従来の技術
密閉式アルカリ蓄電池は過充電特電池内で発生するガス
を電池内で吸収する構成を採用している。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to improving the discharging performance of sealed alkaline storage batteries. [Conventional technology] Sealed alkaline storage batteries do not allow gas generated in overcharged cells to be discharged into the battery. The system uses a structure that absorbs water.
すなわち、正極容量に対し、負極容量を過剰に設け、過
充電時に正極で発生する酸素ガスを、負極活物質に環元
させる方法である。That is, this is a method in which the negative electrode capacity is provided in excess of the positive electrode capacity, and oxygen gas generated at the positive electrode during overcharging is converted into a negative electrode active material.
しかし急速充電を行なった場合、充電電流が増加するた
めに、それに対応して、充電完了後正極よシ発生する酸

素ガスをより多く正極より負極へ透過させ、電池内圧の
上昇を抑制していた。However, when rapid charging is performed, the charging current increases, and the amount of oxygen gas generated from the positive electrode increases accordingly after charging is completed, resulting in an increase in battery internal pressure, which impairs battery characteristics. Sometimes. Conventionally, as a countermeasure to this problem, the amount of electrolyte was regulated and the number of pores in the separator and electrolyte layer was increased to allow more oxygen gas to permeate from the positive electrode to the negative electrode, thereby suppressing the increase in battery internal pressure.
発明が解決しようとする課題
しかし、こうした従来の方法、すなわち電解液量を規制
して急速充電性能を改善する方法では電極中の電解液が
不足して、放電時の電極反応が円滑に進行せず、放電電
圧が低下する問題があった。Problems to be Solved by the Invention However, with these conventional methods, that is, methods of improving rapid charging performance by regulating the amount of electrolyte, there is a shortage of electrolyte in the electrode, making it difficult for the electrode reaction to proceed smoothly during discharge. First, there was a problem that the discharge voltage decreased.
課題を解決するための手段

前記の細孔を設けることにより、多孔体内部およびその
表面に電解液が侵入し、保持される。このため電解液量

で補なわれることにより充放電特性の劣化が抑制される
。Effect: By providing the above-mentioned pores, the electrolyte enters the inside of the porous body and its surface and is retained therein. Therefore, even if the amount of electrolyte is increased by a corresponding amount, rapid charging as before is possible and the discharge characteristics are excellent over a long period of time. In other words, the increased gold electrolyte is retained only on the surface of the porous substrate of the electrode,
Deterioration of charge and discharge characteristics is suppressed by supplementing the electrolyte solution on the surface of the porous substrate to compensate for the shortage of electrolyte in the electrode due to expansion of the electrode as the charge/discharge cycle progresses.

合金蒸着法でも効果がある。(Left below) From the above results, we found that 1/2 of aluminum was added to the negative electrode substrate.
0~415 MaOl % o~1/40v when added
The internal pressure of the battery was lower than that of the battery with 0.1% added, and the valve did not operate. In addition, when aluminum was not added and the electrolyte was reduced from 2.2 to 2.0, no valve operation occurred, but a decrease in discharge voltage was observed. In the case where aluminum is added to the base in this way, the aluminum dissolves into the electrolyte after the battery is assembled, forming a liquid-retaining portion consisting of pores, in which the electrolyte is retained. Therefore, the amount of liquid retained in the separator did not increase, and pores were formed in the separator to facilitate the passage of the gaff, thereby preventing valve operation. In addition, when 9/10'IO 1% aluminum was added, the discharge voltage was low and a disassembly investigation was conducted to find that the negative electrode substrate had collapsed. This is because the addition amount was too large and the base strength decreased. As mentioned above, the addition of aluminum is 1
/2o~415ma OE% is preferable. Although this example shows an example in which aluminum is added to the negative electrode nickel base of a nickel-metal hydride storage battery, other battery systems such as nickel-cadmium batteries may also be used, and the addition is not limited to the negative electrode but can also be applied to the positive electrode base. The additives are not limited to aluminum, but other alkali metals, alkaline earth metals, and their salts also have good effects. Further, in this embodiment, aluminum is blended into the substrate by vacuum evaporation and heat treatment, but vacuum evaporation alone or other methods such as ion sputtering or nickel-aluminum alloy evaporation are also effective.
