2026-04-30 | Calvin

On April 27, CATL and Haibosi Chuang signed a strategic cooperation agreement on sodium-ion energy storage batteries in Ningde, Fujian. The two parties announced a 3-year, 60 GWh sodium-ion battery order collaboration, marking a turning point for the industrialization of sodium-ion batteries.

As CATL's first strategic partner in sodium-ion energy storage, Haibosi Chuang will work closely with CATL in technology research and development, product applications, and project implementation. On the same day, Li Yue, Vice President of CATL’s China Zero-Carbon Energy Division, and Zhao Qing, Vice President of Haibosi Chuang, signed the agreement on behalf of their respective companies. The signing ceremony was witnessed by Zheng Yelai, Co-President of CATL’s Market System and General Manager of the Zero-Carbon Energy Division; Xiao Lina, Executive President of CATL’s Zero-Carbon Energy Division; and Shu Peng, Co-founder and Chief Operating Officer of Haibosi Chuang.

This collaboration signifies that CATL has overcome the challenges of the full-chain mass production of sodium-ion batteries and possesses large-scale delivery capability. It represents the largest sodium-ion battery order in the world to date and initiates a new phase of global large-scale development in the sodium-ion battery industry.

CATL has significantly improved the energy density of sodium-ion batteries through morphology control and surface modification. In terms of manufacturing processes, the company has systematically addressed production challenges such as hard carbon foaming and moisture control using core technologies including angstrom-level pore adjustment, surface molecular water-locking, and adaptive dynamic formation, ensuring product consistency at scale.

Sodium-ion batteries offer wide-temperature material adaptability, outstanding high-temperature cycling life, lower heat generation during operation, reduced cell expansion stress, and superior safety and stability. In mainstream long-duration energy storage applications, system integration can effectively simplify the overall energy storage system architecture, reduce auxiliary energy losses, and comprehensively enhance power station operational efficiency and overall economic performance.

Additionally, CATL's sodium-ion energy storage batteries adopt a platform design compatible with the dimensions of lithium-ion batteries. This high compatibility with the existing industry chain effectively reduces adaptation costs and significantly shortens the timeline from product development to power station deployment.

The 60 GWh sodium-ion battery collaboration marks a major milestone for both parties. As sodium-ion batteries enter a phase of large-scale development, the two companies will continue to deepen their cooperation, promoting high-quality development of the energy storage industry and providing more resilient and diversified technological support for global energy transition.
