イクル寿命が短かい欠点がある。(b) Prior art While zinc as a negative electrode active material has the advantage of having a high energy density per unit weight and being inexpensive, zinc dissolves into the alkaline electrolyte during discharge and becomes zincate ions, and during charging, this zincate Since ions are deposited on the surface of the zinc electrode in a dendritic or spongy form, when charging and discharging are repeated, the deposited zinc penetrates the separator and reaches the counter electrode, causing an internal short circuit, resulting in a short cycle life.

られることがわかつた。 In order to improve this cycle life, it is being considered to incorporate various additives into the zinc electrode and electrolyte. Of these, Tokuko Sho is the most popular additive for zinc electrodes.
Publication No. 51-32365 is a noteworthy proposal. This proposal uses at least one of bismuth, cadmium, thallium, tin, selenium, tellurium, indium, lead, or oxides of these metals as an additive for the zinc electrode, and molds and sinters them together with the active material and fluororesin. That is what it means. However, only one type of each additive has been disclosed in the zinc electrode, and in order to obtain even better properties, various experiments were conducted to investigate the synergistic effects of combinations of various additives. As proposed in Publication No. 58-62633, thallium oxide or hydroxide, indium oxide or hydroxide, and metallic indium can be used as additives for zinc electrodes. The dissolution and dissipation of indium can be prevented by the presence of indium oxide or hydroxide, and these additives increase the hydrogen overvoltage of the zinc electrode and prevent the growth of zinc dendrites, and thallium alone can be added. In addition, the presence of metallic indium eliminates the drawbacks of thallium and indium oxides or hydroxides as poor conductors, resulting in better properties. I found out.

Publication No. 5185 proposes uniform electrodeposition of zinc by dissolving indate ions in an alkaline electrolyte. This method is particularly effective when indium is added to the zinc electrode, and can suppress uneven distribution of indium near the surface of the zinc electrode due to elution and prevent deterioration of the storage battery.

とにより電池容量も向上している。 Figure 2 shows the battery A of the present invention and the comparative battery B at 150 mA.
This is a discharge characteristic diagram when discharging with a current of It can be seen that the energy density per weight has been improved. This is because lithium ions in the electrolyte penetrate into the crystals of nickel hydroxide, which is the positive electrode active material, and further activate the nickel active material, thereby increasing the discharge voltage, which is lowered by the addition of indium to the zinc electrode. It is thought to be from That is, it seems that lithium restores the discharge voltage that was lowered due to indium added to improve cycle life. Furthermore, the battery capacity has also improved due to the activation of the nickel active material.

Measurements were made under cycle conditions in which the battery was discharged at 150 mA and the discharge was stopped when the battery voltage reached 1.2 V, and the initial capacity of battery B is shown as 100. As is clear from Figure 3, battery B, in which only lithium ions were added to the electrolyte, showed an improvement in capacity, but had a short cycle life, and battery C, in which only indium ions were added to the electrolyte, showed no improvement in battery capacity. I can't. On the other hand, the reason why the battery A of the present invention has a large battery capacity and a long cycle life is that the lithium ions added to the electrolyte are effective in improving the battery capacity.
It is thought that thallium and indium are highly effective in improving the cycle life, and furthermore, it is thought that the synergistic effect of the coexistence of indium ions and lithium ions further improves the charge/discharge cycle life.
