The formation testing process requires continuous charging and discharging of the lithium battery, and the temperature needs to be maintained at 45℃ to achieve optimal lithium-ion activity. With the rapid development of the lithium battery industry, its scale and volume are growing exponentially, and the number of blade-type lithium-ion battery production lines is increasing daily. Traditional formation testing equipment cannot stably maintain the temperature during charging and activation, failing to meet the process requirements of battery manufacturers for blade-type lithium-ion battery production lines, resulting in insufficient production efficiency and energy utilization. Summary of the Invention
[0003] To address the aforementioned issues, this utility model proposes an integrated hydrothermal formation machine. Its design concept involves installing a side air duct and a hydrothermal plate assembly within the formation test hangar, enabling high-speed air circulation within the hangar. This, in turn, ensures stable temperature of the formation equipment and the battery, thereby improving the efficiency of the formation test.
[0004] The hydrothermal synthesis integrated machine includes a rectangular hangar. The top plate of the hangar is equipped with a downward-facing positive electrode needle plate assembly 5, a suction rod assembly 7, and a lifting cylinder 4, which can be pushed up and down. The bottom of the hangar is equipped with a mechanism base frame 47, on which a negative electrode needle plate assembly 6 is provided, corresponding vertically to the positive electrode needle plate assembly 5. The lifting cylinder 4 is connected to the mechanism base frame. The top plate of the hangar is connected to the mechanism base frame 47 via a guide column 41, on which a mechanism middle frame 42 passes. The top of the mechanism middle frame 42 is equipped with a battery tray 44 for accommodating batteries. The bottom of the hangar is supported by a vertical lower limit column 43, so that the horizontal height of the mechanism middle frame 42 is higher than that of the negative electrode needle plate assembly 6.
[0005] The bottom of the middle frame 42 of the mechanism is provided with an upper limit post 45, and the top of the bottom frame 47 of the mechanism is provided with a spring assembly 46. The positions of the upper limit post 45 and the spring assembly 46 are corresponding vertically.
[0006] The hangar has vertical side air ducts 9 on its left and right sides respectively, and the side of the two side air ducts 9 closest to each other is defined as the inner side; the top of the inner side of the side air duct 9 is equipped with an upper fan assembly 2, which can pump air into the hangar from the side air duct 9; the middle of the side air duct 9 is equipped with a water heating plate assembly 3 to regulate the air temperature, and the bottom of the inner side of the side air duct 9 is equipped with a bottom fan assembly 1, which can pump air into the side air duct 9 from inside the hangar; an energy storage explosion relief fan 10 is installed on the upper part of the side air duct 9, which can pump external cold air into the side air duct 9.
[0007] More specifically, the upper fan assembly 2 includes an upper fan mounting plate 22, on which a plurality of upper fans 21 are provided; an upper fan handle 23 is provided at the end of the upper fan mounting plate 22; the side air duct 9 can be pulled out of the upper fan mounting plate 22 through the upper fan handle 23 for easy maintenance.

[0011] The working process of this utility model includes:
[0012] 1. The lifting cylinder 4 pulls the bottom frame 47 of the mechanism to rise, and the spring assembly 46 contacts the upper limit post 45. At this time, the negative electrode plate assembly 6 does not contact the negative electrode tab of the battery.
[0013] 2. The bottom frame 47 and the middle frame 42 of the mechanism move upward together until the positive electrode plate assembly 5 contacts the positive electrode tab of the battery.
[0014] 3. The frame 42 of the mechanism stops moving, but the lifting cylinder 4 is pulled up, and the spring assembly 46 is compressed until the negative electrode tab of the battery contacts the negative electrode needle plate assembly 6. The tray 44 is connected to the suction rod assembly 7. The positive electrode needle plate assembly 5 and the negative electrode needle plate assembly 6 charge and discharge the blade battery, and remove impurities from the electrolyte through the suction rod assembly 7, completing the formation.
[0015] During operation, the upper fan assembly 2 and the bottom fan assembly 1 are turned on. Air inside the hangar is blown into the side air duct 9 by the upper fan assembly 2, and after passing through the air guide plate 8, the temperature is controlled at the hydrothermal plate assembly 3. The bottom fan assembly 1 blows the temperature-controlled air back into the hangar, flowing sequentially through the negative electrode needle plate assembly 6, the battery tray 4, and the positive electrode needle plate assembly 5, and finally being blown back into the side air duct 9 by the upper fan assembly 2.

The top of the mechanism middle frame 42 is equipped with a battery tray 44 for accommodating batteries. The bottom of the hangar is supported by a vertical lower limit column 43, so that the horizontal height of the mechanism middle frame 42 is higher than that of the negative electrode needle plate assembly 6.
[0029] The bottom of the middle frame 42 of the mechanism is provided with an upper limit post 45, and the top of the bottom frame 47 of the mechanism is provided with a spring assembly 46. The positions of the upper limit post 45 and the spring assembly 46 are corresponding vertically.
[0030] The hangar has vertical side air ducts 9 on its left and right sides respectively, and the side of the two side air ducts 9 closest to each other is defined as the inner side; the top of the inner side of the side air duct 9 is equipped with an upper fan assembly 2, which can pump air into the hangar from the side air duct 9; the middle of the side air duct 9 is equipped with a water heating plate assembly 3 to regulate the air temperature, and the bottom of the inner side of the side air duct 9 is equipped with a bottom fan assembly 1, which can pump air into the side air duct 9 from inside the hangar; an energy storage explosion relief fan 10 is installed on the upper part of the side air duct 9, which can pump external cold air into the side air duct 9.

[0033] In some embodiments, the energy storage explosion relief fan 10 can be disassembled together with the front wall of the side air duct 9 for easy maintenance.
[0034] In some embodiments, the side air duct 9 is provided with an air guide plate 8 that connects the upper fan assembly 2 and the bottom fan assembly 1.
[0035] The working process of this utility model includes:
[0036] 1. The lifting cylinder 4 pulls the bottom frame 47 of the mechanism to rise, and the spring assembly 46 contacts the upper limit post 45. At this time, the negative electrode plate assembly 6 does not contact the negative electrode tab of the battery.
[0037] 2. The bottom frame 47 and the middle frame 42 of the mechanism move upward together until the positive electrode plate assembly 5 contacts the positive electrode tab of the battery.
[0038] 3.

[0040] When the temperature exceeds the maximum set temperature threshold, the hydrothermal plate assembly 3 stops working. The energy storage explosion relief fan 10 starts, pumping the cooler air from outside the hangar into the side air duct 9, and then circulating the cool air into the hangar through the upper fan assembly 2 and the bottom fan assembly 1, thereby achieving the purpose of cooling.
[0041] When the thermal runaway in the hangar becomes extremely severe and the air pressure rises sharply, the energy storage explosion relief fan 10 will be activated, and the auxiliary explosion-proof valve will release pressure together to prevent an explosion.
