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.
