Soft Pack Battery Industry SolutionsAs the smallest unit of the battery system, the battery cell's sealing integrity directly affects the safety performance and cycle life of the battery.Leakage of the electrolyte inside the battery core will lead to performance degradation, short circuit and even thermal runaway.Based on the special structure and process requirements of battery cells, Hirays provides professional and reliable sealing testing solutions to ensure that the battery core maintains excellent sealing performance during charge and discharge cycles.
We focus on the precise detection of the three core sealing parts of the battery cell:
Shell package sealing
Detect the integrity of aluminum-plastic film packaging or metal shell welding to ensure reliable sealing during long-term charge and discharge cycles.
Tab and case seal
Evaluate the sealing performance of the connection between the tab and the case to prevent electrolyte from leaking through the tab interface.
Functional integrity of the explosion-proof valve
Verify the sealing performance of the explosion-proof valve under the set pressure to ensure sealing reliability under normal working conditions.
Detection accuracy is as high as 10⁻¹¹ mb·L/s, accurately identifying micro leaks
Detection efficiency is increased by 4 times, single cell detection ≤6 seconds
Defect rate reduced to less than 50ppm
Operation costs reduced by 40%
