Embodiment

[0132] positive plate

[0133] Unformed positive plates were fabricated as follows. 0.1 mass % of short fibers (short fibers of polyethylene terephthalate, the same applies hereinafter) were added to 1.0 kg of raw lead powder mainly composed of lead oxide, and mixed with a kneader. Next, water and dilute sulfuric acid with a specific gravity of 1.26 (20°C) were added dropwise to the mixture of raw material lead powder and short fibers, and kneaded to prepare a paste-like positive electrode active material with a water content of 14% by mass and a lead sulfate content of 15% by mass. . A current collector composed of a lead-calcium alloy lattice was filled with the paste-like positive electrode active material at a rate of 67 kg per sheet, and aged for 18 hours in an atmosphere at a temperature of 50° C. and a humidity of 95%. Thereafter, the positive electrode active material filled in the current collector was dried at a temperature of 60° C. for 16 hours to fabricate a pos...

Abstract

Disclosed is a liquid-type lead storage battery which is charged intermittently and during short periods of time, and which in a partially charged state has high-rate discharge to a load. Charge acceptance and lifetime performance in a PSoC are improved by configuring an electrode plate group comprising: a positive plate in which the total surface area of the positive electrode active substance per unit volume of the electrode plate group is set within the range of 3.5-15.6 m2 / cm3; a negative plate with charge acceptance and lifetime performance improved by adding to the negative electrode active substance a carbonaceous conductive material and a bisphenol / aminobenzene sulfonic acid / formaldehyde condensate; and a separator in which the surface facing the negative plate is formed from a nonwoven fabric of a material selected from glass, pulp and polyolefin.

Description

technical field [0001] The invention relates to a liquid lead storage battery with electrolyte solution free from pole plate groups and separators in a battery cell. Background technique [0002] Lead storage batteries are inexpensive and highly reliable, and therefore are widely used as power sources for starting automobiles, power sources for electric vehicles such as golf carts, and especially as power sources for industrial equipment such as uninterruptible power supplies. [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 mileage per liter of fuel, research has been conducted on idling stop (hereinafter referred to as ISS car) by reducing the operating time of the engine and control of power generation by using engine rotation without waste cars such as micro-hybrid vehicles. [0004] In an ISS vehi...
