Cell data reports

We’re committed to transparency

We try new things, test, fail, learn, and repeat.

SES AI believes in full transparency on this journey to a Li-Metal EV battery that will power a new era of electric transportation.


We regularly publish our own cell test data and results as well as cell data testing reports conducted independently by third-parties.


We will continue to publish data reports regularly to keep the industry updated as we improve everything from materials to engineering to manufacturing quality.
