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

Typical applications

Understanding the mechanical behaviour of battery cells during cycling is a critical factor. If mechanical characteristics are not taken into account, battery research can end up with irreproducible results and, even worse, with issues when trying to transfer the obtained results to the module and pack level. Typical applications with the advanced pouch cell testing fixture ComprePouch are:

• Cycling of pouch cells at spring-loaded stack-pressure, mimicking flexible installation situations
• Cycling of pouch cells at pseudo-fixed volume, mimicking constrained installation situations
• 2D pressure mapping while cycling at different conditions
• Quantifying pouch cell breathing and swelling during cycling
• Improving reproducibility by well-controlled measurement conditions
