What is a large lithium battery coating machine?

Product Structure

A lithium battery coating machine primarily consists of the following components:

Unwinding Unit: Used to hold the metal foil awaiting coating;

Coating Unit: Applies the positive and negative electrode materials uniformly onto the metal foil;

Drying Unit: Used to dry the metal foil after coating;

Winding Unit: Used to collect the coated metal foil.'

Working Principle

The working principle of a lithium battery coating machine is primarily realized through the following steps:

The metal foil awaiting coating is placed onto the unwinding unit;

The metal foil passes through the coating unit, where the positive and negative electrode materials are uniformly applied onto the foil via the coating head;

The coated metal foil enters the drying unit, where it is dried using methods involving heating or airflow;

The dried metal foil is collected by the winding unit.
