Major Milestone | ProLogium and TDAC Announced US$50 Million Committed Primary Capital Investment
Yesterday, ProLogium and TDAC jointly announced a US$50 million primary capital investment commitment from a consortium of existing shareholders in support of the parties’ announced business combination.
This commitment represents more than financial backing. It reflects the continued confidence of long-term shareholders who have supported ProLogium’s journey, recognizing our technological leadership, execution capabilities, and long-term vision. It also underscores strong market confidence in our strategy to commercialize next-generation lithium ceramic battery and expand our global footprint.
We sincerely thank our existing shareholders for their continued trust and support as we enter this important new chapter.
Key highlights:
Strengthened market confidence: Continued investment from existing shareholders reinforces confidence in ProLogium’s technology, commercialization capabilities, and long-term growth strategy.
Accelerating commercialization: The investment is expected to support the expansion of next-generation lithium ceramic battery mass production, advance construction of ProLogium’s Dunkirk Gigafactory in
France, and accelerate growth across emerging applications, including data centers, aerospace, and robotics.
Every act of support is a vital force driving innovation forward; every new partner who joins makes the path from technological breakthrough to large-scale application of next-generation lithium ceramic batteries all the more solid. This is a milestone achievement worth sharing together, and also the beginning of another journey. ProLogium will continue to engage and collaborate, with a pragmatic and prudent approach, with more investors, industry partners, and global collaborators who share our long-term vision.
Looking ahead, ProLogium will continue to engage with investors, industry partners, and collaborators around the world who share our long-term vision, working together to deliver safer, higher-performance, and scalable energy solutions that accelerate the global adoption of next-generation lithium ceramic batteries.

About ProLogium
Founded in 2006, ProLogium is an energy innovation company dedicated to the development and manufacturing of next-generation lithium ceramic batteries, holding over 1,100 global patents (granted and pending). In 2013, ProLogium commercialized solid-state batteries, primarily for use in smartphones charging cases and since then, ProLogium has delivered in the aggregate more than 2.4 million battery products to its collaboration partners and customers, including cells used in automotive audio systems and approximately 10,000 samples for automotive applications. In 2025, ProLogium introduced superfluidized inorganic next generation lithium ceramic battery, integrating the advantages of solid-state and liquid type batteries and redefining next-generation battery technology with scalable manufacturability and cost competitiveness. In 2026, ProLogium once again received the Edison Awards Gold Award for its superfluidized inorganic next generation lithium ceramic battery technology.
With more than 13 years of manufacturing know-how, ProLogium is among the first companies to successfully commercialize a high-efficiency roll-to-roll coated ceramic separator manufacturing process and its Taoke facility announced that it was the first commercial next-generation lithium ceramic battery gigafactory to publicly display the production line—reflecting that next generation lithium ceramic batteries represent a feasible solution for scalable manufacturing rather than a laboratory project. ProLogium’s first GWh-class gigafactory, Taoke facility, is located in Taoyuan, Taiwan. In 2024, ProLogium established its first overseas R&D center in Paris-Saclay, France, providing customized technical support for the European market. ProLogium’s second battery gigafactory is located in Dunkirk, France, where groundbreaking for its Phase 1 facility took place in February 2026 and the project is proceeding to the detailed design and construction stage. The Phase 1 facility will have a designed production capacity of 4.0 GWh when complete, which ProLogium expects to achieve gradually by 2030. The Dunkirk facility site will have a maximum designed production capacity of 44.0 GWh and is intended to work closely with ProLogium’s Paris-Saclay R&D center.
