Problems solved by technology

[0007] Therefore, although various studies have been carried out on the performance and structure of the pole plate in the prior art, it has not been found that the high-rate discharge characteristics of the lead-acid battery can be improved by optimizing the structure of the pole plate, while ensuring other aspects of performance such as Soldering operability, internal short-circuit resistance, vibration resistance, and assembly operability of bus bars

Embodiment 1

[0050] (1) Manufacturing of positive plate

[0051] The raw material lead powder (a mixture of lead and lead oxide), water, and dilute sulfuric acid were kneaded in a weight ratio of about 100:12:14 to obtain a positive electrode paste as a positive electrode active material.

[0052] A 1.3 mm thick lead strip containing a Pb alloy containing about 0.07% by mass of Ca and about 1.3% by mass of Sn is repeatedly punched and unfolded using a reciprocating punching die through a cutting and drawing process, thereby forming a structure with a staggered structure of multiple grid lines Mesh of the grid. Then, the mesh sheet is shaped using a pair of rollers of a shaping mold to obtain a positive electrode plate drawn mesh grid as a positive electrode current collector. Then, the positive electrode paste is filled into the grid along the longitudinal direction of the grid on the expanded grid to form a lead plate. Then, the lead plate is cut into a positive electrode plate with a positi...

Embodiment 2～5

[0089] Except that the ratio a / W of the positive plate was 0.31 to 0.34, the plate group and the lead storage battery were prepared according to the same setup and process as in Example 1.

Embodiment 6～9

[0095] Except that the ratio b / W of the positive electrode plate was 0.14 to 0.205, the electrode plate group and the lead storage battery were prepared according to the same setup and process as in Example 3.

Abstract

The invention relates to a grid, pole plate and pole plate group used for a lead storage battery, and the lead storage battery. The ratio a / W of the distance a between the central position of a tab (2) in the grid (1) in the width direction and the edge (4) of a closer end of the grid (1) in the width direction to the width W of the grid (1) is 0.29-0.34; and the ratio b / W of the width b of the tab (2) to the width W of the grid (1) is 0.14-0.205. A positive pole plate and / or a negative pole plate of the pole plate group adopt / adopts the grid. The lead storage battery adopts the pole plate group. The lead storage battery is excellent in high-rate discharging properties and good in welding operability of a bus bar, inner short circuit resistance, vibration resistance and assembling operability.

Description

Technical field [0001] The present invention relates to a grid, an electrode plate, an electrode plate group, and a lead storage battery for a lead storage battery, and more specifically, to an electrode plate group having excellent high-rate discharge characteristics, excellent welding workability of a bus bar, and resistance to internal short-circuits, and using the same A lead-acid battery with excellent high-rate discharge characteristics of the plate group, and good soldering workability of the bus bar, resistance to internal short-circuit, vibration resistance, and assembly workability. Background technique [0002] Lead storage batteries (hereinafter sometimes referred to as “lead storage batteries” simply referred to as “batteries”) are widely used, for example, as starting and backup power sources for vehicles, as well as for electric vehicles, electric bicycles, electric motorcycles, electric scooters, and small electric vehicles. Power source for mopeds, golf carts, et...
