Bosa Energy, based in Hubei, has announced the launch of its new 175 Ah sodium-ion battery cells, marking another step forward in the evolution of alternative battery technologies. While not among the largest battery manufacturers globally, the development highlights the growing momentum of sodium-ion solutions as a complement to lithium-ion batteries in energy storage applications.
The company has four factories in China, which together cover about 500,000 square meters. This large manufacturing footprint helps the company grow its production and bring new technologies to market.
The fact that the new sodium-ion cell works with existing battery systems is one of its most important features. The company says that the cell “is the same size as the 314 Ah cell,” which means it can easily fit into existing infrastructure without needing any design changes. This compatibility is a big plus for manufacturers and developers who want to switch to or add to their battery technologies.
Highlighting the practical benefits, the company further stated that “existing equipment and products can be directly replaced, significantly saving R&D time and modification costs, enabling efficient deployment and upgrades.”
This approach is expected to reduce transition barriers and accelerate adoption across energy storage projects.
The 175 Ah sodium-ion cell has a mass energy density of 110 Wh/kg and a volumetric energy density of 206 Wh/L. The cell is 174.2 mm x 71.6 mm x 204.4 mm and weighs 4.75 kg, which makes it good for standard uses.
The launch underscores the increasing role of sodium-ion batteries in the global energy storage landscape, particularly as industries seek cost-effective and sustainable alternatives to lithium-based technologies.
