About
Pentalys Energy develops materials for lithium-sulfur batteries, including a sulfur-based cathode material and a separator that blocks polysulfide migration.
The technology comes from more than a decade of membrane research at the Norwegian University of Science and Technology, NTNU, in Trondheim.
It targets applications where weight is critical, such as express boats, aircraft, drones and heavy-duty transport. The company signed a license agreement with NTNU in February 2026, moved its commercial activities to the Startuplab incubator in March 2026, and joined the FME BATTERY research centre. In 2026 the Research Council of Norway awarded it 5 MNOK to scale up its separator.
