Detailed Description

The CompreCell 6/12 is a test cell designed for use with the CompreDrive or CompreFrame setup. The CompreCell is used in solid-state electrochemistry to investigate materials such as solid electrolytes or solid-state batteries with common electrochemical methods while keeping the sample under defined compression and temperature.

The CompreCell is airtight (helium-leakage tested up to +250 °C!) 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 force is applied via hard-metal plungers that are inserted into an inner sleeve that is commonly made from an AlOx-ceramic for maximum force resistance. The sleeve may also be manufactured from other materials such as PEI or PEEK, which may limit the maximum temperature that may be applied to the cell.

The default sample diameters are 12 mm or 6 mm, but other diameters might be available on demand. Likewise, the maximum force may be limited, due to the increased pressures produced at smaller diameters.
