Developments in Sodium-Ion Based Cathode Materials for Energy Storage Applications

The rising need for energy is a major worldwide issue fueled by several causes. The goal of meeting this increasing demand while simultaneously taking care of the environmental problems and guaranteeing energy security is challenging. Various renewable, non-renewable, and alternative energy sources have been used to fulfill the rising needs. However, a suitable energy storage system is also essential since it addresses the intermittent character of many renewable energy sources and makes it possible for a more reliable and adaptable energy supply in modern energy systems. The growing need for energy storage solutions across various applications, such as electric vehicles (EVs), consumer electronics, renewable energy integration, and grid-scale energy storage, is the driving force behind the thriving and quickly developing lithium-ion battery (LIB) research field. The performance, security, economic viability, and environmental sustainability of LIBs are the main research areas. Sodium-ion batteries (SIBs) are a desirable replacement for traditional LIBs since sodium is plentiful and could reduce manufacturing expenses. In this chapter, we’ve addressed the fundamentals of SIBs, synthesis, and advancements in the electrochemical performance of cathode materials of SIBs. Additionally, a summary of sodium-ion battery commercialization to date has been provided. The cathode materials that have been synthesized up to this point have been thoroughly compared, i.e. recent research progress has been provided in brief.
