SPECIFICATIONS
The battery electrode comma blade coating machine is a high-precision, high-efficiency coating equipment designed for new energy fields such as lithium batteries and supercapacitors. It uses a comma blade as the core coating tool, which can evenly and accurately coat the slurry on metal foil (such as copper foil, aluminum foil) to form the positive or negative electrode of the battery. This battery electrode coating machine is widely used in the electrode manufacturing fields of lithium-ion batteries, supercapacitors, fuel cells, etc., and is an indispensable key equipment in the battery production process.
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.
