必要がある。BACKGROUND OF THE INVENTION Conventional Technologies and Their Problems Sealed tO storage batteries that utilize oxygen cycle reactions have been increasing in recent years as portable devices have become popular, and demands for improved energy tightness and cost reduction are increasing. In order to improve the volumetric energy density, it is effective to place the electrode plates in every empty space in the container, but due to gas generation from the electrode plates when pouring dilute VT and when forming the electric tfff. The problem with the electrolyte is that it tends to overflow. ! It was in the manufacturing process. Note that the current efficiency in forming a battery is good for the negative electrode plate, but is low for the positive electrode plate due to the side reaction of oxygen gas generation, and usually 200% or more of the theoretical value is passed through the current. To account for the loss of water at this time, it is necessary to inject a large amount of dilute sulfuric acid in advance.

問題点を解決したものである。Means for Solving the Problem The present invention uses 60 mol% or more of red lead as a raw material for lead powder, and also adds dilute ta-acid containing sulfuric acid, which reacts with more than 50% of the red lead during crosstalk. By forming a battery using a positive electrode plate filled with fresh paste, and in particular by controlling the amount of electricity in the tank to be 150% or less of the theoretical value for the positive electrode plate, a porous lobarator is tightly compressed to the electrode plate. This solves the problems of lead-acid batteries.

できる。Function: Because most of the lead powder raw material is red lead, crystals of basic ffl-acid lead do not develop like in normal pastes, but a large amount of lead sulfate is generated due to the abundance of sulfuric acid, which strengthens the structure of the paste. Make it. At the same time, a large amount of lead dioxide is generated, which increases the efficiency of battery cell formation and reduces the amount of excess electrical layer.

。EXAMPLE A sealed lead-acid battery without a flowing electrolyte was prototyped and tested using a lead-calcium-tin alloy as a grid and a porous plate made of glass IaH with an average diameter of 1.0 μm or less as a separator. Here, the material of the lead powder raw material and the amount of dilute sulfuric acid used for mixing the raw paste were varied. The results are shown in Table 1. Note that the paste filling chamber and liquid injection (2) of the prototype batteries were all the same, and the chemically formed electrical layer was set to 150% of the theoretical value.

反り量が50%以上のときに優れている。Yandenyong-eup is excellent when the raw material lead powder contains 60% or more of red lead and the amount of warping with dilute sulfuric acid is 50% or more.
