Understanding the Design of Cathode Materials for Na-Ion Batteries

Given the increasing demand for sustainable energy sources, sodium-ion batteries (SIBs) emerge as a practical choice for large-scale energy storage grid applications, especially when compared to the currently dominant lithium-ion batteries (LIBs). This preference is primarily due to the cost-effectiveness of sodium precursors. However, it’s important to note that the commercialization of SIBs has faced obstacles, mainly related to the efficiency of current electrode materials, particularly cathodes.

Considering the potential future applications of SIBs, this concise review aims to highlight the inherent challenges associated with various extensively researched cathode materials, including layered transition metal oxides, polyanionic compounds, and Prussian blue analogues. Furthermore, we delve into the commercial viability of these materials, taking relevant parameters into account.

The insights provided within this review can be valuable in guiding the design of more efficient cathode materials for advanced sodium-ion batteries (SIBs).
