The Vertical Double Side Coating Machine is a core equipment for the manufacturing of lithium battery electrode sheets. It is specifically designed for performing synchronous double-sided coating operations on electrode substrates (such as copper foil and aluminum foil), serving as a crucial process equipment that connects the pre-treatment of the substrate with the drying of the electrode sheet. Its core function is to evenly coat the positive and negative electrode pastes on both sides of the substrate, forming an active material layer that meets the thickness requirements, providing the basic structure for battery energy storage and conduction.

Core feature

2.With a vertical coating architecture and a high-precision extrusion coating head, it can effectively avoid issues such as slumping of the slurry and residual bubbles.

3.Equipped with an intelligent tension control system and an online thickness monitoring module, it can adjust the coating parameters in real time, adapting to different viscosities of the slurry and substrate specifications.

4.The equipment has strong operational stability, supports continuous production, and is convenient for type change and adjustment, meeting the diverse needs of power, energy storage, and consumer lithium batteries.

Core function

1.Ensuring the uniformity and consistency of the coating on the electrode sheet, which directly affects the capacity, cycle life, and safety performance of the battery.The double-sided synchronous processing mode shortens the production process.

2.substrate damage, and significantly improves the production line capacity and product qualification rate.

3.Precisely controlling the coating thickness and surface density helps the battery achieve high energy density and lightweight design, meeting the performance requirements of various lithium battery applications.
