Lithium battery

Lithium battery electrode coating is one of the important processes that affect the performance of lithium battery. Its principle is to coat a thin film on the surface of the active material of the positive and negative electrodes of the lithium battery to protect the electrode material and improve the cycle life and safety performance of the battery. Common coating methods include scraping coating, roll coating transfer, slit extrusion, among which slit extrusion coating is an advanced predicted amount coating technology, you can obtain high-precision film coating, fast speed, high precision, uniform thickness, this link requires high precision and reliability on the core parts of the equipment coating die head.
