Problems solved by technology

However, according to experiments, in the method of this patent document 6, there is a problem that the positive electrode active material tends to become muddy, and there is a problem in cycle life.
In addition, the invention disclosed in Patent Document 6 is an invention for improving the discharge capacity of the battery. It is necessary to improve the charge acceptance capacity or improve the cycle under PSOC for ISS vehicles or valve-regulated lead-acid batteries for power generation control vehicles. In terms of characteristics, not much effect

Embodiment

[0105] In Japan, lead-acid batteries for automobiles are generally liquid-type, and there is no JIS standard (JIS D5301) for lead-acid batteries for engine starting with regard to valve-regulated lead-acid batteries. Therefore, in this embodiment, as an example, a 12V valve-regulated lead-acid battery was produced using a liquid-type battery case of B20 size specified by the JIS standard, but the present invention is not limited to the standard (structure) of the battery. . That is, no matter what kind of standard (structure) valve-regulated lead-acid battery is, by changing the existing positive and negative active materials and electrolyte specific gravity ranges to the present invention, the desired purpose of the present invention can be achieved.

[0106] Initially, an unformed positive plate is produced. Water is added to the mixture of lead oxide, trilead tetroxide and chopped fibers (polyethylene terephthalate short fibers, the same below) for kneading, and then a sma...

Abstract

Provided is a valve-regulated lead storage battery which is intermittently charged, each charge being conducted for a short period, and which in a partial state of charge (PSOC) is discharged at a high rate to apply a voltage to a load. The battery shows higher charge acceptance and has better life characteristics under PSOC than conventional valve-regulated lead storage batteries. Use is made of a positive electrode plate in which the active material has a specific surface area of 5.5 m2 / g or more. Use is made of a negative electrode plate in which the charge acceptance and life performance have been improved by adding a carbonaceous conductive material and a product of condensation of a bisphenol compound, aminobenzenesulfonic acid, and formaldehyde to a negative active material. The specific gravity of an electrolytic solution is set at 1.30-1.35. Thus, the valve-regulated lead storage battery is produced.

Description

technical field [0001] The invention relates to a valve-regulated lead-acid storage battery using paste-type positive and negative plates. Background technique [0002] Lead-acid batteries are roughly divided into liquid type and valve-regulated type. Due to their low price and high reliability, they are used as power sources for starting automobiles, power sources for electric vehicles such as golf carts, and uninterruptible power supply devices. It is widely used as a power supply for industrial machines. [0003] In recent years, in automobiles, various countermeasures against the increase in fuel costs have been proposed 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, ISS vehicles) that reduce the operating time of the engine, and micro-hybrid vehicles called power generation control vehicles that use the rotation of the engine for power wi...
