It is in a closed state. Thereby, at the time of pouring, the electrolyte passage 19 and the pressure reducing passage 28 are reliably shut off.
- the liquid injection device 2 has two seal mechanisms consisting of the main seal mechanism 10 and the sub seal mechanism 11, and after evacuation, a bag-like laminate film is formed by the pair of elastic bodies 41 and 42. After releasing the seal by the pair of elastic members 35 and 36 while the opening 7 of the exterior body 4 is sealed, the nozzle 9 is pulled out from the opening 7. Thereby, since the sealing property of the bag-like laminate film outer package 4 is secured by the pair of elastic bodies 41 and 42, the drop in the sealability of the bag-like laminate film outer package 4 at the time of drawing the nozzle 9 is suppressed.
- the outer peripheral nozzle portion 15 since only one nozzle sealed by the elastic members 35 and 36 is the outer peripheral side nozzle portion 15, a single liquid injection nozzle sealed by a pair of elastic members and a single vacuum The outer peripheral nozzle portion 15 can be easily pulled out as compared with the case where the nozzle is pulled out.
- the bag-like laminate film exterior body 4 formed by superposing two rectangular laminate films on each other and heat-welding three sides has been described as an example, but the bag-like film exterior used in the present invention
- the body may be configured such that one rectangular laminate film is folded in two, and two sides orthogonal to the folded side are thermally welded.
- leading-out the positive electrode tab 5 to the exterior from one edge 4a of the bag-like laminate film exterior body 4 and extracting the negative electrode tab 6 to the exterior from the edge 4b was demonstrated.
- the film-clad battery 1 in which both the positive electrode tab 5 and the negative electrode tab 6 are led out from one side can be applied to the present invention.
- the bag-like laminate film case 4 may be arranged.
