Abstract: The present disclosure provides a method for manufacturing a unit cell including the steps of: preparing an electrode and a separator individually, wherein the separator includes a porous polymer substrate and a porous coating layer disposed on at least one surface of the porous polymer substrate and including a mixture of inorganic particles with a binder polymer; applying a lamination solvent to the surface of the separator to be bound with the electrode; and carrying out lamination of the electrode with the separator before the lamination solvent is dried. The method according to the present disclosure can solve the problem of shrinking of a separator occurring in the conventional lamination process.
