About Celtrix
Celtrix GmbH develops and produces custom battery cells and battery systems for applications that standard cells from high-volume factories do not cover. The portfolio includes bare cells in special formats and special chemistries, battery packs, and complete systems with integrated Battery Management Systems (BMS) and charging solutions. On a proprietary, highly flexible manufacturing platform, the company delivers flexible small to medium series starting from 6,000 cells per year. The end-to-end support ranges from the initial concept through prototype design and regulatory approval to certified pilot production; every cell undergoes rigorous cell testing. Target industries are MedTech, drones, maritime autonomous vehicles, aerospace, defense, and microchips with wafer-integrated microbatteries. Production is scheduled to launch in 2026 in Northern Germany, embedded in the Northern German battery cluster with regional, secure supply chains.
