PROBLEM TO BE SOLVED: To improve injection efficiency and to reduce an installation area by injecting a fixed amount of an electrolytic solution into a battery container in which only inside the battery container is airtight blocked to contain an electrode by decompressing and pressurizing to impregnate into the electrode. SOLUTION: An injecting mechanism 120 brings an injecting mechanism special nozzle (blocked part) 130 in contact with an opening of a battery container K to airtight seal the inside of the battery container K, operates a pressure reducing device 151 to reduce the inner pressure of the battery container K to a fixed pressure, and then closes a pressure reducing holding valve 151. Then, opens an injection valve 142, moves an electrolyte solution W in a storage tank 143 into the battery container K by atmospheric pressure, and then switches to a pressurizing tank 171 to pressurize an electrolyte solution in the battery container K to impregnate into an electrode L. Thereby, as the electrolyte solution W can be efficiently injected into the battery container K as well as be impregnated into the electrode L to pressure reduce and pressurize only inside the battery container K, a small and inexpensive mechanism can be provided. |
