Abstract:
An electrode with a porous binder coating layer may be manufactured in a method including (S10) a step of preparing the electrode including an active material layer formed on at least one surface of a current collector; (S20) a step of acquiring a binder emulsion by adding a binder to a dispersion medium; and (S30) a step of coating the binder emulsion acquired at the step (S20) on a surface of the active material layer of the electrode in a screen printing method using a mesh to form a binder coating layer of a porous structure.
