340Wh/Kg
NOW AVAILABLE
Less than a year after launching our facility, we are proud to announce that ADVANTELEC has become the first European manufacturer to offer 340 Wh/kg cells! With our new High Energy range, we produce cells that are 15% more energy-dense and significantly lighter. This major breakthrough is just the beginning! More innovations will follow in the coming months.

We recently had the pleasure of welcoming Thomas Gassilloud, Member of Parliament for the Rhône and member of the National Defense and Armed Forces Committee, to our facilities in Vénissieux. This visit was part of his parliamentary work on defense and sovereignty industries, where he advocates for close dialogue between industry and public decision-makers to build sustainable and sovereign reindustrialization.
Our teams presented our high-density lithium cell mega-factory, the first of its kind in France. Commissioned in April 2025, the facility spans 1,300 m², including 650 m² of cleanrooms, and produces cells with energy density up to 350 Wh/kg designed for drones and ground robots. With an annual capacity of 20 MWh, it demonstrates our ambition to relocate battery manufacturing and strengthen industrial sovereignty.
Thomas Gassilloud commended our commitment to innovation, environmental responsibility, and local roots. His discussions with our teams highlighted the importance of a French industry that innovates, recruits, and transforms itself in service of our armed forces and mobility sectors.
Thank you to him for his support and recognition of the work accomplished! We continue our efforts to improve our processes and develop partnerships in France and across Europe. Together, let's move toward a more sustainable, more sovereign, and more humane industry.
Heading toward industrial sovereignty

Official Opening of Our Vénissieux Facility.
On September 25, 2025, we officially opened our new production site in Vénissieux, marking a major milestone in ADVANTELEC's development.
This state-of-the-art facility houses France's first high-density lithium cell mega-factory, spanning 1,300 m² with 650 m² of cleanrooms. The site produces cells with energy density up to 350 Wh/kg for drones and ground robots, with an annual capacity of 20 MWh.
This inauguration represents a significant step forward in our commitment to relocating battery manufacturing to France and strengthening industrial sovereignty. The facility enables us to meet growing demand from defense and mobility sectors while maintaining the highest standards of quality and innovation.
With this new production capacity, ADVANTELEC is well-positioned to support our partners and clients with cutting-edge energy solutions made in France.
