ということを考慮して、合金組成を決めている。Conventional technology In negative electrode absorption type lead-acid batteries, metal lead, which is the negative electrode active material, absorbs oxygen gas generated from the positive electrode during charging or self-discharging. This prevents an increase in battery internal pressure due to gas generation and reduces the amount of electrolyte. It has the function of suppressing In order to achieve this function, we selected alloys for the lattice body, electrode plate group joints, and pole columns that have a high hydrogen overvoltage and are difficult to generate oxygen when the battery is charged. The alloy composition was determined with consideration to the fact that self-discharge would not occur during the process.

になった。In this way, negative electrode absorption type lead-acid batteries have less loss of electrolyte during use, eliminating the need for troublesome water replenishment work and making it possible to seal the storage battery. Furthermore, by sealing the battery, no harmful gases are discharged outside the battery during use, making it easier to use the battery indoors.

ガスが充満した状態にある。Problems to be Solved by the Invention However, during use of conventional negative electrode absorption lead-acid batteries, especially in situations where they are constantly being charged, such as during standby use, the negative electrode pole, negative electrode grid body, negative electrode grid ear part, Alternatively, there has been a phenomenon in which rapid corrosion progresses at the joints of the negative electrode plate groups, causing some of the members to break. During use, a negative electrode absorption lead-acid battery is always filled with oxygen gas generated from the positive electrode.

Based on this assumption, various studies have been conducted, but no clear cause has been identified.

るために重要であることがわかった。A detailed analysis of a conventional negative-electrode absorption lead-acid battery in which corrosion of the negative electrode material progressed during standby use, leading to the material breaking, revealed that one area that had been corroded was not corroded. It was found that it contained a large amount of tellurium, which was not intentionally added. Furthermore, as the amount of antimony increases, the amount of corrosion increases at an accelerated pace, and controlling the amount of antimony, which was previously considered to be a small amount with no particular effect, is important in order to prevent corrosion of negative electrode members. I understand.

In the lead-acid battery comprising the above-mentioned member, the antimony content in the lead alloy forming the fR is 30 ppm or less. Alternatively, the above-mentioned drawbacks can be improved by constructing it from a lead alloy.
