Products Description
The battery electrode comma blade coating machine is a state-of-the-art, high-precision coating system engineered for the new energy sector, including applications in lithium-ion batteries and supercapacitors. At its core, this advanced equipment utilizes a precision-engineered comma blade as the primary coating mechanism, enabling the uniform and accurate application of slurry onto conductive metal foils such as copper or aluminum. This process is crucial for forming high-quality battery electrodes, whether for anodes or cathodes. As a critical component in modern battery manufacturing, this sophisticated coating machine plays a vital role in the production processes of various energy storage devices, including lithium-ion batteries, supercapacitors, and fuel cells, making it an essential piece of equipment in contemporary battery fabrication facilities.
Product Features
High-precision coating
Comma blade scraping technology is used to ensure uniform coating thickness.
A wide range of coating thickness can meet different needs from 5 microns to 250 microns.
Versatile applicability
Applicable to a variety of slurries (such as positive electrode slurry, negative electrode slurry) and substrates (such as copper foil, aluminum foil).
Coating width and thickness can be customized according to customer needs.
Stable and reliable
Adopt high-precision transmission system and tension control system to ensure smooth operation of the substrate.
Key components (such as comma blade, drying system) are made of high-quality materials and are durable.
