Abstract

PURPOSE:To prevent the occurrence of overflowing at times of injection of dilute sulfuric acid and chemical conversion treatment of a battery jar as well as to make the extent of initial capacity improvable, by using red lead of more than the specified ratio as lead powder raw material, while performing the chemical conversion treatment of the battery jar with a positive plate filled with crude paste added with the dilute sulfuric acid inclusive of sulfuric acid in which more than the specified quantity of the red lead reacts at the time of kneading. CONSTITUTION:As lead powder raw material, red lead of more than 60mol% is used, while chemical conversion treatment of a battery jar takes place with a positive plate filled with crude paste added with dilute sulfuric acid inclusive of sulfuric acid in which more than 50% of red lead reacts at the time of kneading. If doing like this, since most of the lead powder materials are the red lead, a crystal of basic lead sulfate will not develop like ordinary paste, but this lead sulfate is much formed owing to abundant sulfuric acid, thus formation of the paste is solidified. Simultaneously lead dioxide to be much formed heightens the efficiency of chemical conversion treatment of a battery jar and, what is more, an excessive quantity of electricity is reducible.

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.
