According to information from the official website of 宁德时代 (CATL), CATL and HyperStrong have signed a strategic cooperation agreement on sodium-ion battery energy storage in Ningde, Fujian. The two parties will collaborate on a 60GWh sodium-ion battery order over the next three years, marking the largest sodium-ion energy storage cooperation globally to date.

This partnership signals that sodium-ion batteries are entering a new phase of large-scale commercial deployment. Both companies will deepen cooperation in R&D, product applications, and project implementation, accelerating the adoption of sodium-ion technology in long-duration energy storage scenarios.

CATL stated that it has achieved significant breakthroughs in material systems, manufacturing processes, and system integration, improving energy density, wide-temperature performance, and overall system safety. The technology is also highly compatible with existing lithium battery supply chains, helping to reduce system costs and improve deployment efficiency.

Industry trend insights
With rapidly growing demand for long-duration energy storage, the global energy storage industry is accelerating toward:

• Diversification of technologies (Lithium + Sodium-ion coexistence)
• Rapid deployment of large-scale storage projects
• Cost efficiency and system safety becoming key competitiveness drivers

This is driving continued growth in demand for:

• Battery Energy Storage Systems (BESS/ESS)
• Grid-scale energy management and dispatch systems
• Renewable energy integrated storage solutions
• Smart energy system integration

For energy storage companies, system integrators, and investors, the global market is entering a new expansion cycle with increasing project opportunities.
