An injecting head of a high-speed electrolyte injecting device is provided to inject an electrolyte solution at high speed by using both a piston pressurization method and an air pressurization method and perform an efficient injection process. A injecting head of a high-speed electrolyte injecting device comprises: a first hopper(110) in which an electrolyte solution inlet(112) is formed at one side thereof and is provided with an electrolyte solution, a first port(111) is formed at the other side thereof to provide vacuum, pressure, or air exhaust, and the lower end thereof is tapered; a center pin(120) which is provided inside the first hopper, is installed to move up and down, and opens and closes the lower end of the first hopper; a second hopper(130) which covers the lower part of the first hopper and allows the first hopper to move up and down; and an injection nozzle(140) which is joined to the lower end of the second hopper to hug an injection hole(218) of a battery cell(217). |
