[0030] like Figure 1 Or 2 shows an in-situ infrared battery test cell used in conjunction with infrared, which includes an upper current collector assembly 100, which is integrated into a lower current collector assembly 200 and fixed by a cover plate 1.

[0031] The lower end of the lower current collector assembly 200 is installed in contact with the upper surface of the infrared base plate 400 through the conductive sheet 300. A crystal assembly 500 is provided at the lower end of the infrared base plate 400. The crystal assembly 500 includes a crystal 510 in contact with the lower surface of the infrared base plate 400. The crystal 510 is a zinc selenide crystal, a germanium crystal or a calcium fluoride crystal.

[0032] The crystal base 520 is used to support and fix the crystal 510 . The crystal base 520 is provided with a plurality of fasteners 530 arranged outside the crystal 510 .

[0033] The upper current collecting assembly 100 includes an upper current collecting tank body 110, in which a first conductive metal body 120 is provided through the upper current collecting tank body 110, and a conductive metal block 120 is provided below the upper current collecting tank body 110. The conductive metal block 120 is fixed to the upper current collecting tank body 110 by a first conductive metal body 130. The first conductive metal body 130 is a first conductive metal column arranged in the upper current collecting tank body 110 through a pressure ring 131 and a first seal 132 and extending upward.

[0034] Specifically, the conductive metal block 120 is disposed below the upper current collecting tank body 110 through the second sealing member 121 .

[0035] An insulating sleeve 700 for mounting the battery material 600 is provided below the conductive metal block 120 , and the battery material 600 for testing is sheathed in the insulating sleeve 700 .

[0036] Then, the upper current collector assembly 100 and the insulating sleeve 700 with the battery material 600 fixed thereon are integrally installed in the lower current collecting tank body 210 of the lower current collector assembly 200;

[0037] A second conductive metal body 220 for detecting the lower surface of the battery material 600 is disposed in the lower current collecting tank body 210. The second conductive metal body 220 is a second conductive metal column.

[0038] The lower end of the lower current collector assembly 200 is mounted in contact with the upper surface of the infrared base plate 400 via the third sealing member 230 and the conductive sheet 300 .

[0039] Because of the above structure, the working principle of the utility model is:

[0040] 1. The infrared base plate and the crystal base are fixed with fasteners such as screws, and the crystal is placed on the crystal base;

[0041] 2. A third seal is provided between the lower current collector and the infrared base plate. A conductive sheet is placed in the third seal and fixed with screws.

[0042] 3. Place the insulating sleeve into the cell body of the lower current collector;

[0043] 4. Place the battery material into the insulating sleeve;

[0044] 5. Fix the upper current collecting tank body and the conductive metal block with a first conductive metal body, and seal the upper current collecting tank body and the conductive metal block with a second sealing member;

[0045] 6. Place the upper collecting tank into the lower collecting tank;

[0046] 7. Install the pressure ring and the first seal on the upper manifold body in sequence;

[0047] 8. Then fix it on the top with a cover plate, which has threads inside;

[0048] 9. Finally, fix the cover and the pressure ring with screws.

[0049] Combined with the above structure, the upper current collector and the lower current collector replace the battery shell of the button battery. The upper current collector contacts the negative electrode and serves as the negative electrode wire. The lower current collector contacts the positive electrode and serves as the positive electrode wire.

[0050] When used in conjunction with infrared, it is necessary to refract infrared light through the crystal onto the material and then reflect it out.

[0051] The infrared light itself is direct, and it will use an optical path accessory to change the angle of the incident light so that it can be refracted onto the material.

[0052] This utility model has good sealing performance, which can prevent the electrolyte inside the battery from leaking, ensuring the safety and accuracy of the test. The test cell is easy to operate, and the electrodes can be quickly installed and removed, improving test efficiency. The setting of the infrared base plate can realize real-time monitoring of the chemical changes of the battery during the charging and discharging process, providing a powerful means for studying the performance and reaction mechanism of the battery. Through a more integrated structural design, the in-situ infrared battery test cell combined with infrared is simple to operate and has improved sealing performance. It can monitor the chemical changes of the battery in real time during the charging and discharging process.
