EV battery testing - Separator film testing
Testing solutions necessary for evaluating separator materials that excel in safety and strength, contributing to the reduction of lithium-ion battery weight and improvement of energy density.
■Puncture Test The puncture test of the separator film is important for ensuring the safety and longevity of each cell throughout the battery's lifecycle. The film must have sufficient strength to withstand punctures from dendrites formed during long-term use. In this application, it is crucial to ensure proper tension of the test specimen and correct alignment of the upper contactor. The procedure for this test is similar to EN 14477 and ASTM F1306. ■Tensile Test The tensile test is used to confirm that the separator film can withstand all mechanical operations that occur during the manufacturing and use of the battery. To ensure reproducibility and productivity, and to prevent damage to the test specimen before testing, proper alignment, insertion, and gripping operations of the test specimen must be ensured. The procedure for this test is similar to ASTM D882 and ISO 527-3.
