Current Research Directions of Sodium-Ion Battery Materials

The requirement for batteries has been steadily rising in recent years due to the advancement of electric vehicles and the growth of the energy storage industry. Sodium-ion batteries have attracted attention due to their inexpensive cost, wide distribution, and resemblance to lithium-ion batteries. The cathode material, anode material, and electrolyte system—the three main material technologies of sodium-ion batteries—are reviewed in this study along with a brief overview of the problems and developments in these areas of research.
