Embodiment approach

[0037] A method for internalizing the magnetic force of a power-type lead storage battery, comprising the following steps:

[0038] (1) Acid filling: Pour sulfuric acid solution into the lead storage battery through an acid pot, and then let it stand for 1 to 2 hours. The amount of sulfuric acid solution added to a single cell of the lead storage battery is 11 to 13ml / Ah, and the density of the sulfuric acid solution is 1.28-1.32g / cm 3 .

[0039] (2) The battery treated in step (1) is first charged with a current of 0.05-0.1C for 2 to 3 hours, and then charged with a current of 0.1-0.2C for 3 to 5 hours. During this process, an electromagnetic field is applied to the formed battery A: Frequency 12~18kHz, the power is 150~180 milliwatts, and the electromagnetic field is adjusted to the opposite polarity.

Abstract

The invention discloses a magnetic force internal formation method of a power-type lead accumulator. The magnetic force internal formation method of the lead accumulator applies generation of a low-energy magnetic field to influence on intensity of lead accumulator in chemical reaction, charge transfer in solution and metal medium and transmission rate. At the early period of the discharge of the formation battery, the magnetic field system current is also influenced by an external physical magnetic field, its frequency and power are adjusted to reduce the polarization degree; at the post period of the formation discharge, the magnetic field intensity is modulated to change electronic transmission rate and intensity; formation of a large lead sulfate grain can play very good suspending effect; moreover, electromagnetic fields with different intensities are modulated generally to generate waves with low frequency and high frequency so as to increase the mobility of sulfuric acid solution; thus the acid liquid stratification in the battery formation process is solved.

Description

technical field [0001] The invention relates to an internalization method of a lead storage battery, in particular to a magnetic internalization method of a power type lead storage battery. Background technique [0002] Valve-regulated lead-acid batteries have been widely used in power systems in industries such as electric power, communications, transportation, finance, and military forces, whether they are backup batteries in substations, computer rooms, mobile base stations, UPS, etc., or starting batteries for generator sets. Etc., especially in the application of electric bicycles, the rapid and rapid development period has been achieved in recent years, and the requirements for battery products are getting higher and higher. The early capacity attenuation, insufficient capacity and short cycle life of the battery have become constraints to its rapid development. Constraints. [0003] In the manufacturing process of the battery, it is necessary to activate the positive...
