[0033] In the field of lithium batteries, X-rays are often used to detect and analyze the structure and performance of lithium batteries. X-ray technology is a non-destructive detection method that can be used to observe the microstructure and material distribution inside the battery. After the lamination process of lithium batteries is completed, the internal positive and negative electrode coating needs to be inspected. The alignment of the positive and negative electrode sheets is very important, and x-ray detection equipment is often used to detect them. Currently, before X-ray detection, process engineers generally use CAD to draw and simulate the X-ray incident angle, the upper and lower limits of the alignment of the stacked positive and negative electrode sheets to formulate the X-ray alignment standard, and then input the converted X-ray alignment standard into the equipment as a basis for judgment. When the incident angle, etc. changes, it is necessary to re-draw and simulate, resulting in low efficiency. Based on the above technical problems, an embodiment of the present invention proposes a method for detecting the status of a battery. Figure 2 is a flow chart of a method for detecting a battery status according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0034] Step S202, obtaining a target battery edge alignment standard based on the target account input, wherein the target battery edge alignment standard represents the distance between the positive and negative electrode sheets of the target battery under normal circumstances.

[0035] In this step, the alignment standard of the edge of the target battery may be first obtained, and the alignment standard is the distance between the positive and negative electrode sheets of the target battery under normal conditions. Figure 3 is a schematic diagram of a battery electrode in a battery status detection method according to an optional embodiment of the present invention, such as Figure 3As shown, the outer circle represents the negative electrode of the battery, the inner circle represents the positive electrode of the battery, a represents the alignment of the upper (or lower) edges of the positive and negative electrodes of the stack, and b represents the alignment of the left (or right) edges of the stack. Normally, the alignment standards corresponding to a and b are 2±0.6mm for a and 1±0.6mm for b.

[0036] Step S204, obtaining the actual alignment value of the positive and negative electrode sheets of the target battery at the target incident angle, wherein the target incident angle is the angle at which the alignment of the positive and negative electrode sheets of the target battery is detected by irradiating the target battery with x-rays.

[0037] In this step, the actual alignment value of the positive and negative electrodes of the target battery at the target incident angle is obtained. The incident angle here is the angle at which the target battery is irradiated when using x-rays to detect the target battery. Figure 3 As shown, the x-ray, i.e. the incident light, is irradiated on the positive and negative electrodes in parallel, wherein W is the tangent point between the x-ray and the outer circle, i.e. the negative electrode, and Z is the tangent point between the positive electrode and the perpendicular foot of the other incident light, i.e. O. The distance OW is the required alignment value, i.e. the actual alignment value.

[0038] Step S206, based on the target corresponding relationship between the incident angle, the battery edge alignment standard and the alignment standard value, and the target incident angle and the target battery edge alignment standard, determine the target alignment standard value corresponding to the target battery at the target incident angle.

[0039] In this step, the target correspondence between the incident angle, the battery edge alignment standard and the alignment standard value can be determined, wherein the target correspondence can be presented in the form of a curve, a calculation formula, etc. Then, according to the target incident angle and the target battery edge alignment standard, the target alignment standard value under the target incident angle can be determined. For example, when the target correspondence is a calculation formula, the target incident angle and the target battery edge alignment standard can be substituted into the calculation formula to obtain the target alignment standard value.

[0040] Step S208 , determining the state of the target battery based on the actual alignment value and the target alignment standard value.

[0041] In this step, the relationship between the actual alignment value and the target alignment standard value can be determined to determine the state of the target battery. For example, the deviation between the actual alignment value and the target alignment standard value can be determined. Within a certain range, the alignment of the positive and negative electrodes of the target battery is considered to be in compliance with the standard and in a normal state. If the deviation exceeds the range, the target battery is considered to be abnormal. The target alignment standard value can also be an alignment range. If the actual alignment value is within this range, the target battery is considered to be normal. If it is not within this range, it is considered to be abnormal.

[0042] Through the above steps, the purpose of determining the alignment standard according to the corresponding relationship between the incident angle, the battery edge alignment standard and the alignment standard value is achieved, thereby realizing the technical effect of improving the efficiency of detecting the alignment of the positive and negative electrodes of the battery, thereby solving the technical problem that the current use of x-rays to detect the alignment of the positive and negative electrodes of the battery requires first drawing a diagram to simulate the x-ray incident angle to formulate the alignment standard, and each time the incident angle is changed, the drawing must be re-drawn, resulting in low efficiency in detecting the alignment.

[0043] As an optional embodiment, before determining the target alignment standard value corresponding to the target battery at the target incident angle based on the target correspondence between the incident angle, the battery edge alignment standard and the alignment standard value, as well as the target incident angle and the target battery edge alignment standard, it includes: obtaining the target battery type of the target battery; selecting the correspondence between the incident angle corresponding to the target battery type and the battery edge alignment standard as the target correspondence.

[0044] Optionally, if you want to determine the target corresponding relationship, you can first determine the type of the target battery. Because different battery types may correspond to different corresponding relationships, therefore, you can first obtain the target battery type of the target battery, and then select the corresponding corresponding relationship as the target corresponding relationship.

[0045] As an optional embodiment, before determining the target alignment standard value corresponding to the target battery at the target incident angle based on the target correspondence between the incident angle, the battery edge alignment standard and the alignment standard value, as well as the target incident angle and the target battery edge alignment standard, it includes: constructing a virtual structure corresponding to the target battery; simulating x-ray irradiation of the virtual structure corresponding to the target battery, and determining the target correspondence according to the incident angle, the battery edge alignment standard and the alignment standard value in the virtual structure.

[0046] Optionally, a virtual structure corresponding to the target battery may be constructed first, and then the virtual structure corresponding to the target battery may be irradiated by simulating x-rays, and the target correspondence relationship may be determined according to various values ​​in the virtual structure. Figure 4 is a schematic diagram of a simulated battery electrode in a battery status detection method according to an optional embodiment of the present invention, such as Figure 4 As stated above, Figure 3 The difference is that Figure 4 Lieutenant General Figure 3 The corner of the negative electrode is simulated as a right angle corner, but in actual practice it is usually Figure 3 For the convenience of calculation, we can first construct the arc corner shown in Figure 4The virtual structure shown. Among them, the x-ray is irradiated on the positive and negative electrodes in parallel, and the incident angle is C. The outer circle represents the negative electrode, and the inner circle represents the positive electrode. The tangent point of the x-ray with the negative electrode is X, and the tangent point with the positive electrode is Z. The perpendicular point of Z and the negative electrode is Y, and the foot of X and the other incident light is O. A, B, and C represent angles. a represents the alignment of the upper (or lower) edge of the positive and negative electrodes of the stack, and b represents the alignment of the left (or right) edge of the stack. Generally, a is 2±0.6mm and b is 1±0.6mm. Figure 5 Schematic diagram of the design of the R angle of the conventional positive electrode sheet of a battery according to the battery status detection method provided by an optional embodiment of the present invention, such as Figure 5 As shown, the die-cutting angle is usually 45°, the die-cutting depth is 3±0.2mm, the boss is 0.25±0.2mm, and R1 is a smaller fillet. The die-cutting angle refers to the angle of the die-cutting tool relative to the reference line or the edge of the electrode sheet during the die-cutting process of the battery positive electrode sheet. The die-cutting depth refers to the depth of the die-cutting tool cutting into the electrode sheet. The boss refers to a small raised part formed on the electrode sheet during the die-cutting process, which is usually caused by the extrusion or pressing of the material during the die-cutting process. The conventional negative electrode sheet is designed as R3, which usually refers to the corners or edges of the negative electrode sheet being rounded with a radius of 3 mm. Figure 4 For the convenience of calculation, it is assumed that the negative electrode is designed at a 90° right angle. Figure 4 In the equation, XY=a+3, ZY=b, so It is known that A+B+C=90°, so A+B=90°-C, and Therefore Then restore the negative electrode to rounded corners, such as Figure 3 As shown above, the OX value has been calculated. The actual X-ray projection required, that is, the alignment standard value is the length of OW, where R3 is equivalent to a circle with a radius of 3 being tangent to the straight line. In summary: The formula obtained is the calculation formula for the standard value of alignment corresponding to the battery with both positive and negative electrodes of conventional design.

[0047] As an optional embodiment, the target calculation formula is: Wherein, OW is the target alignment standard value, a and b are the upper limit value or the lower limit value of edge alignment, and C is the target incident angle.

[0048] According to this formula, the standard value of the target battery's alignment can be determined. Different battery types may affect some values ​​and structures, so it is necessary to determine the corresponding relationship based on the virtual structure of the battery. Substituting the above calculation logic into the device algorithm can eliminate manual calculations, save manpower and time, and the device can calculate itself when the device parameters or stacking alignment standards change.

[0049] As an optional embodiment, based on the target correspondence between the incident angle, the battery edge alignment standard and the alignment standard value, as well as the target incident angle and the target battery edge alignment standard, the target alignment standard value corresponding to the target battery at the target incident angle is determined, wherein the target correspondence is a target calculation formula, including: based on the target battery edge alignment standard, determining the edge alignment upper limit value and the edge alignment lower limit value; inputting the incident angle and the edge alignment upper limit value and the edge alignment lower limit value into the target calculation formula in sequence to obtain the alignment standard upper limit value and the alignment standard lower limit value, wherein the target alignment standard value includes the alignment standard upper limit value and the alignment standard lower limit value.

[0050] Optionally, when the target correspondence is a target calculation formula, the upper and lower limits of the edge alignment can be determined according to the target battery edge alignment standard. For example, the upper edge of the positive and negative electrodes is 2±0.6mm, and the right edge is 1±0.6mm. The upper limit of the upper edge is 2.6mm, and the lower limit is 1.4mm. The upper limit of the right edge is 1.6mm, and the lower limit is 0.4mm. The above values ​​can be substituted into the calculation formula, such as the calculation formula mentioned above. When the target incident angle is 45 degrees, substitute the upper limit value a as 2.6mm and b as 1.6mm, and the obtained OW is 3.8485. Substitute the lower limit value a as 1.4mm and b as 0.4mm into the formula, and the obtained OW is 2.1515. The upper limit value of the alignment standard is 3.8485, and the lower limit value of the alignment standard is 2.1515.

[0051] As an optional embodiment, the state of the target battery is determined based on the actual alignment value and the target alignment standard value, including: judging whether the actual alignment value is between the upper limit value of the alignment standard and the lower limit value of the alignment standard; when the actual alignment value is between the upper limit value of the alignment standard and the lower limit value of the alignment standard, determining that the state of the target battery is a normal state.

[0052] Optionally, it is determined whether the actual alignment value is between the upper limit value of the alignment standard and the lower limit value of the alignment standard. If it is between the upper limit value and the lower limit value, it is considered that the positive and negative electrodes of the target battery meet the standard, that is, it is a normal state. If it is not between the upper limit value and the lower limit value, it is considered that the positive and negative electrodes of the target battery do not meet the standard, that is, it is an abnormal state.

[0053] As an optional embodiment, actual alignment values ​​of the positive and negative plates of a target battery at multiple incident angles are obtained, wherein the target incident angle is one of the multiple incident angles; based on the target correspondence between the incident angle, the battery edge alignment standard and the alignment standard value, as well as the multiple incident angles and the target battery edge alignment standard, the alignment standard values ​​corresponding to each of the multiple incident angles are determined; it is determined in turn whether the actual alignment values ​​corresponding to each of the multiple incident angles match the corresponding alignment standard values; among the multiple incident angles, when the number of incident angles whose actual alignment values ​​match the corresponding alignment standard values ​​exceeds a preset number, it is determined that the state of the target battery is normal.

[0054] Optionally, the actual alignment value of the target battery at multiple incident angles can be measured, and then the corresponding alignment standard values ​​can be determined based on the multiple incident angles to determine whether the actual alignment value matches the corresponding alignment standard value at different incident angles. It can be determined whether the number of incident angles at which the actual alignment value matches the corresponding alignment standard value exceeds a preset number, and the preset number can be determined based on actual conditions. When it exceeds the preset number, it is considered that the positive and negative electrodes of the target battery meet the standard, which is a normal state. If it is lower than a preset threshold, it is considered that the positive and negative electrodes of the target battery do not meet the standard, which is an abnormal state. By measuring the actual alignment values ​​at multiple incident angles, the accuracy of the detection results can be improved.

[0058] The first acquisition module 62 is used to acquire a target battery edge alignment standard based on a target account input, wherein the target battery edge alignment standard represents the distance between the positive and negative electrodes of the target battery under normal circumstances.

[0059] The second acquisition module 64 is connected to the first acquisition module 62 and is used to obtain the actual alignment value of the positive and negative electrode sheets of the target battery at a target incident angle, wherein the target incident angle is an angle at which the positive and negative electrode sheets of the target battery are irradiated with x-rays to detect the alignment of the positive and negative electrode sheets.

[0060] The first determination module 66 is connected to the second acquisition module 64, and is used to determine the target alignment standard value corresponding to the target battery at the target incident angle based on the target correspondence between the incident angle, the battery edge alignment standard and the alignment standard value, and the target incident angle and the target battery edge alignment standard.
