するようＫしてあった。FIG. 1 shows an example of a conventional cylindrical battery, in which a cylindrical anode can 1 contains a cathode mixture 2. The separator asi- and the anode mixture 4 are arranged coaxially with each other and loaded in good condition. By the way, in this type of battery, the seven pallets are formed into a cylindrical shape with both ends open. This is because when folding a piece of separator into a cylindrical shape, it is much simpler to use one with open ends at both ends than a book with a bottom. This is because it is easy to obtain accurate and uniform results. Then, the cylindrical seven separators a are inserted into the central bore s4a formed on the central axis of the lii polar mixture 4 in the assembly process, and then the lower end of the separator a is inserted as shown in FIG. Opening 3-
is sealed by closing with a layered lie formed of the injected and heat-fusible substance 6, and then the hollow part abP3 of the separator 8 is filled with the cathode mixture 11!2. By the way, the separator 8 is sometimes formed by winding rectangular separator pieces multiple times.In this case, conventionally, the separator pieces are glued in advance and wound to a predetermined diameter. It was marked so that it was formed into a cylindrical shape.

を維持することができる。That is, Fig. 3 M, B, C, and D show the main parts showing the method for manufacturing a cylindrical battery of the present invention. First, the separator 8 is made of seven separator pieces a cut into rectangular shapes as shown in Fig. 3. The dough is wound (preferably double-wound) into a cylindrical shape without gluing. At this time, the winding diameter of the separator 30 is made smaller than the 4 m diameter of the central lumen of the anode assembly 1fU4, which will be described later, so that the separator 3 can be easily inserted into the central lumen 4. It is. Then, as shown in Figure B, the above-mentioned seven wound pallets a are placed inside an anode can 1 (this example is an alkaline manganese battery, so the battery can becomes an anode can). It is inserted into the central lumen 4a of the anode mixture 4. By the way, in this state of bran, the separator element piece 8c itself does not have a strong restoring force that tends to expand, so a large barrier is formed between the separator 3 and the anode mixture 4. Next, as shown in the hollow part ab'KC of the separator 8, an expanding device 10 that contacts the inside of the hollow part 3b is inserted, and this expanding device 10 is used to unwind the seven parator pieces 3c that have been wound. Move or rotate in the direction. That is, in this embodiment, as the expanding device 10, a rod 11 is used which moves in a circle along the inner side of the hollow part 3b of the separator 3 in a direction opposite to the same direction of the seven parator pieces 8. . By moving the rod 11 in a circular direction in nine directions, the separator 8 is gradually expanded, and the separator 8 is finally brought into close contact with the central lumen 4 as shown in the final figure. be able to. Note that numeral 9 (not shown) represents the central lumen 4a.
The separator 8 that is in close contact with the separator 8 is maintained in the close contact state by injecting a heat-fusible substance or the like to close the lower end opening 3a and filling the hollow portion 8b with the cathode mixture, as described above. I can do it.

性能の安定化が達成できる。As described above, by bringing the separator 8 into close contact with the anode mixture 4 using the expanding device 10, the internal resistance of the battery can be significantly reduced, thereby improving and stabilizing the performance of the battery itself.

This elastic member 13 is formed of, for example, a brush-like flocked material, sponge rubber, or the like. Therefore, the elastic member 1a
When inserted into the hollow part sb of the separator 3 together with the rotary shaft 12, the elastic member 13 is compressively deformed and comes into contact with the entire inside of the hollow part 3b. By rotating the rotating shaft 12 in the opposite direction to the winding direction of the seven pallet pieces aC, the elastic member 18 also rotates in the same direction, and the upper slope pallet 3 is easily and reliably expanded. It can be brought into close contact with the inner side of the central lumen part 4.

図ることができるという優れた効果を奏する。As explained above, in the method for manufacturing a cylindrical battery of the present invention, seven rectangular parator pieces are wound without gluing to form a cylindrical separator, and this separator is placed inside a battery can. The central lumen of the anode mixture of nine cylinders loaded, 1
: Insert into part 1, and then insert an expanding device into the hollow portion of the seven parators to make contact with the inside of the hollow portion, and move or rotate the expanding device in the unwinding direction of the wound separator piece. As a result, the separator is expanded and brought into close contact with the central lumen of the anode mixture, thereby eliminating the need for gluing when forming the seven separators. Since it can be brought into close contact with the anode mixture, the internal resistance of the battery can be significantly reduced, which has the excellent effect of improving and stabilizing the performance of the battery.
