Problems solved by technology

[0008] But no matter shuttle loom or shuttleless loom in the above-mentioned prior art, it is all single-weft weaving method (as the fineness of warp and weft is the same, or the warp fineness is the same, the weft fineness is the same), thus the The lead mesh grid has the following defects: lead wires are used for the latitude and longitude lines, and the lead consumption is large; the grid has no frame, and the expansion of the active material cannot be restricted during the charging and discharging process of the battery, and it is prone to contact short circuit of the positive and negative active materials and softening of the positive active material Falling off reduces the service life of the battery; the grid has no lugs, and requires prefabricated busbars, which are then welded with weft lead wires to form tabs. The process is complex and inefficient
[0009] In summary, the current preparation methods of lead grids have obvious defects and need to be further improved.

Embodiment 1

[0052] Such as image 3 Shown, a kind of lead-acid storage battery uses the lead mesh grid, comprises the grid body that is woven by the warp thread and the weft thread, has included in the grid body a plurality of independent grids adjacent to the left and right and up and down (that is, used for lead The grid of the size required by an independent piece of pole plate in the acid battery is an independent grid); the lead grid coating area formed by the grid body is at the boundary of its adjacent independent grid division, along its Thick plastic wires or thick lead wires are arranged in the parallel direction to form a frame (located at the boundary position of each independent grid) extending along the parallel direction of each independent grid. This embodiment can adopt thick plastic wire wefts 2 as forming The weft line of the frame; the lead mesh coating area formed by the grid body is provided with thick plastic wires, or thick lead acid, or several fine plastic wire s...

Embodiment 2

[0062] as attached Figure 4 Shown:

[0063] 1. The positive grid fabric is composed of:

[0064] Fabric composition in the weft direction (left and right): each independent grid contains a total of 6 conductive thick lead wire wefts 1, and the core wire of the lead wire is glass fiber, which is coated with 0.8SnPb alloy by extrusion to form a diameter coaxial with the core wire 1.2mm composite lead wire; a PP plastic weft 3 with a diameter of 0.8mm is woven between two adjacent thick lead wire wefts 1, and each independent grid contains 7 fine plastic wefts 3; each grid contains a diameter There are two 1.5mm thick plastic wefts 2 in total. The thick plastic wefts form the left and right frames of the grid to limit the vertical expansion of the lead plaster and the thick lead wire wefts 1. The material is PP.

[0065] Fabric composition in warp direction (upper and lower): each independent grid contains 5 thin plastic warp threads (thin PP plastic warp threads) with a diame...

Embodiment 3

[0070] as attached Figure 4 Shown:

[0071] 1. The positive grid fabric is composed of:

[0072]Fabric composition in the weft direction (left and right): each grid contains 6 conductive thick lead wire wefts 1, the core wire of the thick lead wire weft is glass fiber, and the 1.2SnPb alloy is coated by extrusion to form a coaxial wire with the core wire. Composite lead wire with a diameter of 1.2mm; a thick plastic weft thread (ABS plastic weft thread) 3 with a diameter of 0.8mm is woven between two adjacent thick lead wire weft threads 1, and each grid contains a total of 7 fine plastic weft threads 3; The grid contains two thick plastic wefts 2 with a diameter of 1.5 mm. The thick plastic wefts form the left and right borders of the grid to limit the expansion of the lead paste and the thick lead wire wefts 1 in the vertical direction. The material is ABS.

[0073] Fabric composition in warp direction (upper and lower): each grid contains 5 thin plastic warps (thin PP pl...

Abstract

The invention discloses a lead mesh grid for a lead storage battery and a preparation method of the lead mesh grid. The lead mesh grid is characterized by comprising a grid body formed by weaving warps and wefts, wherein the grid body at least comprises one independent grid; a lead mesh coating area formed by the grid body is arranged at the boundary of the independent grid, and thick plastic wires or thick lead wires are arranged in the weft direction of the grid body so as to form two side frames extending in the weft direction of the independent grid; and a lead mesh coating area formed bythe grid body is arranged at the boundary of the independent grid, and thick plastic wires or thick lead wires or a plurality of thin plastic wire twisted edges or hot melting wire twisted edges are arranged in the warp direction of the grid body so as to form two side frames extending in the warp direction of the independent grid. The lead mesh grid has the advantages that the use amount of leadis small, the grid is provided with the side frames, expansion of active substances can be limited in the charging and discharging process of the battery, positive and negative active substance contact short circuit and positive active substance softening and falling are not likely to happen, the service life of the battery is prolonged, and the grid is provided with tabs and does not need prefabricated busbars.

Description

【Technical field】 [0001] The invention relates to the field of lead accumulators, in particular to a lead mesh grid for lead accumulators with high production efficiency and good corrosion resistance and a preparation method thereof. 【Background technique】 [0002] Because of its stable and reliable, no memory effect, low price, and can be made into a single large-capacity battery, lead-acid batteries are widely used as car starting power, uninterruptible power supply, power supply and energy storage from electric bicycles to diesel submarines In the field of power supply and other fields, its output and storage power still rank first in chemical power supply. There are three preparation methods for the grid of traditional lead-acid batteries: ① Gravity casting, which has a wide range of applications, but low efficiency and high pollution; ② Perforated grid, this method is to prefabricate the lead strip first, and then punch the hole. Its advantages are High efficiency, but...
