6 FAQs about [Comparison of new energy battery puncture test]

How to test a battery separator with a pneumatic puncture test fixture?

Using a footswitch for actuation of the pneumatic grips frees the hands of the operator so securing of the battery separator is fast and efficient. To ensure stability and efficiency in the puncture test of the battery separator, the materials tester combined with a pneumatic puncture test fixture is the ideal solution.

Can a 120ah battery be used for a nail penetration test?

In this work, we have established an experimental platform for nail penetration tests to conduct a series of comparative penetration tests with a 120Ah battery, thereby simulating ISC events to verify the influence of various experiment settings on the voltage and temperature of large-capacity lithium-ion batteries.

Is nail penetration a reliable test for lithium-ion battery safety?

Lithium-ion battery safety evaluation covers a broad spectrum of abuse conditions. One of the popular testing methodologies is nail penetration. However, the reproducibility of nail penetration tests is rather poor, which compromises the credibility of the results.

Why does a battery stay inert after a puncture test?

When the researchers subjected their battery to puncture tests at the tip of a needle, the battery stayed inert and continued to function normally afterward. Several factors are credited for the battery’s puncture resistance. For one, the electrolytes are nonflammable.
