As CATL's first strategic partner for energy storage sodium-ion batteries, HyperStrong will collaborate closely with the battery giant on R&D, product application, and project execution.
The collaboration underscores CATL's success in cracking the full chain of mass-production challenges, confirming its ability to deliver at scale. It stands as the largest single order for sodium-ion batteries globally to date, kicking off a new phase of explosive growth for the industry.
CATL has significantly boosted energy density through morphology control and surface modification. On the manufacturing front, the company leveraged core technologies—such as angstrom-level pore adjustment, surface molecular water locking, and adaptive dynamic formation—to systematically resolve production hurdles like bubbling in hard carbon lines and moisture control. These advances ensure consistency across high-volume production runs.
Sodium battery materials offer superior temperature adaptability and excel in high-temperature cycle life. They generate less heat and experience lower cell expansion stress during operation, delivering enhanced safety and stability. For long-duration energy storage applications, this allows for a simplified system architecture that cuts auxiliary energy losses—ultimately boosting power station efficiency and overall economics.
Furthermore, CATL's energy storage sodium-ion batteries share a platform design with their lithium-ion counterparts, ensuring high compatibility with existing supply chains. This compatibility lowers integration costs and significantly shortens the timeline from production to power station deployment.
The 60GWh partnership represents a major breakthrough for both companies. As sodium-ion technology enters its scale-up phase, the two plan to deepen their collaboration to drive high-quality growth in the storage sector—providing a more resilient and diversified technical foundation for the global energy transition.
