[0037] At present, during the charging and discharging process of the lead-acid storage battery, the positive grid will be obviously corroded due to high battery temperature, and acid or organic salt contained in the electrolyte, and the grid composition in the initial state cannot be obtained.

[0038] On this basis, the present application provides a detection method and auxiliary equipment for analyzing the corroded grid composition in the battery, for analyzing the corroded grid composition of the lead-acid storage battery. The detection method of the present application can avoid the interference of the corrosion layer and impurity elements in the battery, and the detection result is accurate.

[0039] The present application will be described in detail below in combination with specific embodiments. The present embodiment detects the grid of the lead-acid storage battery produced by the same process, the same production line and the same batch.

[0040] Examples 1-5

[0041] This embodiment analyzes the detection method of the corroded grid component in the battery, including the following steps:

[0042] I. Preparation of the sample, specifically, the preparation of the sample includes the following steps:

[0043] (1) After dissecting the battery, the electrode plate is taken out, the active material on the surface of the electrode plate is removed, and the grid in the battery is taken out, as shown in Figure 1 At this time, the grid surface contains some adhered lead powder and corrosion layer.

[0044] (2) Put the grid into a container and treat it with a cleaning solution, then wash it with pure water and dry it, wherein the cleaning solution has reducing property and can dissolve the residual on the surface of the grid, so that the grid exposes its metal color, as shown in Figure 2

[0045] In this embodiment, the cleaning solution is a sugar base solution, the mass percentage of sugar base in the sugar base solution is 20%, the mass ratio of sugar to base in the sugar base solution is 2:1, the sugar in the sugar base solution is glucose, and the base is sodium hydroxide.

[0046] In this embodiment, the grid is subjected to micro-boiling treatment in the sugar base solution under heating conditions, and the heating temperature is 85°C.

[0047] The sugar base solution is selected in this embodiment because under alkaline conditions, glucose will undergo ring-opening reaction to generate aldehyde and carboxylic acid with open-chain structure, which has stronger reducing property and can dissolve the surface material of the grid under heating conditions to expose its metal color. This component is similar to the component of the grid itself. At the same time, glucose and sodium hydroxide are easy to obtain and have low cost.

[0048] (3) Take the dried grid or part of its structure and inlay it in pure lead as a sample.

[0049] In this embodiment, the part of the grid structure is the tab of the grid, that is, the tab is inlaid in pure lead as a sample in this embodiment, and attention should be paid to the flatness of the sample during treatment of the sample to avoid interference with the detection data.

[0050] II. Test the sample with a direct-reading spectrometer and record the data

[0051] ​Since the positive plate grid is generally made of lead calcium tin aluminum alloy, the lead-based general analysis program Pb-01 should be selected for testing when testing the grid alloy, and the sample should be selected to calibrate the equipment first. If the Sn content of the alloy to be tested is about 1.2%, a lead alloy standard sample with Sn content of about 1.2% can be selected for calibration, and the same is true for other elements. Sometimes a standard sample can calibrate multiple elements at the same time. In order to ensure the accuracy of the results, argon with a purity of more than 99.999% should be selected as the protective gas. After calibrating the equipment, the sample is excited, and the same sample is excited at least twice, and the data is recorded.

[0052] In this embodiment, the direct-reading spectrometer has the detection capability of Ca, Sn, Al, Ag, Cu, Bi, S, Te, Mg, Pb elements,

[0053] The analysis spectrum and detection limit of each element are as follows:

[0054] Ca: 315.887 nm, 0.00020%-1.3%

[0055] Sn: 317.505 nm, 0.00010%-1.3%

[0056] Al: 309.271 nm, 0.000010%-0.0750%

[0057] Ag: 338.289 nm, 0.000050%-0.0250%

[0058] Cu: 324.753 nm, 0.00001%-0.0150%

[0059] Bi: 306.772 nm, 0.000050%-1.2%

[0060] S: 180.731 nm, 0.00010%-0.0110%

[0061] Te: 214.28 nm, 0.00010%-0.100%

[0062] Mg: 279.077 nm, 0.000050%-0.180%.

[0063] In the lead-based direct-reading spectrometer, the Pb content is 100% minus the sum of other impurity elements. Ca, Sn, Al, Ag, Cu, Bi, S, Te, Mg basically contain the impurity elements present in lead.

[0064] The weight change of the grid treatment in Examples 1-5 is shown in Table 1.

[0065] Table 1 Weight change of grid treatment in Examples 1-5

[0066]

[0067] In the above examples, the surface oxide layer of the grid is not completely reduced due to the low glucose content in the sugar base solution.

[0068] In this embodiment, if the active substance needs to be analyzed, the following steps can also be included: washing the surface of the plate with water to pH 6-7, drying the plate, and removing the plate after complete drying and knocking off the active substance to be tested. The active substance here mainly refers to the substance in the battery that participates in the electrochemical reaction. The positive active substance is closely related to the charge and discharge state of the battery. When the battery is dissected, the discharge state can be judged according to the lead dioxide content in the active substance. Currently, the active substance is generally titrated with EDTA solution.

[0069] Embodiments 6-10

[0070] When the grid is treated with a sugar base solution, the surface area of the grid is large, the corrosion area is large, and the sugar base solution is consumed too quickly, which is easy to cause waste. Moreover, only the tabs are treated in subsequent operations. Therefore, in order to avoid waste and save costs, the applicant usually cuts off the grid tabs first, and then puts the tabs into the sugar base solution for micro-boiling treatment. Specifically, the detection method for analyzing the components of the corroded grid in the battery in this embodiment includes the following steps:

[0071] I. Preparing a test sample, specifically, preparing a test sample includes the following steps:

[0072] (1) After dissecting the battery, the plate is removed, the active substance on the surface of the plate is removed, and the grid in the battery is taken out, at this time the surface of the grid contains part of the adhered lead powder and the corrosion layer.

[0073] (2) Part of the structure of the grid is taken into a container, treated with a cleaning solution, then washed with pure water, and dried, wherein the cleaning solution has reducing property and can dissolve the residual on the surface of the grid, so that the grid exposes its metal color.

[0074] In this embodiment, the cleaning solution is a sugar base solution, the mass percentage of sugar base in the sugar base solution is 20%, the mass ratio of sugar to base in the sugar base solution is 3:1, the sugar in the sugar base solution is glucose, and the base is sodium hydroxide.

[0075] In this embodiment, the grid is micro-boiled in the sugar base solution under heating conditions, and the heating temperature is 90°C.

[0076] In this embodiment, part of the structure of the grid is the tab of the grid, that is, the tab is put into a container, treated with a cleaning solution, then washed with pure water, and dried.

[0077] (3) The lug after drying is inlaid in pure lead as a sample. When processing the sample, attention should be paid to the flatness of the sample and no gap should exist to avoid interfering with the test data.

[0078] II. Test the sample with a direct-reading spectrometer and record the data

[0079] Since the positive plate grid is generally made of lead-calcium-tin-aluminum alloy, when testing the grid alloy, the lead-based general analysis program Pb-01 should be selected for testing, and the standard sample should be selected to calibrate the equipment first. If the Sn content of the alloy to be tested is about 1.2%, a lead alloy standard sample with Sn content of about 1.2% can be selected for calibration, and the same applies to other elements. Sometimes one standard sample can calibrate multiple elements at the same time. In order to ensure the accuracy of the results, argon with a purity of more than 99.999% should be selected as the protective gas. After calibrating the equipment, the sample is excited, and the same sample is excited at least twice, and the data is recorded.

[0080] In this embodiment, the direct-reading spectrometer has the detection capability of Ca, Sn, Al, Ag, Cu, Bi, S, Te, Mg, and Pb elements,

[0081] The analysis spectrum lines and detection limits of each element are as follows:

[0082] Ca: 315.887 nm, 0.00020%-1.3%

[0083] Sn: 317.505 nm, 0.00010%-1.3%

[0084] Al: 309.271 nm, 0.000010%-0.0750%

[0085] Ag: 338.289 nm, 0.000050%-0.0250%

[0086] Cu: 324.753 nm, 0.00001%-0.0150%

[0087] Bi: 306.772 nm, 0.000050%-1.2%

[0088] S: 180.731 nm, 0.00010%-0.0110%

[0089] Te: 214.28 nm, 0.00010%-0.100%

[0090] Mg: 279.077 nm, 0.000050%-0.180%.

[0091] In the lead-based direct-reading spectrometer, the content of Pb is 100% minus the sum of other impurity elements. Ca, Sn, Al, Ag, Cu, Bi, S, Te, and Mg basically include the impurity elements present in lead.

[0092] The weight changes of the grids in Examples 6-10 are shown in Table 2.

[0094]

[0095] In this embodiment, if the active substance needs to be analyzed, the following steps can also be included: washing the surface of the electrode plate with water to pH 6-7, drying the electrode plate, and knocking off the active substance to be tested after complete drying. The active substance here mainly refers to the substance in the battery that participates in the electrochemical reaction. The positive active substance is closely related to the charge and discharge state of the battery. When the battery is dissected, the discharge state can be judged according to the content of lead dioxide in the active substance. Currently, the active substance is generally titrated with EDTA solution.

[0096] Examples 11-15

[0097] The detection method in Examples 11-15 is different from the detection method in Examples 6-10 in that the cleaning solution is a sugar base solution, the mass percentage of sugar base in the sugar base solution is 20%, the mass ratio of sugar to base in the sugar base solution is 4:1, the sugar in the sugar base solution is glucose, and the base is sodium hydroxide.

[0130]

[0131] As shown in Table 8, the detection method of the present application can avoid the interference of the corrosion layer and impurity elements in the battery, and the detection result is accurate.

[0132] Since the tab is small, it is not easy to take out from the container, and the glucose undergoes caramelization reaction, and the solution gradually changes from transparent to brown and black, so that it is impossible to determine whether the tab is cleaned or not through the beaker. To solve the above technical problems, the present application provides the following specific embodiments.

[0133] As shown in Figures 3-5 , the detection method for analyzing the composition of the corroded grid in the battery uses an auxiliary device for analyzing the composition of the corroded grid in the battery, which comprises a box body 1, a lifting basket 2 and a driving mechanism.

[0134] In this embodiment, the box body 1 is made of a ceramic material resistant to high temperature and alkali, and is used to place the cleaning solution. The box body 1 comprises a bottom and a side wall extending upward from the bottom, and the bottom and the side wall together enclose a space for containing the cleaning solution.

In this embodiment, the part of the structure of the grid is the tab of the grid.

[0136] Specifically, four support columns 11 are arranged on the inner side of the side wall of the box body 1, and the lifting basket 2 is slidingly arranged on the support columns 11. A driving mechanism drives the lifting basket 2 to slide up and down, so as to adjust the height of the lifting basket 2, facilitating observation of the cleaning state of the current grid or tab. The driving mechanism here can be electric or manual. The electric driving mechanism can be motor-driven, and the manual driving mechanism can be hand-held rocker-driven.

[0137] In this embodiment, the side wall of the lifting basket 2 is provided as a transparent plate, which can be made of a light-transmitting material, preferably polyhexamethylene terephthalamide. This material has high light transmittance, which facilitates observation of the state of the tabs in the lifting basket 2, and has the characteristics of high temperature resistance, stable chemical properties, etc., meeting the requirements.

[0138] In this embodiment, the bottom of the lifting basket 2 is provided with a plurality of through holes 21. At the same time, the area of the plurality of through holes 21 is greater than or equal to 1 / 3 of the area of the bottom of the lifting basket 2 and less than or equal to 2 / 3 of the area of the bottom of the lifting basket 2.

[0139] The arrangement of the through holes 21 can ensure that the state of the grid can be more clearly observed when the lifting basket 2 is lifted. At the same time, the limitation of the area of the through holes 21 ensures the strength of the lifting basket 2 and the descending speed of the sugar alkali solution, facilitating observation and saving time.

[0140] In this embodiment, a partition plate 24 is arranged in the lifting basket 2, which divides the interior of the lifting basket 2 into at least two storage spaces 22.

[0141] The arrangement of the plurality of storage spaces 22 can simultaneously clean the tabs of a plurality of grids, improving efficiency. The limitation of the connecting holes 23 ensures the strength of the lifting basket 2 and facilitates the descent of the sugar alkali solution when the lifting basket 2 is lifted, exposing the tabs and facilitating observation of the cleaning degree of the tabs.

[0142] In this embodiment, a heating device 3 is arranged at the bottom of the box body 1, which is used to heat the cleaning liquid. The heating device 3 here is a conventional means.

[0143] In this embodiment, a stirring device 4 is arranged at the center of the bottom of the box body 1, which is used to stir the cleaning liquid, so as to ensure the uniformity of the liquid temperature in the box body 1 and prevent the sugar alkali solution from suddenly boiling over and causing injury.
