Description of the Related Art Conventionally, a so-called lead powder containing a mixture of PbO and metallic lead as a main component has been used as a raw material for producing a paste-type lead battery electrode plate. Usually, the degree of oxidation of the lead powder, that is, the ratio of PbO contained in the lead powder, is 60 to 80%. Such lead powder is kneaded with dilute sulfuric acid to form a paste, filled in a lattice, then aged and then chemically converted to produce an electrode plate. In the case of an anode plate, the metallic lead in the paste is gradually oxidized in a kneading and aging step before the chemical conversion step, and immediately before the chemical conversion step, 5% or less, more preferably 1% or less.
It is necessary to reduce the content to below. This is because if a large amount of metallic lead remains on the electrode plate before chemical formation, a sufficient amount of PbO 2 is not generated in the chemical conversion step, resulting in poor electrode plate performance.

Lead powder having a thickness of 0 μm and an oxide layer of 20% or more was produced. This was subjected to classification and oxidation treatment to produce four kinds of lead powders shown in Table 1. Using this lead powder, a positive electrode paste was prepared by a conventional method, filled in a grid for a lead battery for an automobile, and immediately dried at 150 ° C. for 30 minutes to obtain a positive electrode plate. Using this electrode plate, a battery having a nominal capacity of 27 Ah (5 HR) was assembled and formed into a battery case. For comparison with a conventional product, a battery using a positive electrode plate which had been filled with each paste and aged for 24 hours in an atmosphere of 50 ° C. and a relative humidity of 98% was prepared and subjected to a comparative test.
The test results are shown in Table 2. Battery No. 5 to 8 at 50 ℃ / 98%
All of the batteries aged for 1 day had a PbO 2 content of 86-90% and a 5 hR capacity of 27.0 Ah or more. The PbO 2 amount and the 5 hR capacity after the formation were at the same level, but the PbO 2 amount and the 5 hR capacity after the formation were at low levels in the batteries Nos. 1 and 2. This indicates that the use of lead powder with a particle size of 0.1 to 10 μm and an oxide layer thickness of 60% or more can provide the same performance as that of the conventional ripened product by drying in a short time.
