Abstract

The present invention relates to a secondary battery and, more particularly, to an electrolyte injection device for injecting an electrolyte into a pouch for sealing a secondary battery. Disclosed is an electrolyte injection device for a secondary battery (10) of a plate-like structure which comprises: a secondary battery cell (20) in which a first electrode sheet (13) and a second electrode sheet (14) are stacked alternately and a separator (12) is disposed between the second electrode sheet (13) and the second electrode sheet (14); and a pouch (11) for sealing the secondary battery cell (20) impregnated in an electrolyte, the electrolyte injection device comprising: a battery supporting part (100), installed to be movable up and down, in which at least one secondary battery (10) is loaded so that the normal of a plate surface is arranged horizontally with the upper side of the pouch (11) open; an upper housing (200), having an open lower side, which forms an internal space (S) sealed together with the battery supporting part (100) when the battery supporting part (100) is moved upward; a pressure control part (300) for converting the pressure of the internal space (S) between the atmospheric pressure and a preset vacuum pressure in a state where the battery supporting part (100) is moved upward and the internal space (S) is sealed; and at least one electrolyte injection part (410), installed in the upper housing (200), which includes at least one nozzle part (410) to be inserted into the secondary battery (10) when the battery supporting part (100) is moved upward, and injects an electrolyte when the pressure of the internal space (S) drops to the vacuum pressure.
