Abstract
A method of manufacturing a unit cell having a negative electrode, a separator, and a positive electrode are stacked and placed between guide rollers. One of the positive electrode and the negative electrode. The separator is coated with a binder, and the separator is dipped in a solvent to soften a cured binder before the separator is put between the guide rollers. An apparatus for manufacturing a unit cell includes a reservoir in which at least two or more transfer rollers that rotate while the separator passes therethrough are mounted, and a solvent is stored at a predetermined level; and a chamber into which the separator passing through a reservoir is put together with the positive electrode and the negative electrode. Guide rollers are disposed so that the negative electrode and the positive electrode move to both surfaces of the separator, respectively.
