Solithor and Sonaca to Develop Battery Systems for UAM

In the partnership, Solithor will be responsible for cell research, development, testing characterisation, format design and production of 10Ah-40Ah, whilst Sonaca will develop the battery packaging, and certify the battery system By Joe Macey / 28 Feb 2023

Belgian Lithium battery technology company Solithor and aerospace company Sonaca have signed a Memorandum of Understanding (MoU) to develop safe, high-density rechargeable solid-state Lithium battery systems for Regional Aircraft and Urban Air Mobility (UAM).

The partnership is also expected to expand to satellite systems as well as defense systems. The alliance will divide key activities in the research, development, production and integration of cells and battery systems designed for powering aircraft.

Solithor will be responsible for cell research, development, testing characterization, format design and production of 10Ah-40Ah cell as it forges ahead. Sonaca will develop the battery packaging including all related management systems. It will also certify the battery system.

The cells will be produced and manufactured by Solithor in Sint-Truiden, Flanders, Belgium and the integration of the aircraft battery systems will take place at Sonaca’s plant in Charleroi, Wallonia, Belgium.

Sonaca has set itself the ambitious goal of proactively contributing to the development of a low-carbon aircraft by 2035 and achieving carbon neutrality by 2050. That is why in order to achieve such ambitious goals the demand is for the industry to produce low noise and energy efficiencies in the powering of aircraft. Its believed this would allow the industry to make more effective use of smaller regional airports and go some way to address their under-utilization across the world, especially in the USA and Europe.

Solithor and Sonaca believe that their complementary capabilities will provide the greatest advancements in solid-state Lithium battery systems technologies for all regional aircraft and Urban Air Mobility applications.
