PROBLEM TO BE SOLVED: To facilitate the insertion of an electrode body into a container, and to provide a battery having the super recycling characteristic by forming a projecting part in an inside surface of a bottom part of a battery container, and inserting this projecting part into a winding core part of a spiral electrode body, so as to form a battery in an organic electrolyte battery. SOLUTION: A separator is interposed between a sheet-like positive electrode and a sheet-like negative electrode, and they are wound around a pipe so as to form a spiral electrode body. On the other hand, a battery container 8 is formed by impact forming method, so that an inside surface of a bottom part is provided with a projecting part 9, which is formed into the same shape as the winding core part of the electrode body and that this projecting part 9 has a hollow part 10 communicating with an outside surface of a bottom part of the battery container. The projecting part 9 of this battery container 8 is inserted into a winding core of the electrode body, so as to form a battery. Consequently, positioning at the time of inserting the electrode body is facilitated, and the generation of damages on the surface of an electrode at the time of insertion is prevented, and the electrode body can be held securely, and a distance between the electrodes can be maintained constant. |
