Dielectric Layer Coatings for Lithium-ion or Other Types of Battery Manufacturing
Ultrasonic coating systems are used for polyimide or similar chemistry coatings to create encapsulating layers in applications requiring a chemically inert protective coating. Polyimide coatings can replace Kapton tape for difficult geometries and smaller areas (channels, holes), encapsulating materials and protecting Lithium and other hazardous materials from unwanted reactions or leaks. For batteries using radioactive or highly reactive elements, polyimides are used as flexible encapsulation materials with good structural integrity.
Other types of battery layer coatings that can be applied with ultrasonic spray include:
- Separator films to prevent overheating, increase safety and extend battery life
- Layers to reduce dendrite formation
- Functional metal oxide coatings onto anode or cathode layers to enhance performance and increase efficiency
- Various layers to enhance or create desired porosity
Benefits of using ultrasonic spray for battery layer coatings include:
- Durable, mechanically stable layers
- Nozzles have no moving parts to wear out
- Desirable dielectric properties
- Extensive expertise with polyimide coatings
- Extensive experience coating microporous membranes
- Very uniform thin films with high repeatability
- High temperature resistant coatings perform in temperatures up to 400 degrees C
