Abstract
A method of coating an active material for a secondary battery according to one embodiment of the present disclosure is a method of coating an active material on an electrode current collector of a secondary battery, the method comprising the steps of: disposing a guide member on each of the left and right sides based on a moving direction of the electrode current collector, and coating the active material onto the electrode current collector between the two guide members.
Claims5
An apparatus for coating an active material for a secondary battery, the apparatus comprising:
- a first roller adapted to move an electrode current collector in a moving direction,
- a guide member disposed correspond to a non-coated portion of the electrode current collector,
- a second roller located respectively at both ends of the guide member configured to rotate the guide member in place, and
- a coating machine adapted to coat the active material on a coated portion of the electrode current collector,
- wherein a rotating direction of the first roller and a rotating direction of the second roller are opposite to each other, and
- wherein the coating machine is disposed after the second roller, in the moving direction of the electrode current collector.
