The potential risks of ignoring battery airtightness testing
In new energy battery systems, poor airtightness is a significant factor leading to performance degradation, shortened lifespan, and even safety incidents. Many companies neglect airtightness testing during maintenance, resulting in problems such as electrolyte leakage, accelerated capacity decay, and thermal runaway. For example, an electric logistics vehicle company experienced excessive cycle degradation in multiple vehicles within just six months due to substandard battery pack airtightness, causing direct economic losses and damage to its brand reputation. The root cause of these problems lies in the lack of accurate airtightness testing and maintenance tools.
The Importance of Precision Airtightness Testing Equipment
How to test the airtightness of a battery?
Battery airtightness testing is primarily conducted using pressure differential, helium, or gas tracer methods. Traditional methods suffer from low accuracy and complex operation, making it difficult to meet the efficiency and reliability requirements of B2B companies. Precision airtightness testing equipment, through a mobile leak detection system , enables rapid and traceable end-to-end testing, ensuring that the sealing of each battery cell meets standards.
Precision airtightness testing method
Pressure decay method : By applying pressure inside the battery, observing the pressure changes caused by leakage, the leakage rate is calculated.
Helium tracer detection method : Helium gas is used as the detection medium, combined with a high-sensitivity helium mass spectrometer to locate tiny leak points.
CTP technology application : Utilizing Solid Energy’s CTP technology to efficiently inspect the sealing structure of battery packs and quickly identify potential leakage hazards.
