もあった。However, in the conventional battery manufacturing method, when forming the power generating element, the positive and negative electrodes and the separator are simultaneously supplied from three different systems to the winding step and the laminating step. And the manufacturing apparatus becomes complicated. In addition, in the winding step and the laminating step, the positive electrode and the negative electrode supplied from the three systems are likely to be displaced from each other, so that the winding speed and the laminating speed cannot be increased so much that the productivity is reduced. There were also problems.

ればならないという問題も生じていた。In the conventional method of manufacturing a battery, the electrode and the separator are wound or laminated in a state of being simply overlapped, so that the electrode and the separator are partially floated without adhering to each other and the electrode and the separator are lifted. In order to prevent the distance from changing and the overlapping of these electrodes and separators, the power generating elements are wound or laminated and fastened once with tape, etc., and then stored in a robust battery container made of metal cans etc. This has not only made the operation of tape fixing and the like troublesome, but also caused a problem that a thick, heavy and expensive battery container had to be used.
