Embodiment

[0059] First, an unformed positive plate is prepared. Add water and knead in the mixture of lead oxide, lead red and chopped fiber (polyethylene terephthalate short fiber, the same below), and then add a small amount of dilute sulfuric acid while kneading to prepare the positive electrode With active substance paste. The active material paste is filled into a rolled sheet made of a lead alloy, such as figure 2 In the extended current collector 21 shown. The extended current collector 21 is composed of a grid portion 22 , an upper frame 23 , a lower frame 24 , and ear portions 25 . After filling the active material paste, it was aged for 24 hours in an atmosphere of 40° C. and a humidity of 95%, and then dried to obtain an unformed positive electrode plate.

[0060] Here, regarding the utilization rate related to the discharge reaction, positive electrode plates having various positive electrode active materials were produced as follows. That is, when the addition of dilut...

Abstract

In a fluid-type lead battery in which discharging to a load is carried out in a partially charged state, since the battery does not become fully charged in a PSOC, stratification of the electrolyte is minimized, thereby improving life performance, even if agitation of the electrolyte is made difficult by gas production. On each negative plate (1), a non-woven fabric (2) composed of fibers of at least one material selected from a group of materials comprising glass, pulp and polyolefins comes into contact with the entire surface of the plate without being integrated with the plate. Each negative plate (1), which is in contact with the non-woven fabric (2), is contained in a bag-like separator (3) comprising a microporous synthetic resin sheet, and is laminated with a positive plate (4). The non-woven fabric undergoes a sheet-making process in which glass fibers, pulp and silica powder are preferably used as the main components.

Description

technical field [0001] The present invention relates to a liquid lead-acid storage battery having an electrode plate group and an electrolytic solution freed from a separator in a battery case. Background technique [0002] In recent years, with regard to automobiles, various countermeasures for increasing fuel costs have been studied in order to prevent air pollution and prevent global warming. As vehicles for which measures to increase fuel consumption have been implemented, idling-stop vehicles (hereinafter referred to as ISS vehicles) that reduce the operating time of the engine, and micro-hybrid vehicles, so-called power generation control vehicles, that use the rotation of the engine for power without waste, have been studied. [0003] In ISS vehicles, the number of times the engine is started increases, and the lead-acid battery is repeatedly discharged with a large current. Also, in the ISS vehicle or the power generation control vehicle, since the amount of power g...
