Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1 to Figure 4In an embodiment of the utility model, a lithium battery charging and discharging science demonstration device includes an operating table 6, on which a support plate 61 is installed, and the surface of the support plate 61 is arranged vertically. Two fixing seats 5 are arranged on the front side of the support plate 61, and the two fixing seats 5 and the support plate 61 are fixed to each other through support columns 53. And the length direction of the support column 53 is perpendicular to the surface of the support plate 61. The two fixing seats 5 are arranged symmetrically on the left and right, and the two fixing seats 5 are made of transparent plastic. A first mounting hole is opened on the side surfaces of the two fixing seats 5 opposite to each other. And on the same fixing seat 5, a second arc hole is opened through the side surfaces located on the upper and lower sides of the first mounting hole. The first mounting hole and the second arc hole cooperate with each other to form a three-way pipe structure.

[0038] The two ends of the guide cylinder 1 are coaxially inserted into the two first mounting holes, so that the guide cylinder 1 is fixedly mounted between the two fixing seats 5 .

[0039] Two semi-circular guide tubes 2 are symmetrically arranged on the upper and lower sides of the guide tube 1, and the two ends of the guide tube 2 are respectively inserted into the second arc-shaped holes, so that the two guide tubes 2 are fixedly installed on the two fixing seats 5. The two guide tubes 2 are butt-jointed to form a circular tube body, and the tube cavities of the two guide tubes 2 constitute a circular moving channel for the second simulation ball 21 to move.

[0040] A first simulation ball 11 with a diameter slightly smaller than the inner diameter of the cylinder cavity is installed in the cylinder cavity inside the guide cylinder 1, and the first simulation ball 11 can make reciprocating linear motion in the cylinder cavity. A first guide hole 13 is opened on the outer wall surface of the guide cylinder 1, and the hole length direction of the first guide hole 13 is parallel to the axial direction of the guide cylinder 1. A first guide rod 12 is fixedly installed on the first simulation ball 11. The bottom end of the first guide rod 12 passes through the first guide hole 13 and is connected to the driving end of the first drive assembly 3. The first drive assembly 3 includes two pulleys 31 respectively installed at both ends of the guide cylinder 1, and a first drive motor 32 that is transmission-connected to one of the pulleys 31 and can rotate forward and reverse. A transmission belt 33 is sleeved on the two pulleys 31, and the length direction of the transmission belt 33 extends along the axial direction of the guide cylinder 1. The bottom end of the first guide rod 12 is fixedly installed on the belt surface of the transmission belt 33. Through the forward and reverse rotation of the first drive motor 32, the first simulation ball 11 can be driven to reciprocate between the two ends of the guide cylinder 1, thereby simulating the movement of lithium ions between the positive and negative electrodes of the lithium battery.

[0041] A second simulation ball 21 with a diameter slightly smaller than the inner diameter of the lumen is installed in the lumen of the guide tube 2, and the second simulation ball 21 can make circular circular motion in the annular moving channel. A second guide hole 23 is provided on the outer circumferential surface of the guide tube 2, and the hole length direction of the second guide hole 23 extends along the axial direction of the guide tube 2. The second guide holes 23 on the two guide tubes 2 are matched with each other to form an annular guide hole, and a second guide rod 22 is fixedly installed on the second simulation ball 21. The bottom end of the second guide rod 22 passes through the annular guide hole and is connected to the driving end of the second driving component 4.

[0042] The second driving assembly 4 includes a second driving motor 42, and the axial direction of the second driving motor 42 coincides with the axial direction of the annular guide hole.

[0043] During the charging process of the lithium battery, the first driving motor 32 rotates forward, and the first simulation ball 11 moves from left to right in the guide tube 1 under the traction of the transmission belt 33, to indicate that the lithium ions accumulated at the positive electrode in the real lithium battery are constantly moving to the negative electrode. At the same time, the second driving motor 42 is started, the second swing rod 41 rotates half a circle clockwise, and the second simulation ball 21 moves from left to right in the guide tube 2 under the traction of the second swing rod 41, to indicate that the electrons accumulated at the positive electrode in the real lithium battery are constantly moving to the negative electrode. The first simulation ball 11 and the second simulation ball 21 reach the right end at the same time and touch each other, indicating that the lithium ions and electrons are combined with each other at the negative electrode of the lithium battery.

[0044] During the discharge of the lithium battery, the first driving motor 32 reverses, and the first simulation ball 11 moves from right to left in the guide tube 1, to indicate that the lithium ions accumulated at the negative electrode in the real lithium battery are constantly moving toward the positive electrode. At the same time, the second driving motor 42 continues to operate, and the second swing rod 41 rotates another half circle clockwise, and the second simulation ball 21 moves from right to left in the guide tube 2, to indicate that the electrons accumulated at the negative electrode in the real lithium battery are constantly moving toward the positive electrode. The first simulation ball 11 and the second simulation ball 21 reach the left end at the same time and contact each other, indicating that the lithium ions and electrons are combined with each other at the positive electrode of the lithium battery. It can be seen that the utility model can truly restore the movement process of electrons and lithium ions during the charging and discharging process of the lithium battery, allowing users to understand the principle of the charging and discharging process of the lithium battery.
