FAQ
What You Should Know About Celtrix
Celtrix provides end-to-end support: from first concept and prototype design to regulatory approval and certified pilot production.
1. What makes Celtrix different from other battery manufacturers?
Celtrix focuses on special-purpose batteries where mass-produced gigafactory cells cannot meet important requirements. We leverage decades of Fraunhofer research, prototyping and manufacturing expertise to deliver cells and systems adapted to demanding applications such as MedTech and Drones. Our proprietary flexible medium-scale manufacturing can meet demands starting from only 6,000 cells per year.
2. What types of battery solutions does Celtrix provide?
Depending on customer needs, Celtrix supplies:
- Bare cells (special formats and chemistries)
- Battery packs
- Complete systems with integrated Battery Management Systems (BMS) and charging solutions
Our flexibility allows us to support projects starting from 6,000 cells per year.
3. Why is European manufacturing important?
Europe depends heavily on battery imports from Asia, even for sensitive applications. Celtrix provides a secure, regional supply chain with production based in Northern Germany, ensuring shorter lead times, greater resilience, and strategic autonomy for European industries.
4. What stage is Celtrix at today?
Celtrix is a Fraunhofer spin-off, currently transitioning European-developed battery technologies into industrial production. We have prototypes in testing with leading MedTech companies, are building partnerships in aerospace and defense, and plan to begin serial production in 2026. Investors and customers can engage with us now to shape the first wave of projects.
