部と短絡し早期に容量が低下する原因となっている。Conventional structure and its problems This type of sealed lead-acid battery uses a sealed method in which all the oxygen gas generated during charging is absorbed by the negative electrode plate. Calcium alloys or lead-calcium-tin alloys are used. 7 This type of lead-calcium alloy has less surface corrosion due to overcharging than conventional lead-antimony alloys, but local corrosion is large and the inside of the lattice of the positive electrode plate is corroded. -C has the disadvantage that the expansion of the corrosion products increases the elongation of the electrode plate. Therefore, due to corrosion of the positive electrode plate due to overcharging, the upper part of the positive electrode plate stretches and short-circuits with the current collecting portion of the negative electrode plate, causing an early decrease in capacity.
