Abstract

The present specification relates to an embodiment of an electrode material winding apparatus, in which an electrode material is processed so that an electrode tab is not disposed in an impregnation region into which an electrolyte can be injected, and the electrode material is wound so that the electrode tab is arranged only in a specific region excluding the impregnation region, thereby winding the electrode material such that the electrolyte is injected through the impregnation region.
