Chapter 3: Intercalation-based Layered Materials for Rechargeable Sodium-ion Batteries

Rechargeable sodium-ion batteries (SIBs) are becoming more popular day-by-day as an alternative to lithium-ion batteries (LIBs) due to their low cost and on par high specific energy. However, a lack of suitable electrode materials is a major problem with its commercialization. Layered materials are the most promising electrodes and are extensively used for SIBs. In this chapter, a brief history of SIB development and its working principle are discussed. In addition, the electrochemical reactions, mechanism of structure evolution, stability and challenges of layered electrode materials are also discussed. The full cell developments of SIBs based on layered electrode materials are briefly mentioned.
