摘要： A liquid injection device includes a liquid injector including a liquid injection hopper connected to a storage tank configured to store an electrolyte and a valve including an injection nozzle connected to the liquid injector to inject the electrolyte into a cell. The injection nozzle includes a conical body and an injection part protruding from an end of the body, and the injection part includes an obstacle. A shape of the liquid injection nozzle may be changed to disperse an injection pressure of the electrolyte, and damage such as scratches in a top surface of the electrode assembly may be avoided.
