We design and build disruptive aerospace battery systems.

First ideas and prototyping started in 2021 by Ex-Lilium engineers passionate about batteries and aerospace. In early 2023 the Excellion GmbH was founded to bring the latest innovations in battery cells and systems to the market. Since then we have grown into a multi-national team providing cutting-edge battery solutions to satellite manufacturers and launch service providers.
