Problems solved by technology

[0004] The traditional lead paste is mainly lead sulfate, lead oxide and free lead, which are converted into active substances after chemical conversion, that is, the positive lead paste is oxidized to produce lead dioxide, and the negative lead paste is reduced to produce lead. Due to the high resistance of lead dioxide, the charge The acceptance capacity is poor. Due to the influence of concentration polarization and other factors during discharge, the utilization rate of active materials is low. When the negative electrode paste is charged, lead sulfate undergoes a reduction reaction to produce spongy pure lead, and the volume of the negative plate shrinks nearly double. The greater the shrinkage, the smaller the pores and the lower the utilization rate of active substances

Abstract

The invention relates to the technical field of a lead storage battery, in particular to positive pole plate lead paste of a lead storage battery, a preparation method of the lead paste and the lead storage battery employing the positive pole plate lead paste. The positive pole plate lead paste comprises the following substances based on parts by weight: 1,000 parts of lead powder, 2-5 parts of colloidal graphite, 0.1-2 parts of antimony oxide, 1-15 parts of tetrabasic lead sulfate, 20-50 parts of lead tetroxide, 0.1-2 parts of fiber, 60-100 parts of dilute sulphuric acid, 60-100 parts of pure water and 2-15 parts of processing powder. With the positive pole plate lead paste of the lead storage battery, provided by the invention, the corrosion of the lead paste on grid alloy is reduced, and the binding force between the lead paste and the grid alloy is improved; and by the addition of graphite in a relatively large proportion, the conductivity of the battery is greatly improved, and the large-current charging receiving capability of the battery is good.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a lead-acid battery positive plate lead paste and a preparation method thereof, and a lead-acid battery using the positive plate lead paste. Background technique [0002] At present, lithium batteries, nickel metal hydride, fuel cells, lithium iron phosphate and lead batteries are used to provide power for electric mopeds. , cheap, recyclable and other characteristics, has gradually become the preferred power source. [0003] The main principle of rechargeable lead-acid batteries is: when discharging, the lead dioxide on the positive plate and the spongy lead on the negative plate react with the sulfuric acid in the electrolyte to form lead sulfate; Lead dioxide on the positive plate and spongy lead on the negative plate. As the active substances in the lead-acid battery that really participate in the battery reaction, that is, lead and lead dioxide are loose porous...
