An electrolyte injecting device is provided to improve an electrolyte injection rate markedly by using a high pressure chamber pressurization manner and achieve a balance between a pressure applied to an airtight chamber and a hopper-side pressure used to inject an electrolyte. An electrolyte injecting device(100) comprises: a pressurized chamber(110) which is placed to expose the surrounding upper part of at least one battery cell(101) including an electrolyte inlet(102) and has a wall capable of insulating the battery cell from the outside; an injection nozzle(140) which is installed to go through a part of the pressurized chamber wall outside the pressurized chamber and be connected to the electrolyte inlet of the battery cell, and is able to be directly united with the electrolyte inlet; an electrolyte hopper(150) to be joined to the injection nozzle; an electrolyte injection part which has a nozzle opening/closing valve(160); at least one first port(180) which is installed at one side of the electrolyte injection part outside the pressurized chamber and is able to be connected with at least one of an electrolyte supply line, a vacuum line, and a pressurized line; and at least one second port(190) which provides a vacuum or pressure synchronized with that of the first port to the inside of the pressurized chamber. |
