Abstract: A method for manufacturing an electrode for a rechargeable battery includes, with reference to a center axis that divides a metal sheet left and right, setting a first coating line that is parallel with the center axis at a location deflected to one side, and a second coating line that is parallel with the center axis at a location deflected to the other side so as to correspond to the first coating line with reference to the virtual center axis and coating an electrode slurry on the metal sheet while alternately moving a slot die to the first coating line and the second coating line.
