Sodium-Ion Batteries

16Perspectives for Sodium‐Ion Batteries

Effective electrochemical energy storage and conversion technologies, such as rechargeable batteries, have catalyzed the information and communications industry. As one of the most promising next‐generation rechargeable batteries, sodium‐ion batteries (SIBs) have attracted great attention due to the abundant sodium resources and low prices. With the urgent need for large‐scale energy storage, the development of SIBs is opening a new era full of opportunities and challenges, and suitable electrode materials are undoubtedly the key. A successful SIB should have the characteristics of low cost, reliable safety, and long cycle life. The design of active materials is critical to increase the energy density ...
