Embodiment

[0114] Add water to the mixture of lead oxide, red lead (trilead tetroxide) and short fiber (polyethylene terephthalate short fiber, the same below) and knead, then add a small amount of dilute sulfuric acid several times While kneading, the positive electrode active material paste was produced. The active material paste was filled in an expanded current collector produced by stretching a rolled sheet made of lead alloy, aged at 40°C and a humidity of 95% for 24 hours, and then dried to produce an unformed positive electrode plate. .

[0115] Next, an unformed negative electrode plate was fabricated. Water is added to a mixture of lead oxide, short fibers, barium sulfate, carbonaceous conductive material, and an organic compound that has an effect of suppressing the coarsening of the negative electrode active material, and kneading is performed, and then, dilute sulfuric acid is added in small amounts and kneaded. Refining to make active material paste for negative electrode...

Abstract

The disclosed liquid lead storage battery, which is charged intermittently for short periods at a time and which performs high-rate discharge to a load while in a partially charged state, has increased operating-life characteristics and charge acceptance by means of using: a cathode plate wherein the specific surface area of active material is at least 6 m2 / g; an anode plate wherein a carbonaceous conductive material and a bisphenol / aminobenzenesulfonic acid / formaldehyde condensate are added to an anode active material, increasing charge acceptance and operating-life performance; and a separator of which the surface that faces the anode plate is formed from a nonwoven fabric of a material selected from glass, pulp, and a polyolefin.

Description

technical field [0001] The invention relates to a liquid lead storage battery with electrolyte solution freed from pole plate groups and separators in the cell. Background technique [0002] Lead storage batteries are characterized by low cost and high reliability, so they are used as a power source for starting automobiles or as a power source for electric vehicles such as golf carts, especially as uninterruptible power supply devices, etc. The power supply of the machine is widely used. [0003] In recent years, in order to prevent air pollution and global warming in automobiles, various measures to increase the mileage per liter of fuel have been studied. As a car that implements measures to increase the number of kilometers traveled per liter of fuel, an idling stop (Idling stop, hereinafter referred to as an ISS car) and a control system that reduces the operating time of the engine by stopping the engine when stopping walking without unnecessary idling have been studi...
