CompreCell Pouch

Innovative fixture for testing pouch cells at different stack pressures and temperatures

Benefit from this cell fixture, specially developed for the electrochemical characterisation of batteries in pouch cell format.

  • Forces of up to 75 kN can be applied
  • Broad accessible temperature range from 0 °C to +100 °C
  • Can be combined with distance add-on to measure the pouch cells dilatation during charging and discharging
  • Compatible with CompreDrive and CompreFrame

Typical applications

The CompreCell Pouch 10S HC combined with the CompreFrame or CompreDrive is the ideal solution for controlling the stack pressure and temperature of batteries in a pouch cell format. That opens the door to intriguing applications:

  • Cycling of solid-state batteries and lithium-ion batteries under active stack pressure and temperature control

  • Monitoring of thickness changes of pouch cell format batteries during cycling

Detailed Description

The CompreCell Pouch 10S HC is a fixture developed for use with the CompreDrive and the CompreFrame setup. It is designed to enable the electrochemical characterization of pouch cell format batteries using common electrochemical methods while precisely regulating the applied force (stack pressure) and temperature (external circulator needed).

The CompreCell Pouch 10S HC can be operated in combination with every available potentiostat/galvanostat model. The cell employs a solid stainless-steel body with a square sample stage (e.g. 10 cm x 10 cm for 10S variant). The rated maximum applicable force is 75 kN. The rated maximum sample height is 20 mm (10 mm when being combined with the CompreFrame). Furthermore, with this setup cell temperatures between 0 °C and +100 °C can be realized (external circulator needed). A drip pan ensures to catch any condensed water.

The CompreCell Pouch 10S HC remains in the CompreDrive / CompreFrame between measurements and does not need to be moved to change the cell under test.
