Battery Industry Weekly Highlights: CATL Partners with Changan Mazda on Skateboard Chassis, DESAY Deploys 4GWh ESS in Mi

Battery

01. DESAY Battery Partners with Germany’s DOS to Deploy 4GWh Energy Storage in the Middle East

DESAY Battery has signed a strategic cooperation agreement with Germany's DOS Primrenergie Sonne GmbH to deploy 4GWh of energy storage stations in the Middle East. The partnership will begin in the Gulf region and aims to develop innovative pathways for energy transition in developing countries. This marks DESAY’s major step toward international ESS (energy storage system) market expansion.

02. CATL and Changan Mazda Team Up on Smart EV Skateboard Platform

CATL has signed an MOU with Changan Mazda to co-develop new energy vehicles based on CATL’s CIIC integrated intelligent chassis. The partnership will leverage CATL’s modular skateboard platform—featuring standardized interfaces and hardware-software decoupling—to accelerate multi-model adaptability and shorten development cycles for complete vehicles.

This marks a deeper collaboration on skateboard chassis technology, a critical foundation for next-generation smart electric vehicles. The move is expected to drive faster commercialization and support China's ongoing EV transition.

Additionally, CATL has recently passed the AS9100 Aerospace Quality Management System Certification, the highest global quality standard in aerospace manufacturing, required by Boeing, Airbus, Lockheed Martin, and other major OEMs.

Materials

01. BTR Releases Full-Spectrum Solid-State Battery Material Solutions

BTR (Beitri) has launched a comprehensive solid-state battery material platform, including:

• BEAN FLEX semi-solid & GUARD full-solid series with high-nickel cathodes

• Silicon-based anodes with specific capacity up to 2300 mAh/g

• Composite solid electrolytes, including polymer–oxide hybrids and sulfide-based systems

• Lithium-carbon composite anode materials

These materials aim to address performance, safety, and scalability in next-gen all-solid-state battery technologies.

02. New 6000t High-Purity Lithium Sulfide Project Announced in Weifang

Weifang’s Ecology and Environment Bureau has disclosed a proposed project for 6,000 tons of high-purity lithium sulfide (used in solid-state batteries) and 26,000 tons of high-performance zinc sulfide. The project, led by Shandong Dayao Special Materials Co., Ltd., is currently under environmental impact assessment and is part of the region’s push into advanced battery material production.

Equipment

01. Yifei Laser Rolls Out First Overseas Automated Energy Storage Container Line

Yifei Laser has successfully delivered its first overseas full-automation assembly line for energy storage containers. Designed for an international client, the production line supports battery systems from 50Ah to 314Ah and has an annual output capacity of over 5GWh.

The line covers the full process flow from cell processing, module/PACK assembly, to final container integration and system-level testing. This marks a significant step in Yifei’s global strategy and reflects growing international demand for scalable ESS manufacturing solutions.
