Abstract

PROBLEM TO BE SOLVED: To provide a lead-acid battery of superior high/rate discharge characteristic without changing manufacturing facilities. SOLUTION: Using an alloy of Pb-Ca, Pb-Sn or Pb-Ca-Sn, a lead powder is manufactured in a ball mill type or burton pot type manufacturing machine. This is used as a material lead powder for the electrode of a lead-acid battery. That is, powder is produced using an alloy mainly comprising three kinds of lead of Pb-0.1 wt.% Ca, Pb-1 wt.% Sn or Pb-0.1 wt.% Ca-1 wt.% Sn. The load alloy is charged into a ball mill to manufacture ordinary lead powder for producing powder mainly comprising lead monoxide, the three sorts of powder are kheaded by dilute solfuric and to form a paste to active material. This paste of active material is filled in a grating body of Pb-Ca-Sn alloy to be a positive electrode plate.

2. Description of the Related Art Lead storage batteries are widely used as power supplies for uninterruptible power supplies because of their low cost and high reliability. Recently, high-rate discharge characteristics have been strongly required to be improved as lead storage batteries used in these devices. As a means to improve high rate discharge characteristics,
It is important to improve the utilization rate of the positive electrode active material.
As a means for improving the utilization rate of the positive electrode active material,
JP-A-8-180876 and JP-A-9-289020 disclose a method of adding tin oxide, calcium sulfate, and the like to lead powder for the purpose of increasing the conductivity of the positive electrode plate and improving the diffusion of the electrolyte. Are disclosed. These methods add tin oxide or calcium sulfate powder to a paste active material that is a mixture of lead powder and dilute sulfuric acid,
It is produced by coating it on a grid made of a lead alloy.

However, the lead storage battery according to the above-described method has the following problems. That is, when tin oxide or calcium sulfate powder is added to the active material, an improvement in the utilization rate of the positive electrode active material is observed at a low rate discharge of about 0.3 CA. However, it has been clarified that in a high-rate discharge of about 3 CA, the effect of improving the utilization rate of the positive electrode active material is hardly recognized. Furthermore, since the specific gravity of the lead powder is greatly different from that of tin oxide or calcium sulfate, it takes a long time to mix the powder and the production cost increases.
