<p>A battery case is disposed in a decompression chamber. An electrolyte in an aeration tank is injected into the battery case in the decompression chamber using a liquid injection nozzle. By exposing the electrolyte to an ambient pressure in the decompression chamber within the aeration tank before supplying the electrolyte to the liquid injection nozzle, a pressure of the electrolyte is regulated to a pressure in the decompression chamber, and gas molecules in the electrolyte are separated therefrom. By providing the aeration tank, an efficiency with which the gas molecules are separated from the electrolyte is improved, and as a result, the electrolyte is injected into the battery case smoothly.</p> |
