Coating Machine Lithium Ion Baattery Assembly Machine 360 Type Electrode Slurry Coating Machinery
Ⅰ.Introduction:
The intermittent experimental coater is a three-roll transfer coating equipment, which can be used for continuous and intermittent coating, and is convenient to apply to various substrates for surface coating processes. Especially used in the lithium-ion battery industry. The equipment is designed to be convenient for researchers to use, and to meet the requirements of coating precision and consistency, which is no different from production, and has an excellent drying effect. It is ideal for research and development and small trials of lithium-ion batteries, super capacitors, nickel batteries and other secondary batteries.
