The present invention does not assemble the battery assembly as before, without inserting a group of pole plates and separetta into the unit rolling, and inserting the pole plates and separetta directly into the unit roll to cover the cover, and then the plate itself protruding on the heavy cover. The present invention relates to an improved storage battery which forms poles protruding from the positive electrode plate and the negative electrode plate itself so that each cell can be directly connected to each other, and perforations are formed on the increase cover to check the sealing state of each unit rolling by air pressure.

Conventionally, as shown in the fourth diagram, the pole plate group 7 of the storage battery 1 is inserted into the longitudinal section and the cover 12 can be covered, and each unit roll 3 is primarily arranged on the pole column 14 by a plurality of pole plates. Welding the poles 14 to each other by pressing or spot welding the poles 14 through the grooves 15 of the rolling bulkhead 4 and the cover 12. By using epoxy adhesive, the weak adhesive force prevents each unit roll (3) from being completely enclosed, so that the electrolyte frequently leaks into other unit rolls (3), thereby reducing the electrical insulation effect. There was a drawback that the performance was degraded due to the significant drop, the self discharge was severe, especially the margin was large, the capacity was small, and the manufacturing process was complicated, which consumes a lot of material, work time and effort.

The present invention has been devised to solve such a conventional drawback and will be described in detail with reference to the accompanying drawings.

In the accompanying drawings, the same components as those in the fourth drawing are denoted by the same reference numerals and description thereof will be omitted.

1 is a battery roll formed by forming a projection 2 on an inner circumferential surface and forming a partition 4 horizontally between each unit roll 3, wherein the pole plate 5 and the separator are formed on the unit roll 3 of the battery roll 1 The plate group 7 consisting of (6) was inserted.

8 is a heavy cover inserted and sealed in the protrusion 2 of the battery cell roll 1, and the middle cover 8 has a terminal protrusion hole 9 formed on both sides thereof to protrude the terminal 10 of the pole plate 5 ( 10a) is to be inserted directly, and the through-hole 11 is formed in the center to check the sealing state between each unit rolling (3).

Reference numeral 12 denotes an upper cover of the battery precursor 1, and 13 denotes an adhesion plate which allows the pole plate group 7 to be in close contact with the unit precursor 3.

Referring to the effect of the present invention configured as described above are as follows.

That is, the pole plate group 7 composed of the pole plate 5 and the separator 6 is inserted into each unit roll 3 in the battery roll 1, and there is no fluctuation of the pole plate 5 by the close plate 13. The terminal 10 protruding to each terminal protruding rod 9 by pressing and sealing the vapor cover 8 by ultrasonic bonding to the protrusions 2 and the partition walls 4 in the battery precursor 1 and the partition wall 4 in close contact with each other without a short circuit between the electrode plates. 10a) should check the sealed state of each unit roll 3 soldered to each other. At this time, the sealed state of each unit roll 3 is confirmed by air pressure through the through hole 11 formed in the increase cover 8. The lead terminal may be pulled out of the upper cover 12 or the battery precursor 21 to cover the upper cover 12.

As described above, each unit roll 3 in the battery roll 1 is formed laterally, and the angular plate group 7 and the pole plate 5 are fixed to the fixing plate 13 for fixing, and are crimped with the thickening cover 8. By sealing, the margin of the battery is increased compared to the battery of the same size, so the capacity of the battery can be increased, and the unit cover (3) is completely sealed by ultrasonic bonding of the heavy cover (8), so there is no leakage of electrolyte. As the electrical resistance and voltage drop decrease, the electrical performance is improved and the contact plate 13 can be used to prevent damage to the short or pole plate group 7 due to the absence of movement of the plate group 7 even under severe vibration or shock. In addition, since the manufacturing process is simple and the material is saved, it is possible to mass-produce the system, and it is an economical and useful design that can supply a wide range of excellent performance batteries at a low price.
