AI Technical Summary

Problems solved by technology

Because the lead in the lead-acid battery pollutes the environment, the negative electrode lead and sulfuric acid will react slowly to form self-discharge, resulting in short storage time, large power loss, and the positive electrode is easy to fall off, and the number of cycle discharges is small
Lithium batteries are rare resources because lithium resources are less in nature, so the cost is high
Nickel-hydrogen, nickel-cadmium, and iron-nickel batteries are also unfavorable in the promotion of large-capacity batteries due to the high cost of nickel

Embodiment Construction

[0006] The present invention will be further described below according to the embodiments.

[0007] Cathode material lead dioxide (PbO 2 ) is filled in the grid of lead-antimony alloy, zinc (Zn) is used as negative electrode after surface deoxidation treatment, the middle of positive and negative electrodes is filled with glass wool or other alkali-resistant fibers, and potassium hydroxide (KOH) solution is mixed with 50%- Prepared at a concentration of 70%, filled with fibrous filling.

[0008] Lead dioxide and zinc are substances in the discharge state, and the following reactions occur during the discharge process:

[0009] positive electrode:

[0010] negative electrode:

[0011] At this time, the positive pole loses electrons, and the negative pole gains electrons, forming a positive electromotive force from the positive pole to the negative pole.

[0012] The following reactions occur during charging:

[0013] positive electrode:

[0014] negative...

Abstract

This invention provides a alkaline lead-zinc storage battery applying PbO2 as the positive, zinc as the negative and KOH as the electrolyte to utilize the oxidation-reduction reaction of PbO2 and zinc in KOH solution to generate electronic transfer realizing charge and discharge of the battery.

Description

Technical field [0001] The invention is a storage battery. Background technique [0002] Current storage batteries include lead-acid batteries for acidic batteries, lithium batteries for alkaline batteries, nickel-metal hydride batteries, nickel-cadmium batteries, and iron-nickel batteries (see Chapter 1 "Chemical Batteries" of "Electrode Potential and Its Application" by Zhejiang People's Publishing House) . Because the lead in the lead-acid battery pollutes the environment, the negative electrode lead and sulfuric acid will react slowly to form self-discharge, resulting in short storage time, large power loss, and the positive electrode is easy to fall off, and the number of cycle discharges is small. Lithium batteries are rare resources because lithium resources are less in nature, so the cost is high. Nickel-hydrogen, nickel-cadmium, and iron-nickel batteries are also unfavorable in the promotion of large-capacity batteries due to the high cost of nickel. At present, ...
