6 FAQs about [Principle of lithium battery leakage detection device]

What is lithium-ion battery leak-detection?

This breakthrough leak-detection technology for all types of lithium-ion battery cells represents the single most important leak-detection development in the past 10 years, not just for the automotive industry but for the makers of smart phones, computers, consumer-electronics products and a variety of medical devices as well.

Why is low detection limit important for lithium battery leakage detection?

As known, the leakage of lithium battery (LIB) electrolyte is an important cause for runaway failure of LIB, so it has great significance to develop an approach for electrolyte leakage detection with low detection limit and fast response.

Can a lithium ion battery sensor be used to monitor leakage?

Based on the above results, we believe that the sensor can be used to monitor the leakage of lithium ion battery electrolyte, and has great potential in lithium battery safety applications. Chengao Liu: Conceptualization, Investigation, Methodology, Validation, Writing – original draft.

Can IC-MOF detect lithium-ion battery electrolyte leakage?

How does a battery leak test work?

Battery cells or housings are filled with helium and placed into a vacuum chamber. A leak-detection system can then measure the amount of helium leaking from the component being tested. Over a given period of time, a leak rate can be determined. For this type of test, a leak rate of 10-6 mbar∙l/s is normally used.

Can a battery sensor detect a leaking battery?

Real-time detection was further demonstrated by testing an actual LIB displaying electrolyte leakage. The sensor was able to signal the leakage while the voltage of the leaking battery was kept at almost the same level as that of a pristine battery for several hours, which shows the capability of hours of early warning time for our sensors.
