How to do leak test for lithium battery ?

In recent years,the new energy vehicle industry has grown rapidly, and the domestic demand for power batteries has also increased.The number of power lithium battery manufacturers is increasing, and the production process is gradually standardized and process oriented. The safety of lithium battery is the focus of major manufacturers and consumers, especially the packaging and compression resistance of the battery.

Lithium battery is made of lithium metal or lithium alloy as positive and negative electrode materials,and using non-aqueous electrolytic solutions (mostly organic volatile solvents, VOCs).

Square power battery

If the encapsulation and compression resistance of the battery are not well done, liquid leakage will occur, endangering the human body and the environment. How can manufacturers prevent leakage of lithium batteries?

First of all, we need to understand the types of lithium batteries, which are roughly divided into two types in the market:

1. Lithium batteries for mobile phones, watches, and other consumer electronics

Consumer electronics lithium battery

2. Square / cylindrical power battery

As show in the above picture

l In the production process, the non-hydrolytic solvent is injected into the shell of the battery for encapsulation.

l In order to prevent liquid leakage, it is necessary to conduct VOCs gas leakage testing before the lithium battery leaves the factory.

l What is the function of lithium battery leak test system? What is included?

l The leak test system can determine whether the concentration of organic volatiles in the electrolyte reaches the set upper limit, including instruments, tooling and molds.

Lithium battery leak detection solution

1: The equipment used for testing - HV-01 is suitable for most consumer electronic batteries: mobile phones/watches/laptops, etc.
