BASF and Weilan in the field of solid-state batteries

Significant progress made in deep cooperation

BASF Shanshan Battery Materials Co., Ltd. (hereinafter referred to as BASF Shanshan), a subsidiary of BASF Battery Materials, has achieved significant breakthroughs in next-generation battery technology.

Through deep collaboration with Beijing Weilan New Energy Technology Co., Ltd. (hereinafter referred to as Weilan New Energy), BASF has successfully delivered the first batch of mass-produced cathode materials for semi-solid-state batteries, taking a solid step toward the industrialization of solid-state batteries.

New Energy

With the rapid development of the new energy industry, the market has raised higher requirements for the energy density and safety of batteries. Solid-state batteries, including semi-solid-state batteries, are regarded as an important development direction for next-generation battery technology and have received widespread attention.

Weilan New Energy is a leader in the solid-state battery field.

Pioneer with over 40 years of solid-state battery experience

With experience in industry research, the products are mainly applied in areas such as new energy vehicles, energy storage, low-altitude flight, and power tools. BASF Shanshan has over 20 years of experience in the development and production of battery cathode materials, with the ability to solve key challenges in solid-state battery materials.

Completed in just one year

From concept to mass production======

Starting from August 2024, through close collaboration and a shared pursuit of high-tech innovation, both parties completed the entire process from concept to mass production within just one year.

The BASF Shanshan R&D team has designed ultra-high nickel (nickel-cobalt-manganese) cathode materials with a unique composite coating layer to address the interface issues between cathode materials and solid-state electrolytes. This innovative technology not only...Increased energy density with higher capacity and lower impedance.Furthermore, by effectively suppressing the interfacial side reactions between the cathode active material and the electrolyte,Significantly improved the cycling performance and calendar life of the product.Therefore, this collaboration is indeed a milestone for the next generation of advanced batteries.

As the lead in technology research and development for both parties in this collaboration,Chief Technology Officer of BASF Shanshan, Xia Xin"The successful implementation of this cooperation is attributed not only to the advanced technical capabilities of both parties but also to the sincere collaboration between the technical teams."

Li Wenjun, Dean of Weilan New Energy Engineering Institute"We are very proud to be able to contribute together to the future of the battery industry!"

General Manager of Weilan New Energy

We are impressed by BASF's excellent technology and rapid response. As a global leader in solid-state battery manufacturing, we will use BASF's cathode materials in Welion's new generation of semi-solid-state batteries and look forward to more collaborations both domestically and internationally.
