Advanced Battery Coatings

Advanced battery technology

Advanced battery technology is becoming a core driving force for the global energy transition, supporting the development of electric vehicles and renewable energy storage. Current research focuses on overcoming the bottlenecks of traditional lithium-ion batteries in terms of energy density, cycle life, and safety. Solid-state, sodium-ion, and silicon-based anode batteries are becoming the mainstream directions, and innovative processes such as dry electrodes are accelerating industrial upgrading.

Ultrasonic spraying technology provides a precision thin-film coating solution for next-generation energy storage batteries, covering lithium-ion, solid-state, sodium-ion, and emerging aluminum-ion routes. Through ultrasonic atomization, highly uniform thin-film deposition can be achieved on the electrode and separator surfaces, particularly suitable for low-solids composite slurries, offering significant advantages in coating uniformity, low material loss, porosity control, and micron-level thickness repeatability.

Separator coating can improve battery safety, mechanical strength, and electrolyte wettability, extending cycle life; polyimide coating can prepare dense, defect-free micron-level thin films for precision electrical insulation of battery stacks, tabs, and busbars, providing non-contact deposition and gentle protection for sensitive substrates. Overall, ultrasonic spraying, with its controllable thin film deposition capabilities and excellent uniformity, has become a key enabling technology for the research and development and pilot production of next-generation batteries.
