The solid-state pressing device enables the direct pressing of powdered solid-state cell stacks in the PAT-Solid-Core. The individual components of the solid-state cell stack – cathode (CAM), electrolyte (SE), and anode (here InLiIn) – are filled into the PAT-Solid-Core in separate steps. The PAT-Solid-Core is then inserted into the Solid-State Pressing Device, which seals the cell stack airtight, thereby enabling the respective components to be pressed either inside or outside the glovebox using a separate press.

Each layer can be pressed with a maximum weight of 5 tonnes. Once the pressing steps are complete, the PAT-Solid-Core is removed again from the Pressing Device and inserted into a compatible battery test cell for cycling.
