Lithium-Ion Batteries

Plasma surface pre-treatment solutions for the lithium-ion batteries manufacturing industry are engineered to enhance surface cleanliness, activation, and adhesion at critical production stages. Both atmospheric and vacuum plasma systems are used to remove organic contaminants, residual binders, and oxides from components such as aluminum and copper current collectors, electrode sheets, battery housings, and busbars. This surface activation significantly improves wettability, ensuring uniform slurry coating and strong bonding during lamination and assembly processes.

Atmospheric plasma systems can be integrated directly into roll-to-roll electrode production lines for continuous, high-speed treatment, while vacuum plasma systems provide highly uniform batch processing for complex or precision components. Plasma treatment also enhances adhesion for sealing, potting, and thermal interface materials used in battery modules and packs. As a dry and environmentally friendly technology, it reduces dependence on chemical cleaning agents and supports cleaner manufacturing environments.

With precise control and repeatable results, plasma surface treatment helps manufacturers improve cell consistency, increase production yield, and meet strict safety, durability, and performance requirements in EV and energy storage applications.

Keylink Technology offers advanced plasma surface treatment solutions for the lithium-ion batteries manufacturing industry by providing customized atmospheric and vacuum systems that optimize surface cleanliness, enhance coating and bonding performance, and seamlessly integrate into high-speed production lines to improve cell reliability and yield.
