The next generation of solid-state battery test cells - the CompreCell 12 DP
The CompreCell 12 DP is a measuring cell designed for use with the CompreDrive active press system. It is airtight and can therefore be used to handle sensitive samples by filling the cell in a glovebox under inert gas atmosphere and then measuring it outside.
The CompreCell 12 DP is a measurement cell suitable for measuring stack-ups of solid samples, like all-solid-state batteries, under active pressure control. Further it is also suitable for powdered samples and allows e.g. pelletizing in-situ.
An intuitve design facilitates the layer-by-layer assembling of an all-solid-state battery starting from the separate component materials:
Both hard-metal plungers in the cell can move independently and therefore apply pressure to a stack at a fixed z-location in the inner sleeve. This allows for measuring stack-ups that are sensitive to vertical movement and minimizes the risk of short-circuits over the layers. As sleeve material, AlOx, PEI, and PEEK are available .
The fixed location of the sample also facilitates the use of a solid-state reference electrode for 3-electrode measurements .
The CompreCell 12-DP is available in three different variants for materials and diameters:
- 840340: 12mm sample diameter, PEI inner sleeve.
- 840341: 12mm sample diameter, PEEK inner sleeve
- 840342: 12mm sample diameter, ceramic inner sleeve
