Performing a peel test on the coating of the lithium-ion battery will ensure that the finished product is uniform and reliable. Using the materials tester with a customized grip will ensure stability throughout the entire peel test.
The coating quality of a lithium-ion battery separator is directly related to the performance of the battery's electrical properties. The peel strength test can not only effectively identify the coating quality and show the coating strength and uniformity, it can also guide the production line in regards to the adjustment of the coating.
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.
