The present application can improve the filling speed of the particles and the calculation speed of the model.

The server can use an independent server or a server cluster composed of multiple servers to realize analysis and processing of the model, and can feed back the processing result to the terminal device. The present application will be described in detail through specific embodiments.

[0038] Please refer to Figure 2 , Figure 2 The processing method for electrode particle filling provided by the embodiments of the present application includes the following steps:

[0039] Step S10, a two-dimensional model of the electrode is established based on preset electrode size data.

[0040] The server can receive the electrode size information input by the user on the client, preset two-dimensional size data of the electrode according to the electrode size information, and establish a two-dimensional model of the electrode based on the two-dimensional size data of the electrode. For example, when a developer needs to establish a two-dimensional model of the electrode, the developer can input the size information of the electrode into the client. The server can receive the electrode size information input by the user on the client, and preset two-dimensional size data based on the electrode size information, so as to establish a two-dimensional model of the electrode. In this way, the established model is consistent with the actual electrode, and the accuracy of the particle model is increased.

[0041] It should be understood that the electrode size data herein refers to the length, width or thickness size data of the electrode. The two-dimensional size data of the electrode can be the length data and the thickness data of the electrode, or the width data and the thickness data of the electrode. For example, the developer can input the length and thickness information of a certain electrode in actual production into the client, so that the server establishes a two-dimensional model of the electrode according to the length information and the thickness information. Figure 3 As shown in FIG. 10, step S10, i.e., establishing a two-dimensional model of the electrode based on the preset electrode size data, includes the following steps:

[0042] Step S11, presetting the size data of the electrode, the size data including a length parameter and a thickness parameter.

[0043] Step S12, establishing a two-dimensional model of the electrode based on the length parameter and the thickness parameter.

[0044] For steps S11-S12, in one application scenario, the server can receive the length and thickness information of the electrode input by the user on the client, and set the two-dimensional size data of the electrode according to the received length and thickness information of the electrode. The two-dimensional size data can be the length data and the thickness data of the electrode. Based on the two-dimensional size data of the electrode, the horizontal coordinate axis and the total coordinate axis of the two-dimensional model can be set. Specifically, the server can establish a two-dimensional model having a horizontal coordinate axis and a vertical coordinate axis. The length of the electrode can be set as the length of the horizontal coordinate axis, and the thickness of the electrode can be set as the length of the vertical coordinate axis. For specific application scenarios, the thickness of the electrode can also be set as the length of the horizontal coordinate axis, and the length of the electrode can be set as the length of the vertical coordinate axis.

[0045] If the two-dimensional model of the electrode forms a rectangular region, the length of the horizontal coordinate axis can be the length of the rectangular region, and the length of the vertical coordinate axis can be the width of the rectangular region. The area of the rectangular region is the two-dimensional area of the electrode. For example, the length of the electrode can be represented as L, the thickness of the electrode can be represented as T, and the two-dimensional area of the electrode can be represented as S, so S=L×T.

[0046] Step S20, generating a particle group inside the electrode according to the electrode size data, the particle group including a plurality of particle units aggregated in the particle group.

[0047] Specifically, the two-dimensional size data of different electrodes correspond to different numbers and radii of particles, and the preset two-dimensional size data of the electrode correspond to the corresponding numbers and radii of particles. For example, the two-dimensional size of the electrode can be represented as the length of the electrode being L and the thickness of the electrode being T, the corresponding number of particles can be N, and the radii of the N particles can be R1, R2, R3,..., RN in turn. As shown in the following table, the two-dimensional size data of the electrode corresponds to the corresponding number and radius of particles. Figure 4 As shown in step S20, that is, generating the particle group inside the electrode according to the electrode size data, the particle group aggregates a plurality of particle units, including the following steps:

[0048] Step S21, according to the electrode size data, querying the particle unit data corresponding to the size data in the historical group, wherein the historical group includes a plurality of electrode size data and corresponding particle unit data, and the particle unit data includes a plurality of particle units.

[0049] Step S22, aggregating the particle unit data to generate a particle group.

[0050] For steps S21-S22, the two-dimensional size data of the preset electrode can be represented as the length of the electrode being L and the thickness of the electrode being T. The historical group stores a plurality of different electrode size data and the particle unit data corresponding to each electrode size data. Based on the two-dimensional size data of the electrode, the electrode size data with length L and thickness T in the historical group can be queried, and the particle unit data corresponding to the electrode size data can be obtained.

[0051] It should be noted that aggregating the particle unit data is to aggregate a plurality of particle units, and a particle group can be obtained. Each particle unit includes a particle and radius data of the particle, and the particle group includes a plurality of particles and radius data of each particle.

[0052] Step S30, generating one of the particle units into the two-dimensional model to create a filled area where the particle unit is located, and create the remaining area in the two-dimensional model as an unfilled area.

[0053] It should be noted that when filling the particle units into the rectangular area formed by the two-dimensional model, the filling can be started from a corner of the rectangular area. First, a particle unit is generated into a corner of the rectangular area, and then the filling of other positions of the rectangular area is performed, so that the space of the rectangular area can be fully utilized. After filling the first particle unit, one particle unit in the particle group can be reduced.

[0054] Specifically, the radius of the first filling particle can be set to R, the length of the horizontal axis of the rectangular region can be set to L, and the length of the vertical axis of the rectangular region can be set to T. When the first filling particle is located at a corner of the origin of the coordinate system, its center coordinates can be (R, R). When the first filling particle is located at a corner of the rectangular region and has a tangent point with the vertical axis, its center coordinates can be (R, TR). When the first filling particle is located at a corner of the rectangular region and has a tangent point with the horizontal axis, its center coordinates can be (LR, R). When the first filling particle is located at a corner of the rectangular region and has no tangent points with either the horizontal or vertical axis, its center coordinates can be (LR, TR).

[0055] Step S40: In the remaining particle units, one of the particle units is generated into the unfilled area each time, and the particle unit is moved until a preset state is met. The preset state includes the two sides of the moved particle unit being tangent to the particle units in the filled area, or one side of the moved particle unit being tangent to the particle units in the filled area and the other side being tangent to the boundary of the two-dimensional model, or the two sides of the moved particle unit being tangent to the boundary of the two-dimensional model.

[0056] It should be noted that when filling the unfilled area with the second particle unit in the particle group, the second particle unit can be filled along the axis of the first particle unit, and the second particle unit and the first particle unit can be located at the two corners of the rectangular area.

[0057] It should be noted that the axis of the first particle unit can be either the vertical axis or the horizontal axis. Taking the example of the first particle unit being located in a corner of a rectangular area and having no tangent point with the horizontal or vertical coordinate axis, and the second particle unit filling the horizontal axis direction of the first particle unit, the second particle unit can be filled into the rectangular area so that the second particle unit is located in a corner of the rectangular area and has a tangent point with the vertical coordinate axis.

[0058] Specifically, the first particle unit can be positioned at one corner of a rectangular area, with no tangent point to the horizontal or vertical coordinate axes. The second particle unit is then filled along the horizontal axis of the first particle unit, positioned at one corner of the rectangular area and having a tangent point to the vertical coordinate axis. At this point, the first and second filled particle units are a certain distance apart. The second particle unit can be given a moving speed, causing it to move towards the first particle unit along the horizontal axis to fill it. For example... Figure 5 As shown, in step S40, that is, in the remaining particle units, one of the particle units is generated into the unfilled area each time, and the particle unit is moved until a preset state is met, including the following steps:

[0059] Step S41, based on the distance data of the particle unit in the unfilled area and the particle unit in the filled area, setting the moving speed of the particle unit in the unfilled area;

[0060] Step S42, when the particle unit in the unfilled area moves to meet the preset state, stopping moving the particle unit.

[0061] For steps S41-S42, taking filling the second particle unit as an example, the second particle unit can be given a moving speed to move along the horizontal axis direction. The moving speed of the second particle unit can be set as V, and the closest distance between the second particle unit and the particle unit in the filled area can be set as D. When the value of the distance D decreases, the value of the moving speed V can correspondingly decrease. When the second particle unit moves at variable speed, the particle unit can more efficiently move to be tangent to the particle unit in the filled area, thereby improving the filling speed of the particle unit.

[0062] Specifically, the relationship between the moving speed and the closest distance can be a linear relationship or a nonlinear relationship. Taking the linear relationship between the moving speed V and the closest distance D as an example, V=KD+B, where K is a constant and B is a constant.

[0063] It should be noted that when the second particle unit has a tangent point with the particle in the filled area, i.e., is tangent to the particle, the second particle unit stops moving. At this time, the area where the second particle unit is located is added to the filled area, so that the area of the filled area is expanded. When there is no tangent point, i.e., is not tangent, the second particle unit continues to move until the second particle unit has a tangent point with the particle in the filled area, and then the second particle unit stops moving. As shown in FIG. 4, after step S42, i.e., after the step of stopping moving the particle unit when the particle unit in the unfilled area moves to meet the preset state, the following steps are included: Figure 5

[0064] Step S43, judging whether the area value of the unfilled area is less than the minimum area value of the remaining particle units;

[0065] Step S44, when the minimum area value is not less than the minimum area value, continuing to generate the particle unit into the unfilled area;

[0066] Step S45, when the minimum area value is less than the minimum area value, stopping generating the particle unit into the unfilled area.

[0067] For steps S43-S45, after filling the second particle unit, one particle unit in the particle group can be reduced. The area of the filled area increases, and the area of the unfilled area decreases. Then the particle units in the particle group can be continuously taken out and filled into the unfilled area in turn.​

[0068] For example, the first filling particle unit can be positioned at a corner of a rectangular area and has no tangency point with the horizontal or vertical coordinate axes. The second particle unit can be filled along the horizontal axis of the first filling particle unit, also positioned at a corner of the rectangular area and having a tangency point with the vertical coordinate axis. If the remaining space along the horizontal axis of the first particle unit is greater than the area of ​​any particle unit in the particle group, a third particle unit can be taken from the particle group and filled along the horizontal axis of the first particle unit, also positioned at a corner of the rectangular area and having a tangency point with the vertical coordinate axis. Similarly, the third particle unit can be given a variable moving speed to move along the horizontal axis. When the third filling particle unit is tangent to the second particle unit in the filling area, the movement of that particle unit stops. At this point, the area where the third particle unit is located is added to the filling area, expanding the filling area. Simultaneously, one of that particle unit is removed from the particle group. If the remaining space along the horizontal axis of the first particle unit is greater than the area of ​​any particle unit in the particle group, particle units can be repeatedly filled along that horizontal axis until the horizontal axis is filled with particle units.

[0069] It's important to note that after the first particle unit is filled along its horizontal axis, if there is remaining space in the top center of the rectangular area that can be filled by a single particle unit from the particle group, another particle unit from the particle group can be added to fill the top center of the rectangular area. Similarly, this particle unit is given a variable speed, allowing it to move along either the horizontal or vertical axis. Movement of this particle unit stops when both sides of it are tangent to particles in the filling area, or when both sides of it are tangent to the four sides of the rectangular area, or when one side of it is tangent to a particle in the filling area and the other side is tangent to the four sides of the rectangular area. At this point, the area where this particle unit was located is added to the filling area, expanding the filling area. Simultaneously, one particle unit from the particle group is removed.

[0070] It should be further explained that if there is still remaining area in the top center of the rectangular region that can be filled with a single particle unit from the particle group, particle units from the particle group can be repeatedly removed and used to continue filling until the area of ​​the unfilled area is smaller than the area of ​​the smallest particle unit, or when all particle units in the particle group are used up, filling stops. For example, Figure 6 As shown, step S43, namely determining whether the area value of the unfilled area is less than the minimum area value of the remaining particle units, includes the following steps:

[0071] Step S431: Based on the area data of the particle units in the two-dimensional model and the electrode size data, calculate the area value of the unfilled area and the minimum area value of the remaining particle units;

[0072] Step S432, judging whether the area value of the unfilled region is less than the minimum area value of the remaining particle units.

[0073] For steps S431-S432, it is noted that when the area value of the unfilled region is greater than or equal to the area value of the smallest particle unit in the particle group, a particle unit less than or equal to the area of the unfilled region can be randomly taken out from the particle group and filled into the unfilled region.

[0074] It is noted that when the area of the unfilled region gradually decreases until the area is less than the area of the smallest particle unit in the particle group, the filling can be stopped. Alternatively, when the number of particle units in the particle group gradually decreases until the particle units in the particle group are used up, the filling can be stopped.

[0075] It is noted that the area of the unfilled region can be set as S3, the area of the filled region can be set as S2, and the area of the rectangular region can be set as S1. When N particles are filled in the filled region, the radius of each particle in the filled region can be set as R1, R2, R3,..., RN. The area of each particle can be πR1 2 , πR2 2 , πR3 2 ,..., πRN 2 , respectively. Then the area S2 of the filled region is π(R1 2 + R2 2 + R3 2 +..., + RN 2 ), and the area S3 of the unfilled region is S1—(R1 2 + R2 2 + R3 2 +..., + RN 2 ). Wherein, the area S1 of the rectangular region is L×T, L can be the horizontal coordinate length of the rectangular region, i.e. the length of the electrode. T can be the vertical coordinate length of the rectangular region, i.e. the thickness of the electrode.

[0076] Step S50, obtaining the feature data of each particle unit in the two-dimensional model, the feature data including area data and coordinate data.

[0077] It is noted that the radius of each particle unit in the filled region can be set as R1, R2, R3,..., RN. The area of each particle can be πR1 2 , πR2 2 , πR3 2 ,..., πRN 2 , respectively.

[0078] The coordinate data of each particle unit can be the center coordinate data of each particle unit, by which the distribution position of each particle unit in the two-dimensional model can be determined. For example, the radius of one particle unit can be set as 1, and the center coordinate of the particle unit in the two-dimensional model can be set as (X, Y). When the center coordinate of the particle unit is set as (2, 30), the coordinate data (2, 30) of the particle unit can be obtained.

[0079] In step S60, the porosity of the electrode is calculated based on the feature data and the electrode size data.

[0080] When the porosity of the electrode is calculated, the required feature data can be the radius data of each particle unit. The sum of the areas of all particle units can be calculated based on the radius data. Meanwhile, the area of the rectangular region can be calculated based on the electrode size data. Since the porosity of the electrode is the ratio of the area of the unfilled region to the area of the rectangular region, the porosity of the electrode can be obtained. As shown in the following formula, in step S60, i.e., the porosity of the electrode is calculated based on the feature data and the electrode size data, the following steps are included. Figure 6

[0081] In step S61, the porosity of the electrode is calculated based on the area data of the particle units in the two-dimensional model and the electrode size data.

[0082] In step S62, the tortuosity of the electrode is calculated based on the coordinate data of the particle units in the two-dimensional model and the electrode size data.

[0083] For steps S61-S62, the area of the rectangular region can be set as S1, the horizontal coordinate length of the rectangular region can be set as L, and the vertical coordinate length of the rectangular region can be set as T, so S1=L×T. The horizontal coordinate length of the rectangular region is the length of the electrode, and the vertical coordinate length of the rectangular region is the thickness of the electrode. Specifically, the area of the unfilled region can be set as S3, the area of the filled region can be set as S2, and the radius of each particle unit in the filled region can be set as R1, R2, R3,..., RN. The area of each particle unit can be πR1 2 , πR2 2 , πR3 2 ,..., and πRN 2 , respectively. Then, the area S2 of the filled region is π(R1 2 +R2 2 +R3 2 +..., and the area S3 of the unfilled region is S1— π(R1 2 +R2 2 +R3 2 +..., where S1 is the area of the rectangular region. 2 2 ​​Since the porosity of the electrode is the ratio of the area of ​​the unfilled region to the area of ​​the rectangular region, the porosity of the electrode can be set as N = S3 / S1.

[0084] It should be noted that the tortuosity of the electrode is the ratio of the length of the curve 70 passing through the pores between the particles to the length of the shortest straight line 80 passing through the particles. When calculating the length of the curve 70 passing through the pores between the particles, the curve 70 can be divided into multiple segments, with the straight line connecting the endpoints of each segment replacing the curve 70. Based on the coordinates of each particle, the length of each straight line segment can be calculated, thus obtaining the length of the curve 70. Alternatively, the length of the curve 70 can be obtained through other calculation methods. The length of the shortest straight line 80 passing through the particles can be the length of a rectangular region.

[0085] It is evident that, in the above scheme, this filling method can improve the filling speed of particles and the calculation speed of the model.

[0086] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
