Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] An embodiment of the present invention provides a positive lead paste for a lead-acid battery. The positive lead paste for a lead-acid battery is composed of the following components: 900-1000 kg of lead powder; 100-120 kg of dilute sulfuric acid; 100-110 kg of deionized water; -2kg; basic lead sulfate crystal powder 2-20kg.

[0028] Further, the concentration of sulfuric acid in the dilute sulfuric acid accounts for 50%.

[0029] In this preferred embodiment, the positive electrode paste of the lead-acid battery is composed...

Abstract

The invention relates to a lead acid battery positive lead paste. The paste consists of 900 - 1,000 kg of lead powder, 100 - 120 kg of dilute sulfuric acid, 100 - 110 kg of deionized water, 1 - 2 kg of polyacrylonitrile and 2 - 20 kg of basic lead sulfate crystal powder. A method for preparing a polar plate by adopting the lead acid battery positive lead paste is also provided. The problem of thecoarsening of lead paste granules caused by high temperature curing can be solved, and therefore, the cycle life of batteries can be effectively enhanced, and polar plate curing time can be shortened.

Description

technical field [0001] The invention relates to a positive lead paste of a lead-acid battery and a method for preparing a pole plate by using the lead paste, belonging to the technical field of lead-acid batteries. Background technique [0002] There are two mainstreams of plate curing processes in the field of lead-acid batteries: one is low-temperature curing at 40°C to 50°C, and the other is high-temperature curing at 70°C to 80°C. The battery plate adopts a low-temperature curing process, which is easy to form tribasic lead sulfate. The lead paste particles on the plate are small and densely distributed, and the bonding force of the lead paste on the plate is firm. However, due to low-temperature curing, it is easy to form β lead dioxide, and the battery capacity is high The lead paste is easy to soften, the battery electric cycle life is short, and the low temperature curing time is long, generally more than 48 hours; the battery plate is cured at high temperature, the ...
