課題とされている。Conventional Structure and Problems A common problem with the above-mentioned zinc-alkaline batteries is corrosion of the negative electrode zinc by the electrolyte during storage. Conventionally,
It has been adopted as an industrial method to increase the hydrogen overvoltage by using frozen zinc powder, which is made by adding about 6 to 10% mercury to zinc, and to suppress corrosion to a level that causes no practical problems. However, in recent years, there has been an increasing social need to reduce the amount of mercury contained in batteries in order to reduce pollution, and various studies have been conducted. For example, lead, cadmium,
A method has been proposed in which alloy powder containing indium or the like is used to improve corrosion resistance and reduce the rate of icing. Although this is highly effective in suppressing corrosion, it has the opposite effect of deteriorating strong discharge performance by reducing the icing rate. In these proposals, the cause of the deterioration of strong discharge performance when the rate of discharge is lowered is unclear, but the discharge products cover the surface of active zinc, and the zinc hydroxide ions necessary for the discharge reaction are This is thought to be because the degree to which the supply to the surface is hindered is greater than when the mercury content is high, and the establishment of a low hydration rate zinc negative electrode that has both corrosion resistance and strong discharge performance is considered an important future issue.

明する。Although the effects of aluminum and magnesium mentioned above are clear in the examples described below, the mechanism of action is not fully understood. It is estimated that aluminum and magnesium, which are contained as an alloy in the negative electrode zinc and have a more base potential than zinc, are discharged together with zinc, and the discharge products promote the dissolution of the zinc discharge products into the electrolyte. Alternatively, the layer of undissolved discharge products densifies and plays a role in alleviating the effect of passivating the zinc surface, resulting in a state in which hydroxide ions are abundantly supplied to the active surface of zinc, causing zinc to be depleted. It is thought that the discharge utilization rate of zinc will increase as it continues to be secured in the trench where it is exhausted. In addition, when lead, cadmium, and tin are added as alloying elements, and when an element selected from the group consisting of gallium, thallium, silver, and indium is added to zinc as an alloying element, in either case, a frozen zinc alloy is produced. Although it is known from experience that it has an anticorrosive effect, there is no established theory regarding its mechanism of action. However, since the elements in the former group have a relatively small affinity for mercury, and the elements in the latter group have a relatively large affinity for mercury, it is thought that the mechanisms of action of the elements in each group are different. , the present invention improves corrosion resistance through the combined effect of these elements, and
Furthermore, by combining the effects of adding aluminum and magnesium, a low tonicity zinc negative electrode with excellent discharge performance and storage stability was realized. In other words, elements with a relatively low affinity for mercury are used to suppress the diffusion of mercury in the zinc alloy, which has frozen from the surface, from the surface layer into the interior through grain boundaries and to maintain a high mercury concentration on the surface. The presence of mercury at the grain boundaries is effective, and in addition, the mercury that has diffused into the grain boundaries is fixed at the grain boundaries and inhibited from diffusing into the grains. It is thought that it is effective for the dog element to exist at the grain boundaries. This allows a high concentration of mercury to be fixed on the surface and grain boundaries of the zinc alloy, where corrosion preferentially progresses, and increases the hydrogen overvoltage, making it possible to achieve effective corrosion protection with a small amount of mercury. It is estimated that As described above, the present invention has two elements: an additive element that improves the discharge performance, and an anti-corrosion effect on a ship that has a different mechanism of action.
The synergistic effect of adding different types of additive elements has resulted in a zinc negative electrode that has a low bushing rate, good corrosion resistance, and excellent discharge performance. Hereinafter, it will be explained in detail using examples.

Next, the above powder was put into a caustic potassium aqueous solution having a concentration of 10φ, and a predetermined amount of mercury was added dropwise while stirring to freeze it. Thereafter, it was washed with water, substituted with acetone, and dried to produce a frozen zinc alloy powder.

ある。As can be seen from this table, in all cases where the present invention was applied (I to Steps), the discharge performance was good and the battery expansion due to gas generation was small. On the other hand, among the conventional examples, when only a combination of anticorrosion elements were added (c-h), the expansion of the battery was small and gas generation was suppressed, but the duration of discharge under a heavy load of 510Q load is shorter than that of the product of the present invention. Furthermore, when only elements that smooth the discharge reaction of the negative electrode are added (a, b), the corrosion protection is insufficient and the battery expands significantly, and furthermore, self-depletion during storage and discharge reaction due to built-in hydrogen gas occur. Due to inhibition, the discharge performance after storage is also significantly degraded. As mentioned above, in the conventional method of a to F, 1
It is thought that a freezing rate of % is insufficient and it is necessary to further increase the freezing rate to make it practical. In the case of ixr, a highly practical zinc-alkaline battery with a low tension ratio of 1% or less and excellent storage stability and discharge performance has been obtained. The present invention complements the drawbacks of methods a and b and methods C to h,
This problem was solved very effectively due to their synergistic effect.
