preparation example Construction

[0024] The plate preparation process is as follows:

[0025] (1) Put lead powder and short fibers in a mixer, add sulfuric acid and water to form a lead paste suitable for coating boards through continuous stirring;

[0026] (2) Press the combined lead paste on the grid to coat the board;

[0027] (3) curing and drying; making positive and negative plates.

[0028] (4) In the electrolyte of dilute sulfuric acid, the positive plate is connected to the positive electrode of the power supply, the negative plate is connected to the negative plate of the power supply, and the lead paste substance on the positive plate is converted into PbO2-based activity by electrochemical methods. Substances, lead paste substances on the negative plate are transformed into active substances mainly composed of spongy lead.

[0029] Drop test: Take the polar plates of each embodiment and comparative example respectively, number them, and weigh them. Make the polar plate parallel to the clean con...

Embodiment 6

[0063] Example 6: Choose 10 negative electrode raw plates, number them randomly, choose 0.35D for their single fineness, 2-3mm in length, and add 0.15% of the total mass of the lead paste. The result is as follows:

[0064]

[0065] Comparative example of this embodiment: choose 10 negative electrode raw plates, number them randomly, choose 1.5D for single fineness, 2-3mm in length, and add 0.15% of the total mass of the lead paste. The result is as follows:

[0066]

[0067] The index of embodiment 6 is obviously better than comparative example.

Embodiment 7

[0068] Embodiment 7: 5 pieces of negative electrode cooked plates are optional, randomly numbered, the single fiber fineness is selected as 0.35D, the length is 2-3mm, and the addition ratio is 0.2% of the total mass of the lead paste. The result is as follows:

Abstract

The invention discloses a short fiber used for lead-acid storage battery plates. The short fiber comprises a plurality of organic fibers with a length of 6mm or shorter, and the single fiber fineness ranges from 0.15 to 0.8D. The short fiber is capable of increasing plate strength, reducing loss in production process, increasing active substance mechanical strength, preventing shedding, improving cycling performance, reducing generation of floating powder, increasing positive plate porosity, and increasing initial capacity.

Description

technical field [0001] The invention relates to the field of lead-acid battery additives, in particular to short fibers for lead-acid battery pole plates. Background technique [0002] Since the invention of lead-acid batteries, they have always had an absolute advantage in chemical power sources. This is because of its low price, easy access to raw materials, sufficient reliability in use, suitable for large current discharge and wide ambient temperature range. Lead-acid batteries are currently the most widely used secondary energy in the world, with the highest safety performance and highest recyclability. At the same time, after years of development of lead-acid battery technology, breakthroughs have been made in its specific energy, cycle life, and high and low temperature adaptability. As an important part of the battery plate, short fibers play a pivotal role in the battery. . [0003] Short fibers with a general length of 1-4 mm are added to the lead paste for prep...
