を招（）があった。Conventional technology Conventionally, methods have been adopted in which the electrode plates for lead-acid batteries are changed, the current is constant, or the current is reduced after waiting for the start of hydrogen generation (the completion of charging of the negative electrode) - the problem that the invention seeks to solve However, in the case of HB batteries, if the current is constant until the end of formation, or if the formation is carried out using a current flow method that reduces the current, the Sb eluted from the positive electrode lattice remains deposited on the negative electrode plate. As a result, the battery after electrolyte injection has the disadvantage of reducing the hydrogen overvoltage of the negative electrode plate (increased self-discharge, increased frequency of water replenishment, etc.).
本発明は上記欠点を除去することを目的とするものであ

ものである。Means for Solving the Problem The present invention provides a negative electrode potential of 10.4V vs Cd at the final stage of chemical formation.
This is characterized by suppressing Sb precipitation on the negative electrode plate by applying a large current that is more base than /cd''.

Ｊｔが少ない）という傾向が認められた。After constructing a battery consisting of one working alloy lattice and anodizing the Pb-Sb alloy lattice, holding the Pb-α alloy lattice (negative electrode) at a constant potential and scanning from that potential in the anode direction, An oxidation current based on the dissolution of Sb species is observed at 0.7 to 0.8V vs Cd/cd"°. Therefore, as a result of holding the negative electrode at various potentials and measuring the above oxidation current, the first
As shown in the figure, -O,4V vs Cd/cd”
When held at a more base potential, the oxidation current is small (precipitated S
There was a tendency for the Jt to be low).
この原因として、Ｓｂの還元（Ｓｂ−４ＳｂＨυ、多量
の水素発生による析出Ｓｂの脱落などが考えられる。Possible causes of this include reduction of Sb (Sb-4SbHυ) and shedding of precipitated Sb due to generation of a large amount of hydrogen.
