ComprePouch

A versatile stand-alone pouch cell fixture for testing pouch cells

The ComprePouch can be used to operate your pouch cells under different conditions regarding the applied pressure and temperature. The applied pressure can be monitored and recorded. At the same time, you can follow thickness changes of your pouch cell, either induced by charging and discharging the battery and/or by applying pressure.

  • Switch between pseudo-constant volume and spring-loaded mode
  • Follow pressure and thickness changes during cycling
  • Large accessible pressure and temperature range
  • Small foot-print and low height: Parallelize your measurements
  • 2D pressure mapping in combination with e.g. TekScan sensors
Pouch cell fixture for testing battery pouch cells.

To 25kN applied force.

The ComprePouch is a cell fixture that enables electrochemical tests of batteries in a pouch cell format at different stack-pressure conditions. It allows for switching between pseudo-constant volume and spring-loaded pressure conditions. As an option it integrates a force sensor, that shows the applied force on an attached display and/or a connected PC. Further options include precise in-situ thickness measurements allowing for a cell breathing and swelling analysis in the spring-loaded mode.
Force is applied by four nuts compressing tension springs. Force is transferred through massive, guided metal plates, and optionally a force sensor, to your sample. The springs can easily be exchanged by ones with different rates, or by stiff cylinders.
The measured force can be shown on a display and/or monitored and stored via a connected PC. You can use all data handling and plotting features that our CompreDriveControl Software offers. The sample temperature can be controlled by placing the ComprePouch inside a temperature chamber.

  • High quality setup for testing pouch cells
  • Different spring packages available to switch between pseudo-constant volume and spring-loaded mode (pseudo-constant pressure)
  • Option to follow thickness changes
  • Large range of applicable force up to 25 kN
  • Large range of sample temperature from -30 °C up to 90 °C (in climate chamber)
  • Universal compatibility with all potentiostats/galvanostats/battery cyclers
