Abstract
The present invention relates to an electrolyte injection device including a base portion on which a preliminary battery cell is disposed on an upper surface thereof, a movable pressing jig attached to the base portion, and an electrolyte injection pipe configured to inject an electrolyte into the preliminary battery cell, wherein the movable pressing jig includes a portion configured to press the preliminary battery cell in a direction perpendicular to an upper surface and a lower surface of an electrode assembly receiving portion of the preliminary battery cell, and thus it is possible to prevent a phenomenon in which a separator is folded or peeled off even when an electrolyte injection rate is high.
