本発明は格子体に活物質を支持させた極板を有する水溶
液系の蓄電池に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an aqueous storage battery having electrode plates in which an active material is supported on a lattice.
（従来技術とその問題点）
一般に、水溶液系の蓄電池は電槽内に、格子体に各々の
活物質を支持させた陽・陰極板を交互に配置してなる。(Prior Art and its Problems) Generally, an aqueous storage battery is constructed by alternately arranging positive and negative electrode plates in which each active material is supported by a lattice in a battery case.

によりエキスバンド格子（特開昭５７−１５８９５７号
公報参照）とすることにより形成される。For example, in the case of a lead-acid battery, the lattice body of the anode and cathode plates is made by casting lead or a lead alloy, punching a lead alloy plate, or
It is formed by inserting a large number of grooves into a lead alloy plate and pulling both ends to form an expanded lattice (see Japanese Patent Laid-Open No. 57-158957).

のが要求される。By the way, the capacity of a storage battery is determined by the amount of active material x utilization rate and the amount of electrolyte x utilization rate. Therefore, in order to increase the capacity of a storage battery, the lattice must support more active material, increase the spaces between the particles that make up the active material, and make the particles themselves finer, in other words, soften the active material. It is useful to increase the utilization rate of the active material and electrolyte by widening the area of the active material in contact with the electrolyte (in a fluidized state). In order to support more active material, it is necessary to increase the active material supporting capacity of the lattice.This can be easily achieved by increasing the lattice density of the lattice, but this increases the weight of the lattice. Therefore, since the storage battery using the above-mentioned lattice body has a limit in weight and volume per unit capacity, it cannot be expected to increase the capacity to a large extent.Under these circumstances, Japanese Patent Application Laid-Open No. 57-210569 discloses a technique in which the grid of the electrode plate is made of synthetic resin and coated with a conductive metal to reduce the weight. A conductive metal coating is applied to a resin lattice body] There is a problem in that the manufacturing process is complicated, such as the need to perform surface treatment on the resin lattice. Since the thickness of the coating must be increased, the weight increases, and sophisticated technology is required to adjust the coating thickness.

The purpose of the present invention is to provide a storage battery that is lighter overall and has increased capacity.

A current collector 9b projects from the upper end 9a of the grid body 9, and holes 9d are formed at a predetermined interval from the upper end 93 and the lower end 9C.
... are drilled respectively. The lattice density and cross-sectional area of the extended lattice of the metal lattice body 9 are determined only from the capacity of the storage battery, that is, the current collection characteristics, and therefore the metal lattice body 9 does not need to support the active material. The lattice density is lower than that of the lattice body 10, and the cross-sectional area of the lattices constituting the lattice can also be made smaller. The lower end 10a of the resin grid 10 is provided with a foot 10b that rides on the saddle 8a of the bottom plate 8, and the lower end 10a and the upper end 10c are provided with holes 9d of the metal grid 9... The convex portion 10d that is fitted into the
...is installed protrudingly. The lattice density and cross-sectional area of the resin lattice body 10 are determined solely by supporting the softened anode active material containing fine particles of peracid (PbO2). Therefore, the resin lattice 1o does not need to take into account current collecting properties and can have a higher lattice density than the metal lattice 9 since it supports the active material.

池の重量を軽量化出来る。Therefore, since the lattice body was constructed by combining a metal lattice body and a resin lattice body, the lattice density of a metal lattice body with a high specific gravity can be made low by considering only the current collection property. The resin lattice with a low lattice density has a high lattice density according to the properties of the active material with only support for the active material in mind, so the lattice's ability to support the active material can be increased without increasing the weight. Therefore, more of the softened active material can be reliably held in the lattice, improving the utilization rate and increasing the capacity of the storage battery. In addition, metal lattice bodies with high specific gravity only need to be considered for current collection characteristics, so the lattice density can be lowered, making them lighter, while resin lattice bodies with low specific gravity support a large amount of softened active material. Even if the lattice density is increased in order to increase the utilization rate of the active material, the specific gravity is low, so the lattice body does not become heavy, so the lattice body becomes lightweight, and the storage battery can be made lighter accordingly. Furthermore, since the resin lattice body and all ff1iJ lattice bodies are arranged in a staggered manner, the lattice density is higher, and even if the active material is made softer, the active material can be supported by the lattice body, which increases the utilization rate. This makes it possible to obtain a storage battery with a large capacity and high efficiency. In addition, when the capacity of the storage battery is kept constant, the amount of active material can be reduced as the capacity increases, and the grid body can also be made smaller, so the weight of the storage battery can be reduced accordingly.
