Next Generation Battery Thin Film Coating Solution

Next Generation Battery Thin Film Coating Solution | Ultrasonic Coating Technology | Cheersonic

Ultrasonic spraying technology provides precision thin film coating solutions for the next generation of energy storage batteries, covering various battery routes such as lithium-ion, solid-state, sodium ion, and emerging aluminum ion. Through ultrasonic atomization technology, highly uniform thin film deposition can be achieved on the surface of electrodes and separators, effectively improving battery performance, safety, durability, and cycle life.

This technology is particularly suitable for precision coating of low solid content composite slurries, which is different from traditional high solid content thick slurry processes. In the research and development and emerging mass production stages, coating uniformity, low material loss, porosity control, and micrometer level thickness repeatability are crucial, and ultrasonic spraying has significant advantages in these aspects. The material systems that can be processed include graphite, carbon nanotubes, various positive electrode oxides, ceramic separator coatings, polyimide and dielectric barrier coatings, positive and negative electrode coatings, and porous carbon electrode coatings.

In terms of membrane coating, uniform membrane coating can improve battery safety, mechanical strength, and electrolyte wettability, directly extending cycle life and enhancing thermal stability. Ceramic and polymer composite coatings maintain the integrity of the diaphragm structure at high temperatures, preventing shrinkage or melting through. Ultrasonic spraying achieves thin and consistent membrane coatings without damaging the porosity and ion transport channels of the membrane, while flexibly adjusting the porosity, thickness, and composition to meet specific electrochemical performance goals.

In terms of polyimide coating, ultrasonic spraying can prepare dense and defect free polyimide films with a thickness of micrometers or even sub micrometers, which are used for precision electrical insulation of battery stacks, electrode lugs, and busbars. Non contact deposition can be gently coated on sensitive foils, nanofiber membranes, and polymer films to protect substrate integrity. Dense and uniform thin films can effectively reduce the risks of short circuits, leakage, and arcing in high-voltage components, especially suitable for scenarios in solid-state and hybrid battery systems that require strict requirements for uniform barrier layers and controllable morphology.

Overall, ultrasonic spraying has become a key enabling technology for the development and pilot production of next-generation battery materials due to its controllable thin film deposition ability, excellent uniformity, pore retention rate, and low material loss.
