CATL wins the world's largest order for sodium ion batteries

1、 Heavy signing: 3-year 60GWh, unlocking the world's largest sodium electricity order

The strategic cooperation between CATL and Haibosichuang this time is not only an important measure for both sides to deepen their layout in the energy storage field, but also sets a record for the scale of global sodium ion battery orders. According to the agreement, both parties will deeply collaborate in technology research and development, product application, and project implementation. In the next three years, CATL will supply 60GWh sodium ion batteries to Haibosichuang, covering all energy storage scenarios. This is currently the largest sodium ion battery cooperation project in the world.

As the first strategic partner of Ningde Times in the field of energy storage system integration, Haibo Sichuang has a deep accumulation in the field of energy storage system integration. This cooperation will achieve complementary advantages - Ningde Times provides high-performance sodium battery products and technical support, while Haibo Sichuang is responsible for the scenario based application and project implementation of the products, promoting the rapid entry of sodium ion batteries into the energy storage market. At the signing ceremony, the core management of both parties attended and witnessed, demonstrating the high importance attached to cooperation and indicating that the industrialization process of sodium electricity will accelerate comprehensively.

2、 Order confidence: technological breakthroughs and breakthroughs, building a solid foundation for large-scale delivery

The ability to win the world's largest sodium battery order is due to CATL's continuous technological breakthroughs and full chain breakthroughs in the field of sodium ion batteries. On the Super Technology Day on April 21st, CATL announced that it has overcome four major industry challenges in the mass production of sodium ion batteries, including extreme water control, hard carbon gas production, aluminum foil bonding bottleneck, and large-scale production of self generated negative electrodes. It has solved hundreds of engineering problems one by one and officially achieved large-scale delivery capabilities.

At the technical level, CATL has significantly improved the energy density of sodium ion batteries through morphology control and surface modification; With the help of core technologies such as Emi level aperture adjustment, the production difficulties of foaming and moisture control in hard carbon production lines have been systematically solved, ensuring the consistency of large-scale products. The sodium new battery developed by it not only has significant cost advantages, with a cost gap of 30% to 40% compared to lithium iron phosphate batteries, but also has excellent wide temperature range adaptability and safety stability. In long-term energy storage scenarios, it can simplify system architecture, improve power plant operation efficiency, and perfectly meet the core needs of the energy storage field.
