Abstract

PURPOSE:To obtain a pole plate which does not generate self-discharge reaction and sustains quick use storing performance even after storing by filling the surface of a lead alloy substrate with an active substance consisting of PbO2 powder including the specified weight % of unformed substance consisting of PbO powder. CONSTITUTION:The surface of a lead alloy substrate is filled with an active substance consisting of the PbO2 powder including 20-30wt% of unformed substance consisting of PbO powder. For example, the surface of lattice type Pb-Ca system alloy substrate is filled with an active substance paste consisting of PbO powder and thereafter forming is carried out by charging the amount of electricity of 200% to the theoretical value with a current density of 1.0A/dm<2> so that unformed PbO remains by discharging. Next, after sufficient washing by water, a pole plate including unformed PbO of 24% can be obtained through drying process under about 100 deg.C. In case an active substance of unformed PbO is under 20%, the free sulfuric acid can not be seized by PbO and the quick use storing performance is lowered. Moreover, it exceeds 30%, amount of active substance of PbO2 is lowered and thereby capacity of quick use performance is lowered.

Description

【発明の詳細な説明】 本発明は即用式鉛蓄電池用極板の改良に関するものであ

面に生ずる不働態皮膜の生成するのを抑制して低温即用
性能（放電電圧）の低下を防止せんとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the electrode plate for a ready-to-use lead-acid battery, which prevents the formation of a passive film at the interface between the grid substrate and the active material during storage of the ready-to-use lead-acid battery. The aim is to prevent the deterioration of low-temperature immediate performance (discharge voltage) by suppressing this.

ものである。Generally, the anode plate of a ready-to-use lead-acid battery is made by filling a lattice-shaped substrate with a 4-st unformed active material made by kneading PBO with dilute sulfuric acid, chemically forming it into a PbO2 active material, and then washing it with water. It is obtained by removing the sulfuric acid content and drying it.

自己放電反応が進行しＰｂＳＯ４の不働態皮膜を生成し
て即用保存性能を低下せしめるものであった。However, since the electrode plate is porous, although the sulfuric acid content existing on the surface of the electrode plate can be removed by washing with water, the sulfuric acid content impregnated inside is difficult to remove and remains as it is. Therefore, if free sulfuric acid remains in the active material, a self-discharge reaction as shown in the formula below will proceed at the interface between the lead alloy lattice of the electrode plate and the active material, forming a passive film of PbSO4 for immediate storage. This resulted in a decrease in performance.

0... (1) As a result of extensive research in view of the current situation, the present invention has been developed for a ready-to-use lead-acid battery that can maintain excellent ready-to-use storage performance without causing a self-discharge reaction even when preserving the electrode plates. The anode plate was developed. That is, in the present invention, 20-30% of unformed active material made of PBO powder is applied to the surface of a lead alloy substrate.
It is characterized by being filled with an active material consisting of PbO2 powder containing a weight ratio of PbO2.

金格子とＰｂＯ２との界面における自己放電反応を抑制
するものである。In the present invention, unformed PBO powder remains inside the active material, and if such an electrode plate is stored,
First, the above-mentioned free sulfuric acid reacts with this PbO as shown in the following equation to consume the sulfuric acid and suppress the self-discharge reaction at the interface between the lead alloy lattice and PbO2 as shown in equation (1) above.

(2) Therefore, since the surface of the electrode plate is held by sufficiently active PbO2, it has excellent immediate storage performance without affecting the capacity of the electrode plate in any way.

リーの硫酸を捕捉することが出来ず即用保存性能が低下
する。又３０％を越えた場合にはＰｂＯ２の活物質量が
少くなるため即用性能の容量が低下するものである。The reason why the amount of unformed PBO active material is limited to 20 to 30 liters by weight in the present invention is that if it is less than 20%, free sulfuric acid cannot be captured by PbO, and the immediate storage performance deteriorates. If it exceeds 30%, the amount of PbO2 active material decreases, resulting in a decrease in the capacity for ready-to-use performance.

次に本発明の実施例について説明する。Next, examples of the present invention will be described.
