ProLogium Opens First Ceramic Battery Giga Factory

ProLogium Technology, a global leader in solid-state battery innovation, has inaugurated its Taoke factory in Taiwan. Most importantly, the plant marks the company’s significant milestone in the battery industry.

Chief Secretary of Ministry of Economic Affairs Chih-Ching Yang, the Director of the French Office in Taipei Franck Paris, and Taoyuan City Mayor Shan-zheng Zhang led the company’s guests. French delegation from Dunkirk also celebrated the opening of the world’s pioneering giga-scale solid-state lithium ceramic battery facility. Key strategic partners, including Mercedes-Benz, POSCO, FEV, Arkema, and banks from both Taiwan and France, were also present to witness this historic moment.

Moreover, the unveiling of 106Ah solid-state battery manufactured with high-silicon anode at the facility was among the event’s highlights. The battery is suitable for electric vehicles. Hence, ProLogium not only showcased its proprietary manufacturing technology for solid-state batteries but also highlighted the commercial viability.

Vincent Yang, the founder and CEO of ProLogium said the breakthrough next-generation solid-state battery is a product of 17 years of dedicated effort. Moreover, Yang said, “Our journey has been a testament to overcoming existing technological barriers and innovating new structures. (Thus), leading to a fundamental transformation in cell structure and process design. We have overcome the bottlenecks in traditional batteries and this breakthrough combines performance, cost efficiency, and resource circulation, manifesting a new universe for the battery industry.”

ProLogium’s Taoke plant not only serves as the best demonstration for scaled production but is also the design prototype for its future global expansion, especially the design of the Dunkirk gigafactory

Furthermore, Yang said ProLogium will globally promote the achievements of the Taoke factory. Particularly, propelling the industrialization of solid-state batteries and supporting global automakers and governments in their quest for net-zero emissions.

Breaking  Technological Barriers

The Taoke factory, with a planned capacity of 2GWh based on market demand, will likely supply batteries for up to 26,000 electric vehicles1. Since late 2023, the facility has commenced production and plans to distribute high-capacity solid-state batteries for electric vehicles worldwide. This facility is a demonstration factory for future global expansion, particularly in Dunkirk, France. Moreover, it also is a significant contributor to the local economy in Taoyuan, potentially creating 1,200 jobs.

The Taoke factory will continue to advance its technology, achieving the “P-C-R Next-Generation Solid-State Battery” solution.

This new battery structure not only ensures a high level of safety but also paves the way for continuous improvements in lithium battery performance. Particularly, future advancements in materials will further enhance driving range, maximize resource utilization, and reduce costs. Thus, striking an optimal balance between “Performance,” “Cost,” and “Resource Circulation.”

Breaking the industry’s previous perception of solid-state battery production is highly challenging and costly. ProLogium has continued expanding production capacity while consistently upgrading through process iterations for commercially competitive solid-state batteries.

The Taoke factory’s output efficiency2 is 2.6 times greater than its original facility, with doubled assembly speed and innovative manufacturing technologies. That is, solid-state electrolytes made by continuous wet coating without the process of liquid electrolyte injection, soaking, and degassing. This improves production efficiency and quality and reduces manufacturing costs.

Moreover, ProLogium has successfully overcome the challenges that solid-state batteries have faced in terms of mass production and economics. Thus, reaching a scale where manufacturing costs can be lowered to the same level as mainstream batteries.

In addition, among ProLogium’s patented technologies, there are hundreds of techniques designed with the goal of improving product yield. Thus, covering cell structure and process design. In terms of cell structure, ProLogium’s original Logithium™ structure and corresponding process have successfully improved the potential yield issue of solid-state batteries. Moreover, it greatly enhanced the accuracy of alignment and cathode and anode attaching during the manufacturing process. Currently, the company has achieved a yield target of 99.9% for single-layer cells on the trial production line, and the Taoke factory continues to optimize yield based on this goal.

Taiwan-France Cooperation

France has included ProLogium in the “France 2030” plan and the preparation for the Dunkirk factory is progressing well. Moreover, the smooth progress of the first phase public concertation for the construction of the gigafactory in Dunkirk, France. Furthermore, the official inclusion of ProLogium in the “France 2030” plan, reaffirm that ProLogium aligns with the French government’s vision of developing energy-efficient transportation. Franck Paris, Director of the French Office in Taipei, expectantly stated, “ProLogium has put Taiwan on France’s map and put France on Taiwan’s map.”

Franck Paris, Director of the French Office in Taipei stated. “I want to thank ProLogium for choosing France to expand their production line. (I) extend my gratitude to everyone who played a role in making this project happen. The French government will provide full support to ProLogium. Today’s grand opening is significant on the business. In addition, it also represents the potential of Taiwan-France cooperation and our role as leaders in the global green economy.
