物質の密着を改善することを目的としたものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for manufacturing electrode plates for lead-acid batteries, and is particularly aimed at improving the adhesion between a grid and an active material.
従来の技術
従来より、鉛蓄電池用極板は、格子にペーストを充填し
た後、の熟成、化成という工程を経て製造される。BACKGROUND OF THE INVENTION Conventionally, electrode plates for lead-acid batteries are manufactured by filling a grid with paste, followed by aging and chemical formation.

招く。Problems to be Solved by the Invention In electrode plates for lead-acid batteries manufactured by conventional manufacturing methods, there is a problem in that the adhesion between the positive electrode active material and the grid is insufficient. If the adhesion between the anode active material and the lattice is insufficient, gas is likely to be generated, leading to poor utilization and a short lifespan.
問題点を解決するための手段

特徴とするものである。Means for Solving the Problems The present invention solves all of the above problems and improves the adhesion between the lattice and the active material. A current of opposite potential is passed inside,
This is characterized in that a normal chemical forming current is then applied to form a chemically formed electrode plate.
作用
本発明は上記の特徴を有することにより、格子と活物質

６１−２５９２４１号にあるように格子近傍に存在する
ｐｂｏ２ｔｉａ鉛→金属鉛とすることにより格子と活物
質の密着を良くすることも考えられる。This is because when the electrode plate after chemical formation is held in low specific gravity sulfuric acid or water, lead sulfur and Pb0x are present at the interface between the lattice and the active material.
This is thought to be due to the fact that a layer consisting of (1≦X≦1.7) is generated and this layer changes to 6 pb by flowing a reverse potential current to improve the density between the lattice and the active material. Furthermore, as described in Japanese Patent Application No. 61-259241, it is also possible to improve the adhesion between the lattice and the active material by changing pbo2tia lead present near the lattice to metal lead.

て犬なるものである。Effects of the Invention In the present invention, after complete chemical formation of the electrode plate, the anode is held in low specific gravity sulfuric acid or water, and then a current with a reverse potential is passed in the sulfuric acid, and then a normal chemical formation current is passed to obtain a preformed electrode plate. It becomes possible to improve the density of the lattice and the active material, and to provide a long-life lead-acid battery. In addition, in a sealed lead-acid battery with a cathode gas absorption type, if a large amount of oxygen is generated from the anode, heat is generated due to absorption at the cathode, which may cause thermal runaway, but according to the present invention, gas generation can be suppressed. It has great industrial value because it can reduce the possibility of thermal runaway.
