As part of the energy transition, Lithium batteries are one of the most relevant answers, currently available, to decarbonize air traffic Nevertheless, securing, certifying and producing these technologies for aeronautics and defense remains a real R&D and certification challenge.

In the face of this situation, Limatech is positioned as a designer and producer of secured and certified lithium battery packs for aeronautics and defense.

For this purpose, Limatech has integrated the following expertises :

  • – Mechatronic design (mechanics, electronics and software)
  • Qualification of accumulators and ETSO battery packs
  • Assembly, welding on accumulators and quality controls
  • Compliance with aerospace standards and approvals: EN 9100 & PART 21 (ApDOA & POA)

The disruptive technologies from Limatech, which emerged from the CEA in 2015, have received prestigious awards from MIT (EmTech 2017 / Top 10 most innovative start-ups) and Airbus (Aeronautical Innovation Prize).

In order to ensure industrial excellence and faster supplier qualifications, Limatech passed the EN9100 certification (aerospace quality management system) Part 21 design and production approvals from EASA are in the process of being obtained.

Limatech’s ambition is to become the world leader in the design and manufacture of lithium batteries for aeronautics and defense, replacing the current heavy and polluting lead and nickel-cadmium technologies with smart, safe and more eco-friendly technologies.
