Taiwanese solid-state battery maker Prologium inaugurated its first solid-state lithium ceramic battery gigafactory in Taoyuan Science Park (Taoke), Taiwan. It claimed this as a world first.
The inauguration this week included the unveiling of a 106Ah solid-state battery manufactured with high-silicon anode at the facility. Prologium said its manufacturing technology demonstrates the commercial viability of the next-generation battery structure.
The factory has a planned capacity of 2GWh. It began production in 2023 and acts as a demonstration factory for future global expansion, particularly in Dunkirk, France, the company said.
Solid-state electrolytes are made by continuous wet coating without the process of liquid electrolyte injection, soaking and degassing, it said. This improves production efficiency and quality, and reduces manufacturing costs. It said it is reaching a scale where solid-state battery manufacturing costs can be lowered to the same level as mainstream batteries.
France has included Prologium in the ‘France 2030’ industrial plan, along with its €5.2 billion ($5.7 billion) 48GWh Dunkirk gigafactory. Franck Paris, director of the French Office in Taipei, said: “Prologium has put Taiwan on France’s map and put France on Taiwan’s map.”
Prologium’s first gigafactory production line in Taiwan is due to begin supplying automakers in 2024.
Vincent Yang, the founder and CEO of Prologium, said the company had achieved 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.”
