JPS6028174A - Lead storage battery with pole plate covered by film - Google Patents

Abstract

PURPOSE:To obtain a dry type lead storage battery which does not show corrosion of pole plate, freezing of water in the cold region and increase in weight by immersing an anode plate, a separation plate and a cathode plate into a mixed solution mainly composed of water, dilute sulfuric acid, salt and powder of volcanic ash. CONSTITUTION:A lead plate is respectively used for an anode plate 1 and cathode plate 2 and these are partitioned by an isolation plate 3. These anode plate 1, isolation plate 2 and cathode plate 2 are immersed into the solution mainly composed of water, dilute sulfuric acid, salt and powder of volcanic ash in order to produce a surface film 4. After the surface film 4 is formed, the solution is no longer necessary. The anode plate 1, isolation plate 3 and cathode plate 2 are attached to the battery case 5 and these are covered with the surface film 4 and the case is hermetically sealed. The portion which is usually filled with electrolyte is formed as empty space 6. Since the powder of volcanic ash in the surface film 4 has the structure of mesh consisting of string, the dilute sulfuric acid and water enter this mesh resulting in chemical combination and working as the electrolyte of existing storage battery.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dry type lead-acid battery that does not require an electrolytic solution made of dilute sulfuric acid.

Traditionally used lead-acid batteries use dilute sulfuric acid as the electrolyte, which causes various problems such as corrosion of the drawing board, zero concentration control of the I2 solution, freezing of water in cold regions, and an increase in the weight of the storage battery. was there.

The present invention was made to eliminate this drawback, and to explain this with drawings, as shown in Figure @1, an anode plate (1),
A lead plate is used as the cathode plate (2), and a separator plate (3) is used to partition between the cathode plates. The anode plate (1), the separator plate (3), and the cathode plate (2) are immersed in a solution mainly composed of water, dilute sulfuric acid, salt, and volcanic ash powder to form a lead surface coating (4). It is a storage battery. After the surface wave WA(4) is generated, the liquid is not necessary. Therefore, an anode plate (1), a separator plate (3), and a cathode plate (2) are attached to the electric housing (5), and these are coated with a surface coating (
4) and has a sealed structure. Conventionally, the part where the electrolyte is located is a space (6). The misfire q is based on the principle η' is a storage battery purchased with a positive plate (1), a separator plate (3), a cathode plate (2), and a surface wave Tri (4), so this is necessary as a sail position. It is possible to construct a storage battery with a certain voltage.

The principle of this storage battery is explained in 31.1 below. Table j(
When the structure of the volcanic ash powder in (4) is observed with an electron microscope, it has a filamentous network-type J#J structure.

@Sulfuric acid and water enter this network and are chemically bonded.
It functions in a manner similar to that of the electrolyte in conventional S batteries. The surface coating (4) remains dry because the electrolyte does not simply enter the mesh but is chemically bonded.

Since this type of lead-acid battery is used, there is no corrosion of the electrode plates, there is no need to once manage the electrolyte, there is no freezing of water in cold regions, and the battery is lightweight. Furthermore, ′α so (5
) can also be omitted if necessary. It is a revolutionary invention because it exhibits the above-mentioned effects.
