Typical applications
The CompreFrame can be used to operate the test cells CompreCell 12, CompreCell 12-DP and CompreCell Pouch. Therefore, a broad range of different applications is accessible:
Cycling of solid-state batteries at precisely adjusted stack pressure and under active temperature control
Cycling of pouch cell formats with lithium-ion battery or solid-state battery chemistry at precisely adjusted stack pressure and under temperature control
Pressure- and temperature-dependent investigation of a solid-state electrolyte’s conductivity
Stripping-plating experiments under actively controlled stack pressure
Dilatation monitoring during cycling of pouch cells

Detailed Description
The CompreFrame is a cell stand for all types of CompreCells (CompreCell 6/12, CompreCell 12 DP and CompreCell Pouch) enabling very precise manual pressure application to solid electrolyte powders, pellets, all-solid-state batteries (ASSB), and pouch cells.
A display unit always shows the current force, making stand-alone operation possible. The force and sample temperature can also be recorded and monitored using the included CompreDriveControl software.
The CompreFrame offers automated temperature control, if used with the optional H- or HC Add-On. Different pressure sensors are available for best accuracy. If other spring assemblies should be required, please contact us to discuss customization options.
