Title:
POSITIVE ELECTRODE PLATE FOR LEAD ACID BATTERY, METHOD FOR PRODUCING SAID ELECTRODE PLATE, AND LEAD ACID BATTERY USING SAID POSITIVE ELECTRODE PLATE
Document Type and Number:
WIPO Patent Application WO/2013/122132
Kind Code:
A1
Abstract:
Provided are: a positive electrode plate for a lead acid battery, which contributes to the maintenance of a high capacity of a lead acid battery from the beginning and also contributes to the prolongation of the service life of a lead acid battery; and a lead acid battery using the positive electrode plate. A positive electrode plate produced by filling an active material in a grid body, wherein the active material has the following physical property value: the time required for the penetration of 100 ml of water through a block of the active material which has a thickness of 5 mm and a surface area of 25 mm2 is 1 to 10 minutes when water is allowed to pass through a layer of the charged active material from one surface side of the layer toward the other surface side of the layer at a pressure difference of 0.05 MPa. The positive electrode grid body is made from a lead alloy having a Ca content of 0.05 to 0.11 mass% and an Sn content of 1.1 to 1.8 mass%. Preferably, the positive electrode grid body is made from a lead alloy containing 0.005 to 0.05 mass% of Ag. More preferably, the positive electrode active material is prepared from a lead powder containing tetrabasic lead sulfate.
