Spring-loaded 30 kN pressure frame

The CompreFrame is a cell stand for all types of CompreCells (CompreCell 6/12, CompreCell 12 DP and CompreCell Pouch) enabling manual pressure application to solid electrolyte powders, pellets, all-solid-state batteries (ASSB), and pouch cells

A display unit always shows the current force values (stand-alone operation possible), but stack pressure and sample temperature can be recorded and monitored using the CompreDriveControl software. 

The CompreFrame offers automated temperature control, if used with the optional H- or HC Add-On

Different spring assemblies and pressure sensors are available for best accuracy.

Typical Applications:

  • Pressure dependent and temperature dependent measurements of pelletized or powder-like solid electrolytes to determine the conductivity
  • Stripping/plating experiments of solid electrolyte pellets sandwiched between two Li metal electrodes at well-defined pressures and temperatures
  • Cycling of all-solid-state batteries at well-defined stack-pressures and sample temperatures
