Most fire accidents in various products using lithium-ion batteries, including electric vehicles, occur while charging. The main reason for this is that the negative electrode material (graphite or mixed silicon) continues to inflate (Figure 1) after repeated charging cycles, shortening the distance between the positive and negative electrodes. This results in the effective distance between these electrodes becoming shorter than the original design due to electrode burrs or metal particles, increasing the risk of an internal short circuit.

of a lithium-ion battery(Furukawa Electric Review, No. 134 2015-1)

Therefore, from a fire protection perspective, insulation tests of lithium-ion battery cells should check the distance between electrodes, rather than measure the insulation resistance. From the air breakdown voltage v.s. distance data (Figure 2), we can see that, even if the gap distance is as short as several μm, the breakdown voltage is higher than 350V, so the insulation withstand voltage test should be conducted at a voltage higher than 350V. Testing for the occurrence of breakdown or flashover enables an effective assessment of whether the insulation distance is sufficient (Figure 3).

Figure 2 Relationship between air breakdown voltage and distance

Figure 3 Electrical flashover during testing

Besides fires, another hazard to be considered is excessive self-discharge caused by conductive impurities (leakage current) inside the separator. The testing voltage of this part need not be too high, and it takes a long time to wait for the real leakage current to become apparent. CHROMA 11210's +Flash test function provides two-stage intermittent high and low voltage tests, which allow customization of timing sequence, sampling integration time, measurement ranges and defective judgment conditions, fully meeting the requirements of these two aspects of insulation quality inspection of lithium-ion battery cells.

Chroma 11210 battery cell insulation tester uses unique electrical flashover detection technology and its built-in +Flash test function for lithium-ion batteries (dry cells) to detect the sufficiency of the effective insulation distance before electrolyte filling and to detect any abnormal electronic leakage current. This effectively reduces the risk of lithium-ion battery fires and prevents products with potential insulation defects from entering the next production stage or even the end market.
