HyperStrong and CATL Sign 60 GWh Sodium-Ion Battery Agreement to Advance Energy Storage

April 27, Beijing - Beijing HyperStrong Technology Co., Ltd. ("HyperStrong") and Contemporary Amperex Technology Co., Limited ("CATL") signed a strategic cooperation agreement on sodium-ion batteries for energy storage, establishing a three-year partnership totaling 60 GWh, marking a pivotal milestone toward the large-scale deployment of sodium-ion batteries in the energy storage industry.

HyperStrong and CATL have maintained a long-term strategic partnership, and this agreement represents a new phase in expanding their collaboration. The two companies will work closely across technology R&D, product applications, and project implementation, aiming to accelerate the commercialization of sodium-ion batteries for energy storage. This agreement represents the world's largest sodium-ion battery cooperation announced to date.

Sodium-ion batteries offer distinct advantages, including wide operating temperature adaptability, strong high-temperature cycling performance, lower heat generation during operation, reduced mechanical stress from cell expansion, and enhanced safety and stability. In long-duration energy storage applications, sodium-ion batteries can simplify system architecture, reduce auxiliary power consumption, and improve overall efficiency and project economics. They also demonstrate significant potential in facilitating renewable energy integration in remote areas.

The agreement was signed in Ningde, China, with senior executives from both companies present to witness the occasion.

As sodium-ion batteries enter a scaling development phase, both parties will continue to deepen their collaboration, promote high-quality development in the energy storage industry, and provide more resilient and diversified technological solutions to support the global energy transition.
