CATL Secures 60GWh Sodium-Ion Battery Order in Landmark Energy Storage Deal

[Supply Chain] CATL and HyperStrong have signed a three-year agreement for 60GWh of sodium-ion batteries for energy storage—the largest sodium-ion battery collaboration globally to date.

Core Development: 60GWh Order Marks the Industrial Tipping Point for Sodium-Ion Batteries

On April 27, CATL and HyperStrong signed a strategic cooperation agreement in Ningde, Fujian Province, making HyperStrong CATL’s first strategic partner for sodium-ion energy storage solutions. The two parties will closely collaborate on technology R&D, product application, and project implementation.

Key Metrics: 60GWh Delivery Over 3 Years, Compatible with Existing Lithium-Ion Production Lines

Through proprietary techniques such as angstrom-level pore-size tuning and surface molecular water-locking, CATL has overcome challenges related to bubbling and moisture control in hard carbon anode production, enabling high-consistency mass manufacturing. Its sodium-ion batteries adopt a platform design identical in dimensions to lithium-ion cells, significantly reducing integration costs and accelerating deployment timelines.

Strategic Rationale: Sodium-Ion Batteries Offer Enhanced Safety and Cost Efficiency

Sodium-ion batteries exhibit superior performance across wide temperature ranges, generate less heat, and impose lower expansion stress. In long-duration energy storage applications, these attributes simplify system architecture, reduce auxiliary energy consumption, and enhance overall power station efficiency.
