Sodium-air Battery Market Size

Sodium-air Battery Market size was over USD 2.12 billion in 2024 and is projected to cross USD 5.05 billion by the end of 2037, growing at more than 6.9% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of sodium-air battery is estimated at USD 2.24 billion.

This growth in the market revenue is poised to be dominated by growing demand for electric vehicles. For instance, approximately 9 million electric cars were purchased in 2022 and this year it is set to expand at about 34% which equates to close to 13 billion electric vehicles. Hence, the demand for sodium-air batteries is estimated to rise. Moreover, the government is offering subsidies for the purchase of electric vehicles which has driven more attention from common people.

Additionally, the use of porous carbon in the cathode of sodium-air batteries is also set to grow owing to it being lightweight. However, besides this porous carbon has an exceptionally specific surface area and pore structure and is also composition-designable. Furthermore, porous carbon has outstanding mechanical and electrical qualities owing to the high electrical conductivity of carbon materials and their distinctive microstructure. Therefore, with the growth in manufacturing of lightweight porous carbon the market demand might grow but there is still more research to be done in this field. Hence, the rise in R&D activities in the utilization of lightweight porous carbon in the cathode of sodium-air battery is expected to expand market growth in the coming years.
