CompreFrame

Pressure frame for studying solid-state electrolytes and solid-state batteries under pressure and temperature control

CompreFrame, the little brother of the CompreDrive: Benefit from a versatile setup to operate test cells for researching solid-state electrolytes and solid-state batteries under pressure and temperature control.

High-precision pressure adjustment and temperature control
Broad accessible stack-pressure and temperature range
For operating Innovative test cell designs for 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 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.
