Open Battery Day 2021 at HIU

Open Battery Day 2021: September 18th, 2021, 10 a.m. until 6 p.m.

There was not only a lot to show, but also a lot to celebrate: Exactly 10 years ago, in 2011, the Helmholtz Institute in Ulm (HIU) was founded. Since then, top international research and development of electrochemical cell and battery concepts of the next generation have been taking place at the HIU. The international team of around 130 scientists has been researching the development of sustainable energy storage systems for stationary and mobile use.


On the "Open Battery Day 2021" there was a lot to discover and learn: every 90 minutes there was a lecture on battery research followed by a guided tour of the laboratory. This laboratory tour was accompanied by employees of the HIU. So visitors were able to ask all the questions that moved them. 

In between HIU presented  films about and from the Helmholtz Institute Ulm on topics such as battery recycling, new battery materials (beyond lithium and cobalt) and electromobility in general.
