Abstract

PURPOSE:To obtain a plate for a sealed lead storage battery having an improved gas-absorbing efficiency by adding an amount of lead sulfate within a specified range to prepare a negative active material. CONSTITUTION:A sealed lead storage battery is assembled by using a negative plate made by using a negative active material containing 5-20wt% of lead sulfate. In such a battery, since the recovery of the negative plate after electric discharge is later than that of a positive plate, there is no possibility of the generation of hydrogen gas. Besides, the existence of the above specified amount of lead sulfate in the negative active material does not cause any changes to the capacity of the battery and the utilization of the active material. Therefore, according to this method, the gas-absorbing efficiency of the sealed lead storage battery is improved.

Description

向上を図らんとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sealed lead-acid battery, and aims to improve gas absorption efficiency.

えられている。In recent years, the demand for so-called maintenance-free products has increased,
A cage-type sealed lead-acid battery has been developed in which dilute sulfuric acid is impregnated into matte glass fibers and has the characteristics of no leakage and no need for water replenishment. In this sealed lead-acid battery, oxygen gas generated at the anode plate is reduced to water at the three-phase interface between the lead on the cathode plate and the electrolyte, as shown in the following equation.

はや水素ガスは発生せず電池は密閉化されることになる
。2Pb10, +2H* SO4→2P b3Q, +2
When an HtO battery is overcharged, the oxygen generated from the anode plate is absorbed by the cathode plate, and the resulting lead sulfate (PBSO*) is reduced at the cathode plate.It gets hot, so hydrogen gas is no longer generated. The battery will be sealed.

柄を避けるには常に陽極板の回復性か速やければよい。However, in this type of battery, during recovery charging after discharge, the anode and cathode become fully charged at the same time, and it cannot be said that the gas absorption reaction occurs quickly in the overcharged region, and if the cathode plate recovers more quickly, the hydrogen Gas generation was observed. To avoid such problems, it is always best to improve the recoverability of the anode plate.

。In a sealed lead-acid battery, its capacity is controlled by the amount of electrolyte, and even considering the utilization rate of the anode active material and cathode active material, it is necessary to add 5 to 20 wt% lead sulfate to the cathode active material. Even if it is included, there is no change in the Ws cell capacity or active material utilization rate. However, in the cathode active material, 20 wt%
29 wt % or less of lead sulfate in the cathode active material is suitable because the reverse ionic absorption performance deteriorates if the amount exceeds 29 wt % of lead sulfate.

In a sealed lead-acid battery characterized by containing Qwt% of lead sulfate, hydrogen gas is not generated because the cathode plate recovers more slowly after discharge than the anode plate.
