Secondary BatterySealing Pressure Distribution Measurement in Degassing Equipment

Application of Kitronyx's Pressure Distribution Measurement System for Degassing Process


This is a case study of measuring the pressure distribution during pressurization for sealing in the degassing and sealing process, conducted at room temperature.


This is the result of measuring the pressure distribution during the sealing process, conducted at room temperature.

It allows for the verification of the areas and shapes being pressurized by the equipment during sealing, ensuring that the equipment is performing uniform sealing.

Expected Benefits and Applications 

1. Ensuring Stability
Uneven sealing can lead to electrolyte leakage, posing safety risks. By measuring and correcting the uniformity during sealing, we can prevent electrolyte leaks and block the intrusion of external air or moisture.

2. Preventing Performance Degradation and Ensuring Durability

Uneven sealing can cause electrical performance degradation. Proper sealing ensures uniform battery capacity and output, preventing damage to the battery cells.
