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.
Claims8
A method of coating an active material for a secondary battery in which the active material is coated onto an electrode current collector of the secondary battery, the method comprising:
- disposing a guide member on each of a left and right side 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,
- wherein the moving direction of the electrode current collector is in a linear direction by a first roller rotating in a first rotating direction, and
- wherein the method further comprises a process in which the guide member is moved by a second roller at both ends of the guide member that rotates along a second rotating direction that is an opposite direction to the first rotating direction;
- wherein the second roller allows the guide member to travel in place, and
- wherein the guide member is disposed on each of a left and right side based on a moving direction of the electrode current collector upstream of coating the active material.
