Altech Advanced Materials AG has initiated the liquidation of its subsidiary, Altech Batteries GmbH, following the termination of the CERENERGY project. The project, which focused on producing ceramic solid-state batteries for stationary power grids at the Schwarze Pumpe Industrial Park, was halted due to insufficient secured financing. As part of the winding-down process, Altech is selling the land acquired for the plant back to the municipality of Spreetal for 675,000 euros.

The failure of the project reportedly followed the refusal of a debt waiver by the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS), which held a 25 percent stake in the venture. Consequently, Altech Batteries GmbH is facing insolvency and plans to file for bankruptcy. Amidst this restructuring, Enapter AG has proposed the re-election of Eva Katheder to its supervisory board; Katheder is a member of the supervisory board at Altech Advanced Materials AG.
