Abstract

PURPOSE:To increase charge-discharge capacity per weight and improve cycle performance by using an alloy of Al and Zn, or an alloy obtained by adding Sn, Si, and Ag to the Al-Zn alloy as negative active material. CONSTITUTION:In a secondary battery using nonaqueous electrolyte containing alkali metal ion, an alloy of Al and Zn, preferably whose weight ratio of Al to Zn is 85:15 - 35:65, is used as negative material. By using this negative material, charge-discharge capacity per weight is increased and generation of fine electrode is prevented even after charge-discharge is repeated, and steady performance is obtained. Use of an alloy obtained by adding at least one of Si, Sn, and Ag to the Al-Zn alloy still increases battery performance.

電池となることである。Conventional Structures and Problems Until now, non-aqueous electrolyte secondary batteries that use alkali metals such as lithium or sodium as negative electrodes have used various intercalation compounds such as titanium disulfide (TiS2) as positive electrode active materials. The development of batteries using an organic electrolyte in which lithium perchlorate or the like is dissolved in an organic solvent such as propylene carbonate has been actively pursued. A feature of this secondary battery is that by using lithium for the negative electrode, the battery voltage increases, resulting in a high energy density secondary battery.

機能を失わせるようなことも度々生じる。However, this type of secondary battery has not yet been put into practical use. The main reason for this is that the life span of 3 pages of charging and discharging is short, and the charging and discharging efficiency during charging and discharging is low. This is largely due to deterioration of the lithium negative electrode. That is, current lithium negative electrodes are mainly made by pressing a plate-shaped metallic lithium onto a screen-shaped current collector made of nickel, but the metallic lithium dissolves in the electrolyte as lithium ions during discharge. However, it is difficult to charge this and deposit it into the plate-like lithium that it was before discharging, and dendrite-like lithium is generated, which breaks off from the base and falls off, or in the form of small balls (moss). Phenomena such as the lithium deposited on the lithium ions being desorbed from the current collector occur. This results in a battery that cannot be charged or discharged. Furthermore, the generated dendrite-like metallic lithium often penetrates the separator that separates the positive and negative electrodes and comes into contact with the positive electrode, causing a short circuit and causing the battery to lose its function.

どである。Various attempts have been made to overcome these drawbacks of negative electrodes. Generally, methods have been reported in which the material of the negative electrode current collector is changed to improve its adhesion to the precipitated lithium, or an additive to prevent dendrite formation is added to the electrolyte. However, these methods are not always effective. In other words, as for the current collector material, it is effective for lithium that is deposited directly on the current collector material, but if the charging (precipitation) continues, lithium will be deposited on the precipitated lithium. The effect disappears. Furthermore, most additives are effective at the beginning of the charge/discharge cycle, but as the cycle progresses, they decompose due to K due to oxidation-reduction reactions within the battery and lose their effectiveness.

体の使用などを推奨している。Furthermore, it has been proposed to use an alloy with lithium as a negative electrode. A well-known example of this is lithium-aluminum alloy. In this case, a somewhat uniform alloy is formed, but this uniformity disappears when charging and discharging are repeated, and especially when the amount of lithium is increased, the electrode becomes atomized and collapses. It has also been proposed to use a solid solution of silver and an alkali metal (JP-A-56-7
386). In this case, it is said that there is no collapse like in alloy 61 base with aluminum, but the amount of lithium that alloys quickly enough is small, and metallic lithium may precipitate without being alloyed. To prevent this, the use of porous materials is recommended.

7-98978), a device using lithium-lead alloy (
JP-A-57-141869). However, in the case of a lithium-mercury alloy, the negative electrode turns into liquid particles of mercury due to discharge and does not maintain its electrode shape. Further, in the case of a lithium-lead alloy, the fineness of the powder due to charging and discharging of the electrode is greater than that of a scissors solid solution.

量当たりの充放電量は小さい。Recently, it has been proposed to use fusible metals such as tin and cadmium as negative electrode materials. By using this fusible alloy, stable charging and discharging can be performed without causing the negative electrode to become finely pulverized. However, in this fusible metal system, tin,
Since metals with large atomic weights such as cadmium, bis76 base, and lead are used, the amount of charge and discharge per unit weight is small.

オンとして放出させるものである。The feature is that an alloy to which at least one selected from the group of silver is added is used as the negative electrode material, and lithium is occluded in the form of a lithium-aluminum intermetallic compound in the alloy used as the negative electrode material by charging, and lithium is occluded in the electrolyte by discharging. It releases lithium ions as lithium ions.

There are many things that can be done to create an alloy of two materials and lithium.

えるようにして、充放電ができることは当然である。In addition, as for the range of charging and discharging, it is not necessary to discharge until lithium is completely removed from the negative electrode as in equation (1), but it is necessary to change the amount of lithium occluded in the negative electrode as in equation (2). It goes without saying that it can be charged and discharged.

+yeThe inventors have found that even when an aluminum-zinc alloy is used as a negative electrode material and charged and discharged in an electrolyte containing lithium ions, the electrode does not become finely powdered, and the amount of charge and discharge per unit weight of the negative electrode material also decreases. The big thing is the headline.

アルミニウム単体を負極材料とした場合には、充放電の
くり返しにより微細粉化し、電極形状は保てなくなる。When aluminum alone is used as a negative electrode material, repeated charging and discharging causes it to become finely powdered and the electrode shape cannot be maintained.

存在により充放電電気量が大きくなったと考えられる。On the other hand, when zinc alone is used as the negative electrode material, the shape of the electrode remains stable even after repeated charging and discharging, but the amount of electricity for charging and discharging is small. In other words, by using an aluminum-zinc alloy, even if charging and discharging are repeated, the presence of zinc prevents pulverization and the shape is stable, and the presence of aluminum increases the amount of electricity charged and discharged. .

られる。In other words, when the main active material for charging and discharging is aluminum, and in the case of an aluminum-zinc alloy to which silicon, tin, or silver is added, the amount of electricity charged and discharged becomes even larger. It is thought that the addition of these metals creates many phases in the K alloy, making it easier for the lithium occluded to diffuse along the phase interface.

The cycle characteristic is calculated by dividing the amount of electricity discharged in the 10th cycle by the amount of electricity discharged in the first cycle. It can be said that the larger the numerical values of the amount of charged electricity, the amount of discharged electricity, the efficiency, and the cycle characteristics per unit weight of the negative electrode material are, the better the negative electrode is.

Compared to conventionally used aluminum and fusible alloys, by using the aluminum-zinc alloy of the present invention, an alloy in which silicon, tin, and silver are further added to this alloy, as a negative electrode material, the charge/discharge rate per unit weight is improved. A secondary battery with a large amount of electricity and good cycle characteristics can be obtained.

Figure 2 shows the 10% change in weight per unit weight of the negative electrode material when the content of zinc in the aluminum-zinc alloy is changed.
This is a plot of the amount of electricity discharged during the cycle. Again, the test method is the same as in the previous example. From this, the alloy composition has an aluminum/zinc weight ratio of 85/15 to 3.
It can be seen that good negative electrode characteristics are exhibited when the ratio is 6/66.

However, when the weight ratio exceeds 66, the amount of aluminum decreases, and the amount of electricity charged and discharged decreases.
