る。それに伴い、効率的でしかも合理的な製造法
が必要かつ重要な課題となつている。 Batteries that use light metals such as lithium as negative electrode active materials and non-aqueous electrolytes such as organic electrolytes have high energy density, and are being put into practical use in tandem with recent advances in electronics. Lithium-manganese dioxide batteries have come to be widely used as backup power supplies for electronic watches, calculators, cameras, various communication devices, and various memories. It is thought that the scope of its practical application will continue to expand in the future. Accordingly, efficient and rational manufacturing methods have become a necessary and important issue.
この種の電池の陰極に用いられるリチウム金属
は、非常に軟らかく、しかも粘りの高い、滑りに
くい材料であるため、電池の組み立てにおいて大
きな制約を受けており、生産性の高い製造法を確
立する場合の１つのネツクになつている。 The lithium metal used for the cathode of this type of battery is a very soft, sticky, and non-slip material, which poses major constraints in battery assembly, and it is difficult to establish a highly productive manufacturing method. It has become one of the networks.

は、巻回工程でリチウムが変形したり、力を加え
すぎると伸びすぎたり、あるいは変形によりセパ
レータよりはみ出したりして、内部短絡の原因に
なるなどの危検が大きい。 In particular, in cylindrical batteries with spiral electrode groups, winding a long lithium sheet in a spiral shape may cause the lithium to deform during the winding process, stretch too much if too much force is applied, or deform the separator. There is a great danger that the wire may protrude further and cause an internal short circuit.

る。このように電池組立てにおける信頼性を低い
ものとする欠点も有する。 In order to improve this point, there is a method of reinforcing the lithium by embedding a current collector made of a net made of nickel, stainless steel, or expanded metal in lithium. Furthermore, in order to prevent the lithium sheet from protruding from the separator due to bending due to deformation when the lithium sheet is wound, an attempt has been made to form the separator into a bag shape. The former method has an excellent lithium reinforcing effect, but the thickness of the lithium sheet becomes thicker than necessary as an active material, which has a negative effect on the high energy density that is a characteristic of lithium batteries. . Furthermore, the surrounding areas of the net and expanded metal are bent and become burrs, which break through the separator during winding and come into contact with the anode, causing an internal short circuit. As described above, it also has the disadvantage of lowering reliability in battery assembly.

らみ合い、うまく巻回できない不都合もある。 Furthermore, in the latter method, since the lithium sheet is wrapped in a bag-shaped separator, it is difficult to automate the separator bag processing process, which is a negative factor in terms of battery productivity. Furthermore, unlike ordinary metals, lithium has a very slippery surface, so when wrapped in a bag-shaped separator, it gets entangled with the separator within the separator during the winding process, making it difficult to wind it properly.
本発明は、以上のような従来の不都合を解消
し、信頼性および生産性の高い電池を与える陰極

た場合に最も効果を発揮する。 The present invention is most effective when applied to a battery having a spiral electrode group.
以下、本発明を実施例によつて詳細に説明す

らなるセパレータ４，４により構成されている。 FIG. 1 shows an assembly of a lithium cathode and a separator to form a spiral electrode group. This assembly 1 is composed of a lithium sheet 2, a nickel current collector 3 embedded in the end side of the lithium sheet 2, and separators 4, 4 made of a polypropylene nonwoven fabric crimped onto both surfaces of the lithium sheet 2.

溶着してもよい。 Figure 2 shows an outline of the process for manufacturing this assembly, in which a continuous long belt-shaped polypropylene nonwoven fabric sheet 4' is placed on top of which lithium sheets 3' cut into predetermined dimensions are placed at intervals. The lithium sheet and the polypropylene sheets 4', 4' are pressed and bonded together by supplying the other polypropylene nonwoven fabric sheet 4' and passing it between a pair of rolls 5, 5. It is. After this, if you cut the polypropylene sheet at the part that does not touch the lithium sheet, the first
The assembly shown in the figure is completed. Note that, as a matter of course, the width and length of the separator are larger than those of the lithium sheet. Separators that come into contact with each other at the peripheral edge of the assembly may be welded together, if necessary.

When using a polypropylene nonwoven fabric with a thickness of 0.20 mm as a lithium sheet, roll 5,
It is appropriate that the interval between the two nonwoven fabrics and the lithium sheet be about 0.05 mm narrower than the total thickness of the three layers of the two nonwoven fabrics and the lithium sheet.

したりすることによるトラブルが全くなくなる。 According to the above method, lithium is a soft metal, and polypropylene nonwoven fabric is porous and has a rough, fluffy surface. The nonwoven fabric becomes an integral assembly. the result,
There is no problem with the lithium sheet being displaced from the nonwoven fabric of the separator or protruding from the separator when the cathode assembly is wound.

がすぐれるのである。 The current collector 3 of the cathode is crimped onto the lithium sheet at the end of the winding when forming a spiral electrode group before being crimped onto the separator. The battery configuration is anode-limited, that is, if the capacity of the cathode is made slightly larger than that of the anode, a thin lithium sheet remains even at the end of discharge, and the current collector is at the end of the winding of the electrode group. Since only one side faces the anode and is located in a part where lithium is less consumed, it has an effective current collecting ability without disposing a current collector over most of the cathode as in the conventional case. In particular, since the lithium is crimped onto the separator, there is no local elongation or deformation during winding, and the reaction can be carried out almost uniformly over the entire area.Therefore, even at the end of discharge, the current collecting ability of the remaining lithium is quickly improved. It is possible.

The rotated electrode group 8 is inserted. This pole group is configured such that the cathode is located at the outermost periphery. 9 and 10 are ring-shaped insulating plates arranged above and below the electrode group 8; 11 is a sealing plate made of insulating resin with which the terminal member 12 is assembled; 13 is an anode terminal cap; and 14 is an anode connected to the terminal member 12. It is a current collector. Note that the cathode current collector is connected to the bottom of the case. The anode is made of carbon fluoride as an active material, a mixture containing a conductive material and a binder, which is integrally bonded to a titanium net current collector, and is covered with a separator.

In contrast to conventional models, the winding speed is limited to 15 pieces/minute.
It became possible to wind 40 pieces/minute.

ができた。 Furthermore, 1,000 each of battery A with the configuration shown in FIG. 3 using the cathode assembly according to the present invention and conventional battery B were tested in each of the three axes x, y, and z under conditions of a frequency of 55 Hz and a width of 3 mm. As a result of applying vibration to the batteries for 2 hours each, three batteries with an open circuit voltage of less than 3V were found to have an open circuit voltage of less than 3V.
There were 8 defective products in which the voltage decreased by 10 mV or more, but there were no such defects in battery A.
The cause of battery B's failure is thought to be an internal micro short circuit caused by burrs on the expanded metal used as the cathode reinforcement and current collector.In fact, in batteries with an open circuit voltage of less than 3V, burrs should be visually checked. I was able to do that.

が圧着されていればよい。 In the above embodiment, a method of applying pressure using a roller was shown as a method for integrating the lithium sheet and the separator, but other methods such as applying pressure using press pressure may be used. Furthermore, it is not necessary to integrate the entire surface of the lithium sheet with the separator as long as most of the lithium sheet is crimped.

とができる。 Although an example in which lithium is used as the cathode active material has been described, it goes without saying that the same can be applied to soft light metal cathode active materials such as alkali metals such as sodium. The separator is not limited to non-woven fabric, but may be one that partially bites into the cathode metal or has a rough surface into which the cathode metal bites.
以上のように、本発明によれば、電池の信頼性
