In recent years, with the rapid increase in the development momentum of new energy, the lithium battery industry has also developed and grown. However, the performance and safety of lithium batteries cannot be ignored; everyone in the lithium battery industry knows that the wettability and wetting speed of the separator are important for lithium batteries. The operation of the ion battery is very important, so it is necessary to use a contact angle measuring instrument to measure the surface properties such as the wettability of the separator, which is helpful for quality control and product development.

We know that hydrophilic materials have better wettability than hydrophobic materials, and the wettability of the separator is related to the wetting speed, that is, the better the wettability of the separator, the smaller the electrolyte contact angle, so the contact The angle tester measures the contact angle between the surface of the lithium battery separator and the electrolyte, and the wettability can be directly judged by the size of the contact angle.
