[0027] The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some but not all embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will satisfy applicable legal requirements. Throughout, like reference numerals denote like elements. As used in the specification and in the appended claims, the singular forms "a", "an", "the" include plural referents unless the context clearly dictates otherwise.

[0028] In order for lead-acid batteries to maintain their energy parameters for extended periods of time, the sulfuric acid electrolyte solution must be homogeneous throughout the cell. Homogeneity of the acid in the electrolyte in a lead-acid cell is a requirement for the performance of all types of lead-acid batteries. However, this condition applies to the highest degree to valve-regulated lead-acid batteries, where the possibility of electrolyte homogenization is difficult.

[0029] To fully illustrate the necessity of electrolyte homogenization for the efficient and reverse performance of electrochemical processes during battery operation, this article discusses the mechanism of the charge and discharge reactions of a lead-acid cell. The speed of the electrochemical reactions inside a lead-acid battery depends on the electrode potential, temperature, electrolyte concentration, sulfuric acid solution concentration, and the composition and additives in the active electrode materials. The chemical composition of the material of the alloy of the conductive grid of the positive and negative electrodes is also a factor. These factors are derived from the following electrochemical processes performed during battery operation:

[0030] Charging reaction at the positive electrode:

[0031] (1)PbSO4+2H2O→PbO2+2H++H2SO4+2e -

[0032] Charging reaction at the negative electrode:

[0033] (2)PbSO4+2H++2e - →Pb+H2SO4

[0034] (3)Pb+1 / 2O2+H2SO4→PbSO4+H2O+Q 热

[0035] In addition to these charging reactions taking place at the electrodes, the following chemical decomposition of water occurs:

[0036] (4)H2O→2H++1 / 2O2+2e-

[0037] Additional reactions through different mechanisms include:

[0038] Chemical Mechanism:

[0039] (5)PbSO4+2H++2e - →Pb+H2SO4

[0040] Electrochemical mechanism:

[0041] (6) 1 / 2O2+2H+=2e - →H2O

[0042] During discharge, the following electrochemical reactions occur at the positive electrode of the cell:

[0043] (7)PbO2+2H+H2SO4+2e - →PbSO4+2H2O

[0044] During discharge, the following electrochemical reactions occur at the negative electrode of the cell:

[0045] (8) Pb + H2SO4 → PbSO4 + 2H + +2e -

[0046] As indicated by the electrochemical reaction shown above, at the beginning, water is consumed on the positive electrode and then the execution of the process of water decomposition and separation of oxygen begins. While charging, water is formed on the negative electrode. When the concentration of separated oxygen reaches a threshold, it begins to decrease on the negative electrode generating heat.

[0047] In order to drive the above reactions, an acceptable volume and concentration of sulfuric acid must be present throughout the unit. From the reactions shown above, in order to maintain the thermodynamic equilibrium of the Pb / PbO2 system ratio, it is necessary to keep the sulfuric acid concentration in the volume of the unit within certain limits.

[0048] The voltage of a lead-acid cell at equilibrium is about 2 V. This voltage value indicates that when the voltage value of the lead-acid cell is below 2 V, the reaction inside the cell causes Pb2 + The formation of, thus leading to an imbalance and ultimately to discharge. Alternatively, when the voltage value of the lead-acid cell is higher than 2V, the electrochemical reactions occurring in the cell lead to the formation of Pb and PbO2, leading to the opposite imbalance, but still ultimately leading to the discharge of the cell. While the mass values ​​of the positive and negative electrodes inside the lead-acid cell are taken into account, the balance value of water should also be considered. This potential balance value for the H2O / O2 pair is approximately 1.23V, and the potential balance value for the H2 / H2O pair is 0V. These values ​​indicate the formation of redox pairs in the lead-acid elements, a process described in the Nernst equation as follows:

[0049] [Equation 1] Е0=Е 0,标准+RT / nF[(Ox / (Red)]

[0050] The Nernst equation shows that in lead-acid elements, except for Pb / Pb 2+ and Pb 2+ / Pb 4+ In addition to the alkaline redox pairs, H2O / O2 and H2 / H2O (H2 / H3O + and ΟH - The secondary oxidation-reduction couple of / O2) also participates in the reaction because the electrolyte is an aqueous solution of sulfuric acid. This means that in order to fully complete the electrochemical process of charging and discharging in the lead-acid cell and battery, it is necessary to make the concentration of this electrolyte the same and available in all the volumes of the cell in the lead-acid battery, in the volume of the separator and in both the volume of the positive electrode and the volume of the negative electrode respectively.

[0051] The requirements for electrolyte homogeneity apply to a large extent to the valve-regulated lead-acid batteries widely used today, which differ significantly in their construction from other types of lead-acid batteries. In many lead-acid cells, the electrolyte solution of sulfuric acid is absorbed in the volume of the diaphragm by an absorbed glass matt (AGM), a pore system formed by fine glass fibers. The AGM diaphragm performs two functions, the first of which is to separate the positive and negative electrodes, and the second is to keep the necessary amount of electrolyte in the cell of the lead-acid battery within its volume. Precisely due to its specific construction, by using glass matts in this type of lead-acid battery, the conditions are created for effectively carrying out the water recombination of the oxygen and hydrogen released during charging. The possibility of operating the valve-regulated lead-acid battery under the conditions of a closed oxygen cycle significantly reduces the loss of water during its charging, resulting in an extended operating cycle.

[0052] The mechanism of obtaining the stratification effect is also clearly presented, since it takes an extended period of time for sulfuric acid to diffuse from places with a higher concentration to places with a lower concentration in the volume of a lead-acid battery. As an example, when a lead-acid battery is charged, the concentration increases over time and a charge is formed in the porous volume of the positive and negative electrodes due to sulfuric acid on the positive and negative electrodes. Since the electrolyte contained in this porous volume accounts for 20% of the total volume of the electrolyte inside the lead-acid battery, the concentration of electrolyte found in the pores of the electrodes becomes much higher than the concentration of sulfuric acid in the total volume of the electrolyte contained in the rest of the internal parts. In these cases, the concentration of sulfuric acid in the pores of the electrodes is high and it is much heavier than the acid in the volume of the separator and the free volume in the cell. When sulfuric acid begins to leave the structural pores of the electrode, it begins to flow towards the bottom of the cell, creating the effect of a sludge or stratification of the solution of sulfuric acid in the electrolyte, which has a detrimental effect on charging. This stratification of the electrolyte is the reason for obtaining a lower voltage in the upper part of the electrode, where the electrolyte is more diluted, while in the lower part of the electrode in the lead-acid cell, the voltage has a higher value due to the increased electrolyte concentration.

[0087] Example

[0088] Example 1

[0089] In this example, a method and device for homogenizing the electrolyte in a lead-acid battery is used on the unit during charging. For this purpose, a valve-regulated lead-acid battery with a capacity of 180 Ah declared by the manufacturer is selected. The battery is operated in floating charge mode. Before starting the electrolyte homogenization procedure of the selected battery, the values ​​of the internal resistance and the open circuit voltage are measured. These values ​​are shown in the following Table 1.

[0090] After measuring the internal resistance and open circuit voltage, the battery is placed in the battery container of the device. Next, the battery is balanced by a dynamometer and fixed on a shaft connecting the centers of two self-aligning bearings. Next, the control inverter is turned on to supply and control the motor reducer. The control inverter is used to adjust the rotation speed, which is maintained at 18rpm-20rpm. The device then performs an electrolyte homogenization procedure by rotating the battery for 1.5 hours.

[0091] The internal resistance and open circuit voltage values ​​were then measured and the obtained values ​​are reflected in Table 1.

[0092] Table 1 - Table showing cell characteristics before and after electrolyte homogenization

[0093] Internal resistance Open circuit voltage Before homogenization <![CDATA[InR1=4,03mΩ]]> <![CDATA[OCV1=12,29V]]> After homogenization <![CDATA[InR2=3,57mΩ]]> <![CDATA[OCV2=12,31V]]>

[0094] The results reported after completing an electrolyte homogenization procedure in a lead-acid battery illustrate the effect of the device on internal resistance and open circuit voltage. Specifically, use of the device resulted in the battery exhibiting reduced internal resistance while exhibiting only minimal changes in open circuit voltage values.

[0095] Example 2

[0096] In this example, an electrochemical restoration program is applied while homogenizing the electrolyte in the battery to restore the energy parameters of a lead-acid battery in service or storage. An electrochemical restoration program is a specialized charging program with defined values ​​for current, voltage and total execution time. An electrochemical restoration program is used to determine the parameters of the selected battery. The choice of an electrochemical program to restore the energy parameters of batteries depends on their degree of charge, battery type and size, which determines their energy capacity and the regime in which they are put into service.

[0097] For this example, a 180Ah valve-regulated battery was used. The values ​​selected for this battery constitute an electrochemical recovery procedure designated "EL1" and involve I ch1 =18A charging current and U ch1 = Limited charging voltage value of 14.4V for 16 hours.

[0098] The 180Ah valve-regulated battery is operated in float charge mode. The recovery procedure includes the following technical steps in the following order:

[0099] (1) The internal resistance and open circuit voltage values ​​of the selected battery were measured. Then, the battery was placed in a homogenization device in the same order and in the same operation as described in Example 1.

[0100] (2) The battery is electrically connected to the programmable charging device via a connector (in this example, a slip ring is used).

[0101] (3) Turn on the control inverter, which supplies power to the motor and controls the motor, and the speed of the battery is set at 10 rpm-12 rpm.

[0102] (4) While causing the battery to rotate, turn on the programmable charging device to execute an electrochemical process to restore the energy parameters of the battery.

[0103] Example 3

[0104] The 180Ah valve-regulated battery was operated in a float charge mode until the battery needed to be restored. To begin restoring the energy parameters of the battery, the battery was placed in an electrolyte homogenization device. The battery was then subjected to a rotational motion at a rotational speed of 10rpm-12rpm while engaging a programmable charging device to perform the EL1 electrochemical program and a patented bipolar overvoltage battery pulse generator (BEAT) device manufactured by WaveTech GmbH Germany. The results of this experiment are discussed in Example 4 below.

[0105] Example 4

[0106] To support the results of the methods and apparatus disclosed herein, three nearly identical cells were run for the same length of time at the same location and under the same conditions. The discharge capacity of each of the three cells was measured. These values ​​are shown in Table 2. The standard deviation of the discharge capacity was 0.28 Ah, indicating that it is suitable for comparison. Next, each cell was treated with the recovery method described as follows:

[0107] Only the first cell B1 was treated using the electrochemical restoration procedure (EL1).

[0108] A second cell B2 was processed using the apparatus and methods disclosed herein for electrolyte homogenization in conjunction with the EL1 electrochemical procedure (as described in Example 2).

[0109] A third cell B3 was processed using the apparatus and methods disclosed herein for electrolyte homogenization in combination with the EL1 electrochemical procedure and the BEAT apparatus (as described in Example 3).

[0110] After processing the cells, the discharge capacity of each cell was measured. These values ​​are shown in Table 2 and are Figure 6 Medium picture.

[0111] Table 2. Discharge capacity before and after battery treatment

[0112]

[0113] After the treatment, the discharge capacity value of battery B2 was 10.4% higher than that of battery B1. The discharge capacity value of battery B3 was more improved than that of battery B2. Battery B3 had a discharge capacity value 13% higher than that of battery B1.

[0114] The results of this experiment clearly support that the device and method disclosed herein significantly increase the efficiency of the procedure for restoring the energy parameters of a battery.

[0115] Modifications of the invention set forth herein will occur to those skilled in the art with the benefit of the teachings presented in the foregoing description and the associated drawings. Therefore, it should be understood that the invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for the purpose of limitation.
