[0002] The aspect ratio of graphite plays an important role in practical applications. A large aspect ratio usually means better electrical conductivity and heat transfer because the electrical conductivity and heat transfer of graphite are related to its surface area.

Therefore, in different applications, it is necessary to determine the aspect ratio of graphite according to specific requirements and characteristics. For example, when manufacturing electrodes, the electrical conductivity of graphite needs to be considered, and a larger aspect ratio is usually used to enhance the electrical conductivity of the electrodes; while in the machining of graphite, the smoothness of the graphite surface needs to be considered, and a smaller aspect ratio is usually used to make it more compact.

[0022] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the present application pertain. The terms (such as those defined in a commonly used dictionary) will be interpreted as having the same meaning as their contextual meaning in the relevant technical field and will not be interpreted as having an idealized or overly formal meaning unless clearly defined in various embodiments of the present application.

[0023] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0024] Refer to Figure 1 , Figure 1 which is a schematic structural diagram of a graphite aspect ratio measurement system provided for this embodiment. The measurement system mainly includes: a display screen 100, a control device 200, a positive ion generating device 300, a conductive plate 400, a sample cell 500, a metal plate 600, a drainage pipeline 700, an electric valve 800, a vibration device frequency regulator 900, a vibration device 1000, a refrigeration device 1100, a handle flip cover 1200, and a box body 1300.

[0025] Among them, the display screen 100 is connected to the control device 200, the control device 200 is connected to the positive ion generating device 300, the positive ion generating device 300 is connected to the conductive plate 400, the conductive plate 400 is connected to the metal plate 600, the metal plate 600 is connected to the sample cell 500, the sample cell 500 is connected to the drainage pipeline 700, the drainage pipeline 700 is connected to the electric valve 800, the control device 200 is also connected to the vibration device frequency regulator 900, the vibration device frequency regulator 900 is connected to the vibration device 1000, and the control device 200 is also connected to the electric valve 800 and the refrigeration device 1100 for controlling the electric valve 800 and the refrigeration device 1100. The sample cell 500, the conductive plate 400, the metal plate 600, etc. are arranged inside the box body 1300. A handle flip cover 1200 is arranged on one side of the box body 1300, and the handle flip cover 1200 can be opened for putting a sample into the sample cell 500. The metal plate 600 can be a copper plate or made of other metals.

[0026] The number of vibration devices 1000 can be multiple, and Figure 1 exemplarily, one vibration device 1000 is respectively arranged at the four corners of the box body 1300. The refrigeration device 1100 is fixedly arranged on the box body 1300 and is arranged opposite to the metal plate 600. The refrigeration device 1100 is used to spray cold air onto the metal plate 600 to cool the metal plate 600 so that the graphite sample adsorbed on the metal plate 600 freezes.

[0027] The aspect ratio of graphite is the ratio of the radial size to the thickness of the graphite sheet. When testing the aspect ratio of graphite, first, a certain amount of graphite sample and solution need to be placed into the sample cell 500. The solution can be an NaCl solution or other solutions, and the solution needs to cover the surface of the graphite sample. Broken bonds are easily formed at the graphite end face, and thus it is easily oxidized and negatively charged.

[0028] After the graphite sample and the solution are fully mixed, then turn on the positive ion generating device 300 to generate positive ions through the positive ion generating device 300, and attach the positive ions to the metal plate 600 through the conductive plate 400. Since the graphite end face is negatively charged, it will be adsorbed by the metal plate 600 with positive ions attached, so that the graphite cross-section is adsorbed and fixed on the metal plate 600. Then turn on the freezing device 1100 to freeze and fix the graphite sample adsorbed on the metal plate 600, thereby obtaining a frozen sample. Then take out the frozen sample, and the aspect ratio of the graphite sample in the frozen sample can be measured by a measuring device. The measuring device can be a scanning electron microscope or other measuring equipment. The frozen sample after freezing is photographed by the scanning electron microscope, and then the aspect ratio of the sample is obtained. The measuring device can be connected to the sample cell for directly measuring the frozen sample, or it can not be connected to the sample cell. After the frozen sample is generated, the frozen sample is transferred to the measuring device for measurement.

[0029] In this embodiment, broken bonds are easily formed at the graphite end face, and thus it is easily oxidized and negatively charged. The positive ion generating device 300 is used to generate opposite charges, so that the graphite end face is adsorbed on the metal plate 600 to form a three-dimensional distribution. Then the required sample is obtained by freezing and fixing for scanning electron microscope photography. This avoids the problem that when calculating the aspect ratio of graphite by the electron microscope method, since graphite is a layered mineral and is easily spread on the surface of the sample cell 500, it is difficult to photograph the thickness of graphite. The measurement principle of this embodiment is simple and the accuracy of the measurement result is higher.

[0030] In one embodiment, the display screen 100 is configured to receive the first operating parameter and the second operating parameter, and send the first operating parameter and the second operating parameter to the control device 200; The control device 200 is configured to control the operation of the positive ion generating device 300 according to the first operating parameter, and control the operation of the freezing device 1100 according to the second operating parameter.

[0031] Specifically, the corresponding parameters can be set first through the display screen 100, such as setting the positive ion generation intensity I of the positive ion generating device 300, the frequency F of the vibration device frequency regulator 900, and the freezing temperature T of the freezing device 1100, and then sending these data to the control device 200.

[0032] The control device 200 can be a device such as a PLC or a microprocessing unit. A programmable logic controller (PLC) is a digital computing operation electronic system specifically designed for application in an industrial environment. It uses a programmable memory to store instructions for performing operations such as logical operations, sequential control, timing, counting, and arithmetic operations internally, and controls various types of mechanical equipment or production processes through digital or analog inputs and outputs.

[0033] The control device 200 can control the positive ion generation intensity of the positive ion generation device 300, the frequency of the vibration device frequency regulator 900, and the refrigeration temperature of the refrigeration device 1100 according to preset parameters.

[0034] In this embodiment, the display screen 100 receives the parameters of each device and sends the parameters to the control device, so that the control device can automatically control the measurement process according to the parameters, improving the measurement efficiency.

[0035] In one implementation, the display screen 100 is further configured to receive a third operating parameter and send the third operating parameter to the control device 200; The control device 200 is configured to send an adjustment signal to the vibration device frequency regulator 900 according to the third operating parameter, so that the vibration device frequency regulator 900 generates a corresponding vibration signal according to the adjustment signal; The vibration device 1000 is configured to vibrate according to the vibration signal.

[0036] The vibration device 1000 is mainly used to vibrate the graphite sample and the solution in the sample cell 500, so that the graphite sample and the solution are fully fused, avoiding the accumulation of graphite samples and causing difficulties in measurement. The parameters of the vibration device frequency regulator 900 can include, in addition to the vibration frequency, the vibration duration. When the vibration duration is less than the preset vibration duration, the control device 200 controls the vibration device frequency regulator 900 to continue working, so that the vibration device 1000 continues to vibrate the sample cell 500. If the vibration duration is greater than or equal to the preset vibration duration, the control device 200 controls the vibration device frequency regulator 900 to stop working for subsequent measurement work.

[0037] In this embodiment, by setting the third operating parameter of the vibration device frequency regulator 900, the vibration device frequency regulator 900 operates according to the preset parameters, and further enables the vibration device 1000 to vibrate the graphite sample and the solution in the sample cell 500 sufficiently, reducing the measurement difficulty.

[0038] In one embodiment, the control device 200 is further configured to obtain the working duration of the vibration device frequency regulator 900, and determine whether the working duration is greater than or equal to a preset working duration; If it is greater than or equal to the preset working duration, the vibration device frequency regulator 900 is turned off, and the positive ion generation device 300 is controlled to be turned on.

[0039] When the graphite sample is added to the sample cell 500, it may stack together. Therefore, a solution needs to be added to the sample cell 500, and then the graphite sample and the solution in the sample cell 500 are vibrated by the vibration device 1000. To ensure uniform distribution of the graphite sample, the preset working duration of the vibration device frequency regulator 900 can be set, and after the working duration of the vibration device frequency regulator 900 reaches the preset working duration, the vibration device frequency regulator 900 is turned off.

[0040] In this embodiment, by setting the working duration of the vibration device frequency regulator 900, the vibration device 1000 can fully stir and mix the graphite sample in the sample cell 500, improving the measurement accuracy of the subsequent measurement of the graphite aspect ratio.

[0041] In one embodiment, the drain pipe 700 is provided at the bottom of the sample cell 500, the electric valve 800 is provided on the drain pipe 700, the electric valve 800 is connected to the control device 200, and the control device 200 is further configured to: Obtain the opening duration of the positive ion generation device 300, and determine whether the opening duration is greater than or equal to a first preset opening duration; If it is greater than or equal to the first preset opening duration, the positive ion generation device 300 is turned off, and the electric valve 800 is opened. The drain pipe 700 is controlled to be opened through the electric valve 800, so that the remaining graphite sample and the solution in the sample cell 500 are discharged through the drain pipe 700.

[0042] Specifically, since it takes a certain amount of time for the metal plate 600 to adsorb the graphite sample, the positive ion generation device 300 also needs to be turned on for a preset duration. Otherwise, it may cause the metal plate 600 to fail to adsorb enough graphite samples. When the opening duration of the positive ion generation device 300 reaches the first preset duration, the positive ion generation device 300 can be turned off, and the electric valve 800 can be opened, so that the remaining graphite sample and the solution that have not been adsorbed in the sample cell 500 flow out of the sample cell 500 along the drain pipe 700.

[0043] In this embodiment, by setting the opening duration of the positive ion generating device 300 such that the opening duration of the positive ion generating device 300 meets a first preset duration, the metal plate 600 can adsorb sufficient graphite samples, so that the aspect ratio of the thickness to diameter of multiple graphite samples can be measured at one time.

[0044] In one implementation, the control device 200 is further configured to: Obtain the opening duration of the electric valve 800 and determine whether the opening duration is greater than or equal to a second preset opening duration; If it is greater than or equal to the second preset opening duration, control the electric valve 800 to close and turn on the refrigeration device 1100.

[0045] Specifically, after the electric valve 800 is opened for the second preset opening duration, it can be determined that the residual graphite samples and the solution in the sample cell 500 have been emptied. At this time, the refrigeration device 1100 can be turned on to freeze the graphite samples adsorbed on the metal plate 600 to obtain frozen samples.

[0046] In this embodiment, after the electric valve 800 is opened for a preset duration, the residual graphite samples and the solution in the sample cell 500 are emptied, and then the graphite samples adsorbed on the metal plate 600 are frozen, avoiding the solution and the residual graphite samples in the sample cell 500 from being frozen, which may cause damage to the sample cell 500 or be unfavorable for cleaning the sample cell 500.

[0047] Refer to Figure 2 , this embodiment also provides a method for measuring the aspect ratio of the thickness to diameter of graphite, including: S201. Place graphite samples and a solution into the sample cell, oxidize the graphite samples, and make the graphite samples carry negative charges.
