preparation example Construction

[0025] The plate preparation process is as follows:

[0026] (1) Put lead powder and short fibers in a mixer, add sulfuric acid and water and stir continuously to form lead paste 1 suitable for coating boards;

[0027] (2) Press the combined lead paste 1 on the grid 2 to coat the board;

[0028] (3) Curing and drying; making positive and negative plates.

[0029] (4) In the dilute sulfuric acid electrolyte, connect the positive plate to the positive electrode of the power supply, and connect the negative plate to the negative plate of the power supply, and use an electrochemical method to convert the lead paste 1 on the positive plate into PbO2-based Active material, lead paste 1 material on the negative electrode plate is transformed into active material mainly composed of spongy lead.

[0030] 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 concrete floor, and...

Abstract

The invention discloses a lead acid battery pole plate. The lead acid battery pole plate comprises grids and lead plaster. The lead plaster contains short fiber and is characterized in that the single fiber fineness of the short fiber is 0.15-0.8 D. By using the lead acid battery pole plate, the pole plate intensity is increased, waste loss during a production process is reduced, the mechanical strength of the active substance is increased, shedding can be prevented, and the cycle performance is increased; at the same time, generation of the floated powder is reduced, the positive plate porosity is increased, and primary capacity of a battery is increased.

Description

technical field [0001] The invention relates to the field of lead-acid battery components, in particular to a lead-acid battery pole plate. 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 preparing the pole ...
