CompreFrame

The CompreFrame is a pressure frame for studying solid-state electrolytes, solid-state batteries, and small pouch cells under pressure and temperature control when used with the optional H- or HC-Add-On. As the little brother of the CompreDrive, it provides a versatile setup to operate test cells under precisely adjusted stack pressure and active temperature control.

• High-precision pressure adjustment and temperature control
• Broad accessible stack-pressure and temperature range
• For operating innovative test cell designs from coin-cell sized samples to small pouch cell formats
• On-demand: dilatation measurement, e.g. during cycling of pouch cells
• Powerful, trend-setting control software ensuring almost fully automated test procedure (force manually applied)

Typical applications

The CompreFrame can be used to operate the test cells CompreCell 6/12, CompreCell DP and CompreCell Pouch. A broad range of 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 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 rhd instruments to discuss customization options.
