〈産業上の利用分野〉
この発明は、リチウムを負極活物質とする非水電解液二
次電池に用いる負極の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for manufacturing a negative electrode used in a non-aqueous electrolyte secondary battery using lithium as a negative electrode active material.
〈従来の技術〉
リチウムを負極活物質とする非水電解液二次電池では、
二硫化チタンＴｔＳ２や三酸化モリブデンＭ ＯＯ３に
代表される層状＠造を有する化合物を正極活物質とし、
また一般に、多孔性の集電体を負極と負極端子板内底面

配した＠造が採られている。<Conventional technology> In non-aqueous electrolyte secondary batteries that use lithium as the negative electrode active material,
A compound having a layered structure represented by titanium disulfide TtS2 and molybdenum trioxide MOO3 is used as a positive electrode active material,
Generally, a @ structure is adopted in which a porous current collector is disposed between the negative electrode and the inner bottom surface of the negative electrode terminal plate, or between the positive electrode and the inner bottom surface of the positive electrode can.
この種の電池では、放電により負極から非水電解゛液中

充放電不能になったり、またこの樹枝状の電析リチウム
が生長してセパレータを貫通し正極に達して内部短絡を
起こすことから、充放電サイクルに伴う性能低下が大き
く、実用上十分な電池寿命が１ｑられないという不都合
がある。In this type of battery, lithium ions, which are generated by elution from the negative electrode into the non-aqueous electrolyte during discharge, do not precipitate in the initial shape during charging but are deposited in a dendritic form on the negative electrode surface, and these fall off, making charging and discharging impossible. In addition, this dendritic electrodeposited lithium grows, penetrates the separator, reaches the positive electrode, and causes an internal short circuit, resulting in a significant drop in performance during charge/discharge cycles, and the battery life is shortened to 1q, which is sufficient for practical use. There is an inconvenience that there is no such thing.
上記の樹枝状のリチウムの析出を可及的に抑制して電池

場合について述べれば、充電時にはリチウムが負極の基
体となるアルミニウムと合金を形成するように電析する
ようになり、これによってリチウムの樹枝状生長が抑制
ないし阻止される。In order to suppress the above-mentioned dendritic lithium precipitation as much as possible and improve battery life, lithium can be easily alloyed with this.
It has been proposed to alloy it with one or more metals and use it for a negative electrode. Examples of this are lithium-aluminum alloy negative electrodes and lithium-magnesium alloy negative electrodes.In the case of lithium-aluminum alloy negative electrodes, during charging, lithium forms an alloy with aluminum, which is the base of the negative electrode. The dendritic growth of lithium is thereby suppressed or prevented.
このようなリチウム合金からなる負極を形成する方法と

の後にリチウムを電着して合金化する方法などが知られ
ている。Conventionally, methods for forming a negative electrode made of such a lithium alloy include a method in which this type of lithium alloy powder is pressure-formed into an electrode shape and filled into the negative electrode terminal plate, or a method in which aluminum is pre-filled in the negative electrode terminal plate. Known methods include crimping or spot welding foil or aluminum plates, and then electrodepositing lithium to form an alloy.
ところが、上記のリチウム合金粉末を用いる方法では、
負極の機械的強度が不足して充放電中に脱落しあるいは
容易に崩壊し易い、活物質充填密度が低いといった欠点
がある。またリチウムを電着して合金化する方法の場合
、製造に際して長時間の充電工程を要するので作業性が
悪く、製造工程の煩雑化は免れない。However, in the above method using lithium alloy powder,
The disadvantages include that the negative electrode lacks mechanical strength and easily falls off or collapses during charging and discharging, and that the active material packing density is low. Furthermore, in the case of a method in which lithium is electrodeposited and alloyed, a long charging process is required during production, resulting in poor workability and complication of the production process.

できた。Therefore, the present applicant has developed a lithium alloy negative electrode by stacking, for example, a lithium plate and an aluminum plate one after another inside the negative electrode can, and alloying them by thermocompression bonding (hot pressing) within the negative electrode can. A method for manufacturing this was proposed in Japanese Patent Application No. 60-220898. In addition, when using a porous negative electrode current collector in this method, this negative electrode current collector is fixed in advance to the inner bottom surface of the negative electrode can by spot welding, etc., and lithium plates and aluminum plates are sequentially stacked on top of it. It is constructed by heat-compression bonding. According to this method, it was possible to produce a negative electrode with excellent mechanical strength and shape retention during charging and discharging through a fairly simple process.

作業性の低下を招く等の問題がある。<Problems to be Solved by the Invention> However, in the above manufacturing method, the lithium plate and the aluminum plate were handled individually and used by stacking them in the negative electrode can. There is still a problem that the number of steps is large, the complexity of the work cannot be sufficiently resolved, and mass productivity cannot be sufficiently increased. Also,
When stacking a lithium plate and an aluminum plate in a negative electrode can, misalignment is likely to occur due to eccentricity, and as a result of this misalignment, lithium remains unalloyed at the periphery of the negative electrode. It is not possible to prevent dendritic electrodeposition of lithium, which leads to deterioration of battery performance, and the remaining lithium adheres to the thermocompression mold, resulting in a decrease in workability.

負極を形成することを要旨とする。Means for Solving the Problems> The method for manufacturing a non-aqueous electrolyte battery of the present invention is to stack a lithium sheet and a metal sheet that can be alloyed with lithium and then press them together into one piece with a predetermined size. The gist is to obtain a stack, place this stack on the inner bottom surface of a negative electrode terminal plate, and then alloy it by thermocompression bonding to form a negative electrode made of a lithium alloy layer on the inner bottom surface of the negative electrode terminal plate.

Aluminum sheet 1, lithium sheet 2, and aluminum sheet 3 of 1 mm and 0.2 mm are pressed in a sandwich shape using a pressure roller 7 at 500 KMCf to obtain a stacked sheet 8, and then this stacked sheet 8 is punched and cured. The stacked body 14, which has been pounded into a disk shape by the tools 9 and 10, is made into a cup-shaped negative electrode terminal plate 12 with a stainless steel net 13 spot-welded as a current collector on the inner bottom surface of the stacked body 14. It was placed on the inner bottom surface. Thereafter, this negative electrode terminal plate 12 is placed on the hot plate 18 as shown in FIG. 1(B) with the stacked body 14 placed on the inner bottom surface thereof.
In addition, the pressure plate 19 is located on the upper part of the stack 14,
C. and 1.5 ton/cf for 5 minutes, and the aluminum layer 15, lithium layer 16, and so-called aluminum 17 constituting the stack 14 were alloyed by thermocompression bonding to form a lithium-aluminum alloy layer. and,
Using this lithium-aluminum alloy layer as a negative electrode, a 2016 type lithium secondary battery was produced in the following manner.

The negative electrode terminal plate 13 to which the above lithium-aluminum alloy negative electrode 20 is fixed is stacked on the upper surface of this positive electrode mixture via a separator 21 made of polypropylene nonwoven fabric, and further the positive electrode can periphery and the negative electrode terminal plate periphery are stacked. A polypropylene annular gasket 25 was placed between them, and the opening of the positive electrode can was crimped.

Also, when stacking metal sheets that are easy to alloy on both sides of a lithium sheet, for example, stack an aluminum sheet on the top surface of the lithium sheet and a magnesium sheet on the bottom surface, and use the same method as above to stack the lithium-aluminum sheet. Of course, a Mu-magnesium alloy negative electrode may be made. Further, in the embodiment, these sheets are crimped after being stacked, but they may be handled as one body immediately after being stacked without being crimped.
