Method for manufacturing magnetizing lead acid accumulator without vulcanizing

Abstract

The invention discloses a preparation method for a lead-acid storage battery which is exempt from vulcanization and magnetization, which relates to the field of storage batteries, and comprises various existing lead-acid storage batteries. The preparation method of the invention is characterized in that: at least one magnetic source is arranged on a newly designed and produced storage battery according to requirement, or at least one magnetic source is added on a produced storage battery, the outside of the magnetic source is provided with a magnetic shielding layer, the magnetic source is optimally arranged at the bottom of the storage battery, and the direction of a magnetic line is ensured to be parallel to the current direction on a polar plate. When in use, as the migration trace of the vector water molecular cluster of a charged ion and an electrolyte migrating between the polar plates is perpendicular to a magnetic field, the motion direction of the vector water molecular cluster can be changed under the action of the magnetic field, and the vector water molecular cluster can be cut into small micelle, thus increasing the activity of ions, improving the diffusion, the permeability and the lead sulfate crystal solubility of the electrolyte, avoiding the occurrence of a heavy vulcanization phenomenon, increasing battery capacity and the rate of electrochemical reaction, prolonging the service life, reducing using cost, decreasing repeated production, and playing a vital role on energy conservation and environmental protection.

Problems solved by technology

[0008] However, in the actual use of lead-acid batteries, due to frequent charge and discharge or long-term use or storage in a discharged state with the increase in use time, many large irreversible lead sulfate crystals will be produced on the active material of the plate. When this phenomenon occurs, the active material on the plate will seal the micropores on the active material on the plate due to the expansion of the large irreversible lead sulfate crystals, so that the electrolyte cannot penetrate into the active material, blocking ions, Electronic gain and loss (oxidation, reduction) conversion channels increase the internal resistance of the battery, so that most of the active materials on the plate cannot participate in the electrochemical reaction, reduce the effective area of ​​the plate reaction, and reduce the battery capacity and load capacity.

When this phenomenon occurs, conventional charging methods cannot dissolve large irreversible lead sulfate crystals to restore battery capacity, resulting in a battery with a designed service life of 3-5 years, which will die due to sulfuration in only 1-2 years, or even a few months. Severe and premature failure

According to the survey, 70% of the lead-acid batteries currently in use in the market are scrapped due to premature vulcanization. Due to the premature vulcanization of lead-acid batteries, not only a large amount of repeated purchase and maintenance costs have been added to the user out of thin air, but also due to The main raw materials of lead-acid batteries are heavy metal lead and dilute acid, which will bring serious pollution to the environment and a great waste of energy and resources in the process of production and waste product recycling

Therefore, due to the shortening of its service life, the production and recycling cycle rate is accelerated, and the burden of environmental protection and energy and resource consumption is aggravated.

[0009] In order to solve the above problems, the method usually used at present is to use the method of resonant compound pulse in combination with the method of resonant compound pulse to increase the vibration amplitude of the lead sulfate crystal nucleus, smash the irreversible large lead sulfate crystals and repair the severely vulcanized battery, although this method It can crush some large irreversible lead sulfate crystals to recover part of the battery capacity, but due to the volume expansion during the formation of large irreversible lead sulfate crystals, physical loosening has occurred between the active material and the plate grid. Using a resonant composite pulse to increase its resonance amplitude and crush the irreversible lead sulfate crystals is undoubtedly adding insult to injury. It will cause the active material to loosen and fall off while crushing the irreversible lead sulfate crystals, which will further aggravate the physical damage of the battery. At the same time, due to the shedding of the active material, it will cause a short circuit between the positive and negative plates and damage the battery, or cause the battery to experience thermal runaway during charging. When this phenomenon occurs, a large amount of oxygen will be released from the battery, resulting in oxidation of the grid. The phenomenon of water loss in the battery will increase the proportion of sulfuric acid in the electrolyte, increase the corrosion, and bend the plate, which will seriously affect the use efficiency of the battery and shorten its service life, and even cause the shell of the sealed battery to swell and bulge, or even explode. endanger personal and property safety
