| 摘要 |
<p>The present invention relates to a porous separation membrane comprising a patterned binder layer, an electrode assembly comprising the separation membrane, and a method for manufacturing the separation membrane. According to an aspect of the present invention, provided is a porous separation membrane, comprising a porous substrate and a patterned binder layer that is applied to at least one surface of the porous substrate and includes a non-coating region, wherein the thickness by which the binder layer is applied thereto is 0.1 to 10 μm. According to another aspect of the present invention, provided is a method for manufacturing a porous separation membrane. The method comprises: a step for forming a binder solution; a step for forming a patterned binder layer; a transfer step; and a press step. According to an embodiment of the present invention, a porous separation membrane has porosity, a uniform thickness, and excellent durability, and can be coupled to an electrode with an excellent binding force and high ion conductance.</p> |
