LiBS – Lithium-ion Battery Separators

MARCHANTE’s Research & Development Team has improved the properties of Film Stretching for high performance separator film production.

Experts in Film Stretching for more than 40 years, our team has developed a reliable Simultaneous Stretching system, ensuring the productivity of your line for Lithium-ion Battery Separators. By using the most advanced technology for Battery Film Stretching, ensure homogeneous results and significant reduction of energy consumption. This flexible system will allow you to expand your production capacities and optimize the effective width of the final film.

A separator in a lithium-ion battery is a crucial component that separates the positive and negative electrodes, preventing short circuits and ensuring safe and efficient operation of the battery. The separator is made of a thin, permeable material that allows ions to flow freely between the electrodes while preventing electrical contact between them.

The role of the separator is to maintain the stability of the battery by preventing dendrite growth and other undesirable reactions between the electrodes. It also helps to regulate the flow of ions, ensuring that the battery can charge and discharge in a controlled and safe manner.

In summary, separators play a critical role in the safety and performance of lithium-ion batteries, and their quality and composition are critical factors in determining the overall reliability and longevity of the battery.

Our stretching lines are capable of stretching films with high precision, which ensures that the separators produced have uniform and consistent thickness, porosity  and mechanical properties. This is essential for ensuring the stability and reliability of lithium-ion batteries, as well as their ability to perform efficiently over time.
