Description
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.
