solutions to overcome them, emphasizing the need for further research in materials science and engineering.
The review aims to provide a comprehensive overview of the latest advancements and future directions in SIBs, highlighting the potential for practical applications in large-scale energy storage systems.This review article provides an in-depth analysis of the recent progress and challenges in sodium-ion batteries (SIBs), focusing on electrode materials, electrolytes, conductive agents, binders, and separators.
