EV battery testing - Separator film testing
AT3 Automatic Testing System, 9450 Drop Weight Impact Testing Machine, 6800 Series Universal Material Testing Machine
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.

basic information
■Friction Coefficient Test Tight winding operations generate mechanical loads between the separator film and the electrode coating. It is important to know the friction coefficient between these two surfaces. A precise understanding of the friction coefficient allows for proper execution of the winding process during manufacturing. Guidance for this test typically uses ISO 8295 and ASTM D1894-14. ■Puncture Resistance Test Against Impact Events The selection of materials for the separator film is essential to ensure the integrity of the battery. If there are issues with mechanical performance, the likelihood of internal short circuits increases, which can lead to thermal runaway. To choose materials that provide the best performance while reducing thickness and weight, puncture resistance testing against impact events is extremely important. ■Automated Testing Instron's automated system is a testing machine that can conduct battery tests with unprecedented levels of productivity. As battery production continues to increase, productivity and efficiency are crucial to meet demand. By combining recommended equipment and automated systems for each application, operator burden can be reduced while maximizing productivity and maintaining optimal results.

Company information
Instron was founded in 1946 by Harold Hindman and George Bahl, who were conducting joint research at MIT (Massachusetts Institute of Technology) at the time. They developed the world's first electromechanical (screw-type) universal testing machine. The name "Instron" is derived from "instrument" and "electronics." Instron's product range offers diversity that can cater to almost all global markets and industries, and since its establishment, over 70 years of testing technology and manufacturing experience have been built, with more than 50,000 systems operating worldwide. In 1965, Instron Japan was established to support customers in Japan. Currently, it has major bases in the United States, Europe, and Asia, providing sales and services in 40 languages through agents in 160 countries around the world.
