Embodiment Construction

[0136] First, an unformed positive electrode plate is produced. Add water to a mixture of lead oxide, lead tetroxide, and short fibers (polyethylene terephthalate staple fibers, the same below) and knead, and then knead while adding dilute sulfuric acid in small portions. Thus, an active material paste for positive electrodes was manufactured. The active material paste was filled in an extensible current collector produced by stretching a rolled sheet made of a lead alloy, aged at 40°C and 95% humidity for 24 hours, and then dried An unformed positive electrode plate was produced.

[0137] Next, an unformed negative electrode plate was produced. Add to a mixture of lead oxide, short fibers, barium sulfate, carbon black as a carbonaceous conductive material, and bisphenol A-sulfanilic acid sodium salt-formaldehyde condensate as an organic compound that inhibits the coarsening of the negative electrode active material It kneaded with water, and then kneaded while adding dilute s...

Abstract

The invention provides a lead storage battery, which is a fluid type lead acid battery wherein charging is performed intermittently for a short duration each time, and high-rate discharging to a load is performed in a partial state of charge, said lead acid battery improving the charge acceptance and the life characteristic under PSOC relative to the prior art. A positive plate is used that has a positive active material total surface area per unit plate group volume set in a range of between 3.5 and 15.6 m 2 / cm <3>. A negative plate is used in which a carbonaceous conductive material and an organic compound that inhibits coarsening of a negative active material accompanied by charging / discharging are added to the negative active material. Moreover, compound(s) chosen from among cationic coagulant, cationic surfactant and phosphoric acid are added to an electrolyte, improving the charge acceptance and the life performance.

Description

[0001] The present invention is a divisional application of an invention application with an application number of 2012800514343 (international application number PCT / JP2012 / 74268), an application date of September 21, 2012, and an invention title of "lead storage battery". Technical field [0002] The present invention relates to a liquid lead storage battery having an electrolyte solution freed from an electrode plate group and a diaphragm in an electric tank. Background technique [0003] Lead-acid batteries are cheap and highly reliable, so they are widely used as power sources for starting automobiles, power sources for electric vehicles such as golf carts, and power sources for industrial equipment such as uninterruptible power supplies. [0004] In recent years, in order to prevent air pollution and global warming in automobiles, various measures to increase fuel consumption are being studied. As a vehicle that has implemented measures to increase fuel consumption, idling-sto...
