集電体の改良に関するものである。Detailed Description of the Invention A) Industrial Application Field The present invention relates to alkaline zinc storage batteries, such as silver-zinc storage batteries and nickel-zinc storage batteries, which use a zinc electrode as a negative electrode and use an alkaline aqueous solution as an electrolyte. This invention relates to improvements in current collectors used in electrodes.

ルカリ電解液に溶出して亜鉛酸イオンとなり、充電時に
この亜鉛酸イオンが亜鉛極表面に電析すふという充放電
反応を行なう。(1) In conventional alkaline zinc storage batteries, zinc as a negative electrode active material has the advantages of high energy density per unit weight and low cost. However, zinc is eluted into the alkaline electrolyte during discharge and During charging, the zincate ions undergo a charging/discharging reaction in which they are deposited on the surface of the zinc electrode.
その結果、この亜鉛極の電析電位が水素発生電位より電
気化学的に卑なため、充電時や放置時に負極から水素が
発生し、電池内部圧力を高める欠点がある。As a result, since the electrodeposition potential of this zinc electrode is electrochemically less noble than the hydrogen generation potential, hydrogen is generated from the negative electrode during charging or when the battery is left unused, which has the disadvantage of increasing the internal pressure of the battery.

活物質を支持する集電体上からの水素発生を抑えること
はできない。Here, as a method of suppressing hydrogen generation from the active material, a method of adding a substance that increases hydrogen overvoltage, such as mercury or cadmium, to the zinc active material has been proposed. Although this considerably suppresses hydrogen generation from above the active material, hydrogen generation from above the current collector supporting the active material cannot be suppressed.
集電体面から水素が発生すると、電池内圧が上昇し、液
モレの原因となるばかりか、集電体と活物質が剥離し、
電池の容量低下を招く原因となる。When hydrogen is generated from the current collector surface, the internal pressure of the battery increases, which not only causes liquid leakage, but also causes the current collector and active material to separate.
This causes a decrease in battery capacity.

電体上からの水素発生が抑制される。As a countermeasure against this problem, for example, in Japanese Patent Application Laid-Open No. 13830/1983, in order to prevent self-discharge due to the use of a current collector with a low hydrogen overvoltage, cadmium, mercury, lead, tin, etc., which have a relatively high hydrogen overvoltage, are plated. A zinc electrode in which a zinc active material is coated on the current collector has been proposed, and this suppresses hydrogen generation from the current collector.

点があった。t/i Problems to be Solved by the Invention Although the effect of suppressing hydrogen generation from the current collector is recognized by plating metals with high hydrogen overvoltage on the current collector, these metals with high hydrogen overvoltage It has the property of easily forming a solid solution with zinc. Therefore, when zinc is electrodeposited on the current collector during charging, the plated metal forms a solid solution with the zinc, causing the plating to peel off, resulting in a problem in that the adhesion between the active material and the current collector decreases.

れる。2) Means for Solving the Problems The alkaline zinc storage battery of the present invention has a metal core plated with zinc, and a part of the plated zinc is used as a metal core having a nobler oxidation-reduction potential than zinc and a large hydrogen overvoltage. It is characterized by using a current collector partially substituted with metal ions for the zinc electrode. Here, since the oxidation-reduction potential is nobler than that of the zinc mentioned above, and the hydrogen (e)-plated zinc is pure zinc, self-discharge accompanied by hydrogen generation occurs when immersed in an alkaline aqueous solution, and the hydrogen overvoltage If part of the zinc is ion-replaced with a large metal, hydrogen generation from the plated zinc part can be completely suppressed.
また充電反応により、電着する亜鉛と一部をイオン置換
され九亜鉛メッキ部分との密着性は良く活物質と集電体
との剥離は生じない。In addition, due to the charging reaction, some of the electrodeposited zinc is ion-replaced, and the adhesion between the nine zinc plated parts is good and no peeling occurs between the active material and the current collector.
これらの理由により、長期充電放置を行なっても、特性
低下のない亜鉛極が得られる。For these reasons, a zinc electrode with no deterioration in characteristics can be obtained even after being left uncharged for a long period of time.

優れているという特徴がある。From the perspective of suppressing hydrogen generation from the current collector, the same effect can be obtained by applying eutectoid plating of zinc and a metal with a large hydrogen overvoltage, but if metals with a large hydrogen overvoltage, such as indium or The surface obtained by eutectoid plating of thallium and zinc is extremely smooth.
For this reason, there is a problem in that the adhesion between the active material and the 11-electrode body decreases. On the other hand, the surface of the current collector, which is ion-substituted with a metal having a large hydrogen overvoltage after galvanizing, is porous and has excellent mechanical adhesion between the active material and the current collector.

Zinc electrodes were prepared in the same manner as comparative zinc electrodes d, θ, f, and g.

同じてあった。Combining these zinc electrodes a-g with well-known sintered nickel electrodes, a cylindrical nickel 4-segment battery is formed, one for each condition.
I created 0 SEW each. and batteries A and B of the present invention, respectively.
%C1 comparison batteries were designated as E, F, and G. All of these batteries were then subjected to deep [100% charge/discharge cycles for one
After 0 cycles, the battery capacity was measured. The battery capacity at this time was almost the same for all batteries under all conditions.
更にこの後電池を満充電の状態にして４０℃の温度下に
１カ月間保存し、容量残存率と漏液のセル数を調べた。Further, the batteries were then fully charged and stored at a temperature of 40° C. for one month, and the remaining capacity and the number of leaking cells were examined.

放電による集電体からの水素発生量が多いために、内圧
が上昇し、漏液したものと考えられる。The remaining capacity of Batteries A, B, and 0 of the present invention is approximately 60%.
This value is mainly consistent with the value due to self-discharge of the nickel positive electrode. On the other hand, the remaining capacity rates of comparative batteries E, F, and G are smaller than this value, and it is understood that the self-discharge amount of the batteries is controlled by the zinc electrode. In addition, the batteries A and B of the present invention
No leakage was observed for %C, but for comparison battery D%
Regarding E%F, leakage was observed in 5 cells, 2 cells, and 5 cells, respectively. This is considered to be because the comparative batteries E and F produced a large amount of hydrogen from the current collector due to self-discharge, which caused the internal pressure to rise and cause leakage.

えられる。From the results in Table 2 in Table 2 below, it can be seen that the battery capacity of the batteries A, -, and C of the present invention is almost the same as the initial battery capacity, while the capacity of the comparative battery D-
It is observed that the capacity of G is lower than the initial value. This is thought to be due to the comparison zinc electrode d-G of the comparison battery G generating hydrogen from the surface of the current collector when left at high temperatures, which caused the current collector and active material to partially peel off. It will be done.
