常な腐食による切損現象を防止して高信頼化を達

The purpose is

食が発生することがあつた。 In lead-acid batteries that have been used for many years, abnormal lump-like corrosion, so-called local corrosion, occurs in the sealing area between the positive electrode column and the battery lid, and in the case of the negative electrode, conductive parts near the electrolyte surface, such as the electrode plate lugs, develop. Cathodic corrosion resulting in porosity sometimes occurred.

〜30μｍである。 The phenomenon and cause of this corrosion differ between the positive electrode and the negative electrode. In the case of the positive electrode, lead reacts with a small amount of electrolyte that has creeped due to capillary action, becoming neutral or alkaline and accelerating corrosion, whereas in the negative electrode, the antimony-rich conductor made of a lead-antimony alloy reacts with lead. Stibine (SbH 3 ) is generated from the eutectic portion, and antimony (Sb) is removed, resulting in a porous structure. Conductors such as poles and grids are generally manufactured by casting, but during the solidification process of the molten metal, a dendrite structure is formed due to the precipitation of primary crystals, and a eutectic part fills the gaps between them, and the dimensions of the primary crystals are Normal thickness 10
~30 μm.

での腐食が著しく進行しかえつて破断しやすい。 When this dendrite structure is subjected to solution treatment, the antimony in the eutectic portion is dissolved and dispersed in the primary crystal and disappears. However, in this case, as with pure lead, corrosion at the grain boundaries progresses significantly and it is easy to break.

出したことに基づくものである。 The present invention cools at least the ear member near the surface of the electrolyte in the positive electrode column or the negative electrode while applying ultrasonic vibration to a molten metal made of a lead-antimony alloy.
It is characterized by being produced by solidification, and when the molten metal is solidified while applying ultrasonic vibration, the individual primary crystals of the dendrite structure and the crystal grains that are aggregates thereof are refined, and this manufacturing method is When applied to parts that include areas where abnormal corrosion occurs on the conductive parts of the positive electrode or negative electrode, especially on the positive pole on the positive electrode side and on the ear parts near the electrolyte surface on the negative electrode side, the abnormal corrosion seen in the past can be effectively removed. This is based on the discovery that the

The support body, 6 is an ultrasonic vibration transmitter, and 7 is connected to the ultrasonic oscillator through a horn. For lead parts, molten lead-antimony alloy is poured from the pouring port 4 to fill a predetermined space 2 in the molds 1 and 1', and cooled and solidified while applying ultrasonic vibrations by the vibration transmitter 6. . When the molten metal is solidified while applying ultrasonic vibrations in this manner, a lead alloy having a fine crystal structure is obtained. Once solidified, the ultrasonic oscillation is stopped and the lead parts are removed from the mold and cut above the gate.

る。 Since the lead-acid battery of the present invention uses a lead component having a fine crystal structure that is solidified while applying ultrasonic vibration as the positive electrode column, the progress of corrosion at the sealing part with the battery lid is suppressed. There is no accident of disconnection of the positive electrode conductor due to abnormal local corrosion. The above example uses a lead part with a refined crystal structure as a positive electrode column, but if a lead part manufactured in the same way is welded to a negative electrode plate to form a lug, abnormal corrosion in this part Porous formation can also be prevented.
