World's Largest Sodium-Ion Storage Deal: 60 GWh CATL-HyperStrong Agreement

CATL and HyperStrong Sign Historic 60 GWh Sodium-Ion Battery Storage Agreement

On May 4, 2026, CATL, sourceL, and HyperStrong signed the world's largest sodium-ion energy storage strategic cooperation agreement, covering a total supply of 60 GWh over three years. HyperStrong becomes CATL's first strategic partner in the sodium-ion energy storage sector, focusing on joint R&D, product applications, and large-scale project deployment.

CATL has successfully resolved critical mass production challenges, including foaming and moisture control, enabling reliable large-scale delivery of sodium-ion batteries. This breakthrough marks a pivotal milestone for the global sodium-ion battery industry, particularly for long-duration energy storage applications.

Implications for B2B Buyers and Energy Storage Markets

This agreement signals a major shift in the energy storage supply chain. For B2B buyers, sodium-ion technology offers a cost-effective and safer alternative to lithium-ion, with abundant raw materials reducing supply risk. The 60 GWh commitment over three years provides price stability and volume assurance for large-scale projects.

• Reduced dependency on lithium and cobalt, lowering geopolitical and pricing volatility.
• Enhanced safety profile for utility-scale and industrial storage systems.
• Accelerated deployment of long-duration storage, supporting renewable integration and grid stability.

According to the official announcement, this cooperation will drive global sodium-ion battery expansion, with HyperStrong leveraging its system integration expertise to bring these batteries to market faster. Industry analysts view this as a turning point for sodium-ion commercial viability.
