Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery production equipment, in particular to a chemical warehouse. Background Art
[0002] During the production process of batteries, after the batteries are filled with liquid and left to stand, they generally need to be charged, i.e., subjected to formation treatment, so that the electrode materials in the battery react chemically with the electrolyte at the solid-liquid interface, thereby forming a passivation film covering the surface of the electrode materials. This passivation film is called a "solid electrolyte interface" (SEI film for short).
[0003] The existing formation library for forming batteries generally includes a formation unit, which includes a formation cavity. The formation cavity has a placement cavity, and the bottom and top of the placement cavity are respectively provided with a lower charging probe and an upper charging probe. When forming the battery, the battery is first placed in a formation capsule. At this time, the negative pole and the positive pole of the battery are respectively electrically connected to the negative formation probe and the positive formation probe of the formation capsule. The negative formation probe is electrically connected to the negative electrode terminal of the formation capsule, and the positive formation probe is electrically connected to the positive electrode terminal of the formation capsule. The liquid injection port of the battery is matched with the lower end of the hollow gas-tight rod of the formation capsule, so that the interior of the gas-tight rod is connected to the interior of the battery, and the interior of the gas-tight rod is connected to the external environment. Then the formation capsule and the battery in the formation capsule are placed in the placement cavity, and the lower charging probe is connected to the negative electrode terminal of the formation capsule. The upper charging probe is connected to the positive terminal of the formation capsule, so that the lower charging probe is electrically connected to the negative terminal, and the upper charging probe is electrically connected to the positive terminal. Then the lower charging probe and the upper charging probe are connected to the charging power supply respectively, so that the battery can be charged through the charging power supply via the negative terminal and the negative formation probe, the positive terminal and the positive formation probe, so that the battery is subjected to the formation treatment. During the battery formation process, the gas generated when the electrode material inside the battery reacts with the electrolyte at the solid-liquid two-phase interface can be discharged to the external environment through the gas-tight rod of the formation capsule. In this structure, the gas generated by the battery formation is usually discharged relatively slowly, which leads to a relatively long production cycle and reduces production efficiency.

The formation capsule 503 includes: firstly, the buckle cup 5032 of the formation capsule 503 is removed from the top of the lower cavity 5031 of the formation capsule 503, and then the battery 501 is placed in the first inner cavity of the lower cavity 5031. At this time, the battery 501 partially protrudes from the top of the lower cavity 5031, and the negative electrode of the battery 501 is electrically connected to the negative formation probe 5039, as shown in FIG. Fig.12 As shown, the buckle cup 5032 is then covered on the top of the lower cavity 5031 of the formation capsule 503. At this time, the portion of the battery 501 protruding from the top of the lower cavity 5031 is located in the first installation cavity of the buckle cup 5032. The lower end of the airtight rod 5035 cooperates with the injection port 5011 of the battery 501, so that the interior of the airtight rod 5035 is connected to the interior of the battery 501, and the positive electrode of the battery 501 is electrically connected to the positive formation probe 5037. Fig.12As shown, the battery 501 is placed in the formation capsule 503.
[0053] Then, the formation capsule 503 and the battery 501 in the formation capsule 503 are transported to the placement chamber 21 by a stacker and placed at the bottom of the placement groove 221, and the upper end of the lower power-on probe 31 is docked with the corresponding negative electrode probe 50311 of the formation capsule 503, the upper end of the lower charging probe 41 is docked with the negative electrode terminal 5038 of the formation capsule 503, and the end of the lower positioning pin 50 is matched with the corresponding lower positioning groove 50312, so that the upper end of the lower power-on probe 31 is electrically connected to the corresponding negative electrode probe 50311, and the upper end of the lower charging probe 41 is electrically connected to the negative electrode terminal 5038. Then, the second mounting plate 62 is driven downward by the lifting cylinder 63, thereby driving the upper power-on probe 71, the upper charging probe 81, the liquid storage cup 65, and the upper positioning pin 68 to move downward, until the lower end of the upper power-on probe 71 is docked with the corresponding positive electrode probe 5036 of the formation capsule 503, the lower end of the upper charging probe 81 is docked with the upper terminal 5034 of the formation capsule 503, the bottom end of the liquid storage cup 65 is inserted into the upper end of the gas-tight rod 5035 of the formation capsule 503, and the end of the upper positioning pin 68 is matched with the corresponding upper positioning groove 5041. In this way, the power supply can realize the emission of the formation capsule 503 through the lower power-on probe 31 and the negative electrode probe 50311, the upper power-on probe 71 and the positive electrode probe 5036. The hot plate is electrically connected, so that the heating plate can be powered on. After the heating plate is powered on, it generates heat, so that the battery 501 in the formation capsule 503 can be heated. At the same time, the charging power supply can be electrically connected to the negative electrode of the battery 501 through the lower charging probe 41, the negative electrode terminal 5038, and the negative polarization formation probe 5039, and can be electrically connected to the positive electrode of the battery 501 through the upper charging probe 81, the positive electrode terminal 5034, and the positive polarization formation probe 5037. In this way, the battery 501 can be charged by the charging power supply, so that the electrode material in the battery 501 and the electrolyte react chemically at the solid-liquid two-phase interface, thereby forming a passivation film covering the surface of the electrode material, so that the battery 501 can be formed at high temperature. During the process of charging the battery 501, the inside of the battery 501 is evacuated by the vacuum device through the liquid storage cup joint 651, the liquid storage cup 65, and the gas-tight rod 5035 of the formation capsule 503, so that the inside of the battery 501 is in a negative pressure state, so that the gas generated by the formation of the battery 501 can be quickly discharged from the battery 501. The charging time of the battery 501 is, for example, 20 hours, the vacuum degree inside the battery 501 is, for example, -40Kpa, and the temperature at which the heating plate heats the battery 501 is, for example, 45°C. During the process of evacuating the inside of the battery 501, the electrolyte extracted from the battery 501 can be stored in the liquid storage cup 65. When the inside of the battery 501 returns to normal pressure, the electrolyte in the liquid storage cup 65 can flow back to the inside of the battery 501 through the gas-tight rod 5035, so that the battery core of the battery 501 can be re-infiltrated.
[0054] The utility model can realize electrical connection with the negative terminal 5038 of the formation capsule 503 by setting the lower charging probe 41, and drive the upper charging probe 81 to move downward by the lifting assembly 60, so that the upper charging probe 81 can realize electrical connection with the positive terminal 5034 of the formation capsule 503, so that the battery 501 can be charged by the charging power supply, so that the battery 501 can be formed, and the liquid storage cup 65 can be driven to move downward by the lifting assembly 60, so that the end of the liquid storage cup 65 can be plugged into the formation capsule 5 03's air-tight rod 5035 is inserted into the upper end of the battery 501, thereby the interior of the battery 501 can be evacuated through the vacuum equipment via the liquid storage cup joint 651, the liquid storage cup 65, and the gas-tight rod 5035 of the formation capsule 503, so that the interior of the battery 501 is in a negative pressure state, so that the gas generated by the formation of the battery 501 can be quickly discharged from the battery 501, shortening the production cycle and improving the production efficiency. At the same time, in the process of evacuating the interior of the battery 501, the liquid storage cup 65 can prevent the electrolyte in the battery 501 from being extracted from the battery 501.
