LASIBAT - Laser-based in-line sintering of adapted ceramic materials for the manufacturing of solid-state battery cells

The objective of the LASIBAT project is to enable a new inline manufacturing process for the ceramic cathode and electrolyte layers of future solid-state batteries.

The performance of conventional lithium-ion batteries is limited by technical and safety design choices. An alternative to conventional lithium-ion batteries is the solid-state battery, where a solid electrolyte layer replaces the organic solvent and the separator in the middle of the battery.

Solid-state batteries are however challenging to manufacture due to long sintering steps at high temperatures which are time and energy consuming and can cause reduced electrochemical performance. In LASIBAT, a scalable inline laser sintering process is developed for the manufacturing of solid-state batteries.

As laser sintering can be integrated in a continuous production process it is highly relevant for use in production of solid-state lithium-ion batteries for automobile applications or portable devices. An important part of the project is the development of functional ceramic materials that are adapted to the laser sintering process. In addition to developing knowledge about manufacturing solid-state battery materials, the project will create a new market potential for European battery manufacturers as well as companies producing and developing laser system technology.

SINTEF will adapt ceramic cathode and electrolyte powders made by Cerpotech for film deposition, deposit films for later laser sintering at Fraunhofer ILT, and characterize the electrochemical performance of the developed batteries.
