Description

Technical Field

[0001] The invention relates to the technical field of lithium-air battery testing, and in particular to a multi-channel button-type lithium-air battery testing mold. Background Art

[0002] The molds used in most lithium-air battery research can basically be summarized into two categories: classic Swagelok battery molds and commercial lithium-air button battery test tubes. These two molds can basically meet the current research needs of lithium-air batteries to a certain extent, but they both have certain defects. Since the lithium-air battery assembly needs to be carried out in a water-free and oxygen-free glove box, when it is transferred to an oxygen atmosphere, it is necessary to introduce oxygen from the only vent on the top of the Swagelok battery mold to exhaust argon. Since the density of oxygen is lower than that of argon, it is not easy to completely exhaust argon. The actual test is carried out in a mixed atmosphere of oxygen and argon. Although the subsequent work will separate the air inlet and outlet channels, the stainless steel vent pipe is also the positive electrode conductive path. It is necessary to ensure that the vent pipe and the positive electrode are in good contact, but too tight assembly can easily damage the positive electrode or cause a short circuit. In view of the above two points, and the fact that the Swagelok battery mold can only test one battery at a time, the experimental data obtained have poor consistency and repeatability. For this reason, it is necessary to use a battery test mold to perform multi-channel testing operations on button lithium-air batteries.

[0003] After searching, according to the patent network CN 219871418 U, a multi-channel button-type lithium-air battery test mold, the multi-channel button-type lithium-air battery test mold includes: a mold lower seat, which is provided with a cavity; a mold upper seat, which can be installed on the mold lower seat in an openable and closable manner to maintain the cavity in a sealed gas environment when closed with the mold lower seat; a battery fixing device, which is detachably installed in the cavity, and a first groove and a second groove arranged around the first groove are provided in the middle of the battery fixing device; wherein the first groove is suitable for accommodating a button battery seat for connecting the positive and negative electrodes of the button battery, and the second groove is filled with a solvent, so that a solvent environment close to the saturated vapor pressure state is formed in the cavity, so as to suppress the volatilization loss of the solvent in the button battery during the button battery cycle test.

[0004] However, although the existing test mold can perform better multi-channel testing operations on button-type lithium-air batteries when in use, the centering sliding convenience between the battery fixing plates is not high when the test mold is used, which reduces the operating space for installing the button-type lithium-air battery on the battery fixing plate, and after the button-type lithium-air battery is installed on the battery fixing plate and lowered into the test mold, the linkage sealing effect of the test solvent in the solvent tank is not high, so that when the battery fixing plate is lowered into the test mold, there will be shaking, causing leakage of the test solvent, affecting the accuracy of the lithium-air battery test data, and after the battery fixing plate is lowered into the test mold, the linkage sealing effect of the test mold is not high, reducing the convenience of test personnel in using the test mold, and does not meet people's usage needs. For this reason, we propose a multi-channel button-type lithium-air battery test mold. Summary of the invention
