Abstract

PURPOSE:To decrease the time required for recharging a battery after when the battery is left in an overdischarged condition, by selecting the proportion of a positive plate thickness to a negative plate thickness above a specific value. CONSTITUTION:When an enclosed lead storage battery is formed, the proportion of a positive plate thickness to a negative plate thickness is selectively arranged 2.2 or more. Accordingly, generation of lead oxide and basic sulfate lead by about 0.5V voltage appearing during an overdischarge is suppressed, and internal resistance of the battery can be prevented from increasing when the battery is left in the discharged condition, in consequence, a charging current is allowed to easily flow at charging after when the battery is left in an overdischarged condition, and the recharging time can be reduced.

ChargingConventional sealed lead-acid batteries had drawbacks such as difficulty in charging current (and long charging time) when charging after being left in a deeply discharged state (that is, left over-discharged).This is illustrated in Figure 1. 0, which appears during overdischarge as shown in
This is because lead oxide and basic lead sulfate produced at a voltage A of about 5V change during storage and increase the internal resistance of the battery. 2. The purpose of the present invention is to make the ratio of the anode plate thickness to the cathode plate thickness 22 or more, so that lead oxide, salt, etc.

きた。The discharge voltage behavior is shown when the ratio of the anode plate thickness to the cathode plate thickness is 22. Thus the voltage A as in the first
In a battery that exhibits a discharge voltage behavior with no discharge voltage, no increase in battery internal resistance is observed during storage, and as shown in FIG. 4, the battery almost reaches IA, which is the instantaneous cut current. For this reason, the electric time could be reduced to the level below X in FIG. 3, which is shown as an example of a conventional product.

時間を短縮できる等実用的価値甚大なるものである。As described above, the present invention has great practical value, such as being able to shorten the charging time after over-discharging.
