The two parties announced a three-year partnership covering the supply of a total of 60GWh of sodium-ion batteries, marking a significant step in pushing sodium-ion battery technology to the industrial scale.
HyperStrong, as CATL’s first strategic partner in sodium ion energy storage, will work closely with CATL in research and development of technology, product application, and project execution.
This collaboration reflects CATL’s success in innovating across the value chain for high-volume sodium-ion battery production, enabling the company to deliver products in large quantities.
Furthermore, this represents the largest sodium-ion battery supply agreement in the world to date and will usher in a new era of significant expansion for the global sodium-ion battery industry.
CATL has significantly improved the energy density of sodium-ion batteries through morphological control and surface modification.
In manufacturing, the company systematically solved key process challenges such as foaming in hard carbon production lines and moisture control, utiliSing core technologies like angstrom-scale pore size control, surface water molecule locking, and adaptive dynamic shaping to ensure consistent product quality across large-scale production lines.
Sodium-ion batteries exhibit excellent adaptability over a wide temperature range, outstanding high-temperature service life, low operating heat, and lower cell expansion stress, resulting in superior safety and stability.
In long-term energy storage applications, these batteries simplify system integration, minimise excess energy loss, and comprehensively improve the efficiency and economic return of power plants.
Furthermore, CATL’s sodium-ion energy storage batteries are designed on a platform with the same form factor as lithium-ion batteries, enabling seamless integration into existing industrial chains.
This significantly reduces deployment costs and shortens the time from product preparation to installation in power plants.
This collaboration on 60GWh sodium-ion batteries represents a significant achievement for both parties.
CATL and HyperStrong will continue to strengthen their cooperation as sodium-ion technology enters its large-scale development phase, fostering high-quality growth in the energy storage industry and providing a more resilient and diverse technological support for the global energy transition.
