Description

A quenching device for solid electrolytes Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a quenching device for solid electrolytes. Background Technology

[0002] All-solid-state batteries, due to their use of non-flammable solid electrolytes instead of liquid electrolytes, are considered a potential solution to the safety issues of traditional lithium-ion batteries. Glassy solid electrolyte materials, in particular, have attracted widespread attention because their ionic conductivity is comparable to that of liquid electrolytes. Compared to crystalline solid electrolytes, glassy solid electrolytes lack crystal channels and isotropic conduction paths, and their lack of grain size and crystallinity helps eliminate grain boundary resistance, further improving their ionic conductivity to the point of being comparable to that of liquid electrolytes.

[0003] Quenching is a key method for obtaining glassy solid electrolytes. The general process of quenching using existing equipment for solid electrolytes is as follows: the solid electrolyte material to be quenched is placed in a heating device (e.g., a tube furnace) and heated to a certain temperature (generally the melting point or softening point). Then, the solid electrolyte is quickly removed from the heating device and placed in a quenching container (usually open) containing a liquid medium such as quenching oil or cold water for rapid cooling. Because the heating device and quenching container in existing solid electrolyte quenching equipment are separate, the solid electrolyte material is exposed to the air when transferred from the heating device to the quenching container, leading to a reaction and decomposition. Furthermore, since existing quenching containers are generally open, removing the quenched solid electrolyte material from the quenching container also exposes it to the air, further exacerbating its decomposition. Summary of the Invention

[0004] The purpose of this invention is to provide a quenching device for solid electrolytes. This quenching device can greatly reduce the probability of materials coming into contact with air during the quenching process. Furthermore, the quenching container of the quenching device can be separated from the furnace tube under sealed conditions, enabling sealed transfer of materials and improving the quenching effect.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model discloses a quenching device for solid electrolytes, including a furnace body, the furnace body including a furnace tube and a furnace chamber, the furnace chamber being located outside the furnace tube and used for heating the furnace tube; a lifting device for lifting a material box is provided at the first end of the furnace tube, and the second end of the furnace tube is open; a quenching container, the quenching container being detachably connected to the second end, the quenching container having a quenching cavity with an opening, the quenching container also having a quenching agent injection port communicating with the quenching cavity; a sealing structure, the sealing structure being connected to the quenching container and located on the side of the opening away from the furnace tube; wherein, when the sealing structure is open, the opening is in communication with the furnace tube, and when the lifting device releases the material box, the material box can fall into the quenching cavity.

[0010] In some embodiments, the furnace tube further includes an inlet pipe and an outlet pipe, the inlet pipe being connected to the furnace tube and the outlet pipe being connected to the furnace tube, the inlet pipe being used to introduce inert gas into the furnace tube and the outlet pipe being used to discharge gas from the furnace tube.

[0011] In some specific embodiments, the air inlet pipe is disposed near the first end, and the air outlet pipe is disposed near the second end.

[0012] In some embodiments, the quenching equipment for solid electrolytes further includes a housing, the housing including a support base and an insulation shell, the insulation shell being connected to the support base and defining an installation cavity, the furnace tube passing through the installation cavity, the furnace chamber being located within the installation cavity, and the first end and the second end of the furnace tube extending out of the installation cavity; the quenching container is mounted on the support base, wherein the installation cavity is filled with a layer of insulation material.

[0013] In some embodiments, the quenching container is provided with a quenching agent injection pipe communicating with the quenching agent injection port, and the quenching agent injection pipe or the quenching agent injection port is provided with a quenching agent injection control valve.

[0014] In some embodiments, the quenching container is further provided with an observation port and an illumination element disposed near the observation port.

[0016] The beneficial effects of this utility model are as follows: In actual operation, the material to be quenched is placed in a material box and then hung on a hoisting device via a hoisting line. The heating element in the furnace is then activated to heat the furnace tube, thereby heating the material to be quenched in the material box. After a certain period of time, when quenching is required, quenching agent is injected into the quenching container through the quenching agent injection port. The quenching agent enables the quenching container to cool rapidly. Then, the sealing structure is opened to connect the opening of the quenching chamber with the furnace tube. The hoisting device releases the material box, allowing it to fall into the quenching chamber under its own weight. The sealing structure is then closed to rapidly cool the solid electrolyte in the material box. After cooling, the quenching container is removed from the second end of the furnace tube and transferred to a protective atmosphere chamber for the next step. The entire quenching and transfer process greatly reduces the chance of contact with air, thus improving the quenching effect.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] This utility model discloses a quenching device for solid electrolytes (hereinafter referred to as the quenching device for ease of description). Referring to Figures 1-3, the quenching device of this embodiment includes a furnace body 100, a quenching container 200, and a sealing structure 300. The furnace body 100 includes a furnace tube 110 and a furnace chamber 120. The furnace chamber 120 is located outside the furnace tube 110 and is used to heat the furnace tube 110. A lifting device 800 for lifting the material box 10 is provided at the first end 111 of the furnace tube 110, and the second end 112 of the furnace tube 110 is open. The quenching container 200 is detachably connected to the second end 112 of the furnace tube 110. The quenching container 200 has a quenching chamber 210 with an opening 211. The quenching container 200 is also provided with a quenching agent injection port that communicates with the quenching chamber 210. The sealing structure 300 is connected to the quenching container 200 and is located on the side of the opening 211 away from the furnace tube 110. When the sealing structure 300 is opened, the opening 211 communicates with the furnace tube 110. When the hoisting device 800 releases the material box 10, the material box 10 can fall into the quenching chamber 210. Understandably, in actual operation, the material to be quenched is placed in the material box 10 and then suspended from the hoisting device 800 via the hoisting line 20. The heating element in the furnace 120 is then activated to heat the furnace tube 110, thereby heating the material to be quenched in the material box 10. After maintaining this temperature for a certain period, when quenching is required, quenching agent is injected into the quenching container 200 through the quenching agent inlet. The quenching agent allows the quenching container 200 to cool rapidly. Then, the sealing structure 300 is opened, opening 211 of the quenching chamber 210. Connected to the furnace tube 110, the hoisting device 800 releases the material box 10, allowing it to fall into the quenching chamber 210 under its own weight. Then, the sealing structure 300 is closed to rapidly cool the solid electrolyte in the material box 10. After cooling, the quenching container 200 is removed from the second end 112 of the furnace tube 110 and transferred to a protective atmosphere chamber for the next step. The entire quenching and transfer process greatly reduces the chance of contact with air and improves the quenching effect.

[0036] Optionally, liquid nitrogen, liquid argon, or dry ice can be selected as the quenching agent, which prevents the material from being contaminated by conventional liquid quenching oil, and the powder can be collected directly. Of course, existing liquid quenching agents such as quenching oil and quenching water can also be selected. The quenching equipment in this embodiment can use not only liquid quenching agents, but also quenching agents such as liquid nitrogen that can be gas quenched, showing high compatibility.

[0037] Optionally, the material in the material box 10 can be Li 10 GeP2S 12 Sulfide solid electrolyte materials, LiAlCl 2.5 O 0.75 Solid electrolyte materials include isohalide solid electrolyte materials and oxide solid electrolyte materials such as Li₂PO₂N. Of course, other solid electrolyte materials can also be selected according to actual needs.

[0038] Optionally, the sealing structure 300 can be a sealing valve or other sealing mechanism that can be opened and closed.

[0039] Referring to Figure 2, the furnace tube 110 also has an inlet pipe 130 and an outlet pipe 140. The inlet pipe 130 is connected to the furnace tube 110, and the outlet pipe 140 is connected to the furnace tube 110. The inlet pipe 130 is used to introduce inert gas into the furnace tube 110, and the outlet pipe 140 is used to exhaust air from the furnace tube 110. It can be understood that before starting to heat the furnace tube 110, inert gas (nitrogen, helium, etc.) can be injected into the furnace tube 110 through the inlet pipe 130, and air is exhausted from the furnace tube 110 through the outlet pipe 240. This ensures that the material box 10 remains within an inert gas atmosphere within the furnace tube 110 during the heating process, preventing the material from contacting air during heating and thus further improving the material's performance.

[0040] Optionally, referring to Figure 2, an inlet valve 150 is provided on the inlet pipe 130, and an outlet valve 160 is provided on the outlet pipe 140. After exhausting, the inlet valve 150 and the outlet valve 160 are closed to isolate the furnace tube 110 from the external environment and prevent external air from entering the furnace tube 110 during the material heating process.

[0041] Optionally, referring to Figure 2, a first pressure gauge 170 is installed on the inlet pipe 130, and a second pressure gauge 180 is installed on the outlet pipe 140. The first and second pressure gauges 170 and 180 can detect the pressure inside the furnace tube 110, preventing excessive pressure from causing the furnace tube 110 to crack. Furthermore, before releasing the material box 10, the pressure inside the furnace tube 110 must be at atmospheric pressure or slightly positive pressure before opening the sealing structure 300, thus preventing a large amount of other gases from the quenching container 200 from entering the furnace tube 110 after the sealing structure 300 is opened. Additionally, if rapid cooling of the material is required, some of the inert gas in the furnace tube 110 must be discharged so that its pressure is essentially the same as the pressure in the quenching container 200.

[0042] Referring to Figure 4, the inlet pipe 130 is positioned near the first end 111, and the outlet pipe 140 is positioned near the second end 112. It can be understood that by positioning the inlet pipe 130 near the first end 111 and the outlet pipe 140 near the second end 112, it ensures that there is virtually no air near the second end 112 of the furnace tube 110, which is close to the quenching container 200. Thus, when the sealing structure 300 is opened, almost no trace amount of air remaining in the furnace tube 110 will enter the quenching container 200, further reducing the probability of the material coming into contact with air during quenching, thereby improving the material's performance. Furthermore, because air has a higher density than nitrogen, helium, etc., positioning the inlet pipe 130 near the first end 111 and the outlet pipe 140 near the second end 112 allows for faster air removal.

[0043] Referring to Figure 2, the quenching container 200 has an exhaust port, and an exhaust pipe 240 connected to the exhaust port is provided on the quenching container 200. A one-way exhaust valve 250 is provided on the exhaust pipe 240. It can be understood that during actual operation, when quenching is required, easily vaporizable liquids such as liquid nitrogen (liquid argon, dry ice) are added from the quenching agent injection port. At least part of the quenching agent vaporizes and fills the quenching container 200. Under pressure, the original air inside the quenching container 200 is discharged through the one-way exhaust valve 250, making the entire quenching container 200 air-free. Thus, when the sealing structure 300 is opened, and the material box 10 falls into the quenching chamber 210 under its own gravity for quenching, the material box 10 is prevented from contacting air, further improving the quenching effect. Of course, in other embodiments of this utility model, the one-way exhaust valve 250 can be directly installed at the exhaust port, and the exhaust pipe 240 is connected to the outlet of the one-way exhaust valve 250.

[0044] In addition, it should be noted that the gas-quenching quenching agent is injected before the sealing structure 300 is opened, and the air in the quenching container 200 is discharged, so that when the material box 10 falls, it avoids contact with the air in the quenching container 200, thereby further improving the air isolation effect during the quenching process.

[0045] Referring to Figure 3, the second end 112 of the furnace tube 110 is provided with a first flange 400, and the quenching container 200 is provided with a second flange 500 around the opening 211. The first flange 400 and the second flange 500 are detachably connected, and the sealing structure 300 is installed below the second flange 500. It can be understood that in actual operation, the detachable connection between the furnace tube 110 and the quenching container 200 is achieved by connecting the first flange 400 and the second flange 500, which facilitates the installation and removal of the quenching container 200 by operators while improving the sealing performance of the connection between the furnace tube 110 and the quenching container 200.

[0046] Optionally, the first flange 400 and the second flange 500 are detachably connected via connectors (screws, pins). This facilitates the operator in installing the quenching container 200 onto or removing it from the furnace tube 110. Of course, in other embodiments of this invention, the first flange 400 and the second flange 500 can be detachably connected via clips or clamps.

[0047] Referring to Figures 1 and 4, the first end 111 of the furnace tube 110 is equipped with a sealing furnace cover 600, and the lifting device 800 is sealed and connected to the sealing furnace cover 600. It can be understood that the installation of the lifting device 800 on the sealing furnace cover 600 ensures good sealing of the first end 111 of the furnace tube 110, preventing external air from entering the interior of the furnace tube 110 during heating, thereby improving the performance of the material. It should be noted that a sealing element can be added between the first end 111 of the furnace tube 110 and the sealing furnace tube 110 to improve the connection sealing.

[0048] Referring to Figures 1 and 3, the quenching equipment for solid electrolytes also includes a housing 700. The housing 700 includes a support base 710 and an insulation shell 720. The insulation shell 720 is connected to the support base 710 and defines an installation cavity. A furnace tube 110 passes through the installation cavity, and a furnace chamber 120 is located within the installation cavity. The first end 111 and the second end 112 of the furnace tube 110 extend out of the installation cavity. A quenching container 200 is installed on the support base 710, wherein the installation cavity is filled with an insulation material layer 721. It is understood that filling the installation cavity with an insulation material layer 721 can reduce the heat diffusion from the furnace chamber 120 to the outside, improve the heating efficiency of the material box 10, and reduce energy consumption. The insulation material layer 721 can be selected according to actual needs, and the specific material of the insulation material is not limited here.

[0049] Optionally, the support base 710 has an L-shaped structure, the quenching container 200 is installed on the horizontal section of the L-shaped structure, the insulation shell 720 is installed on the vertical section of the support base 710, and the vertical section is also provided with a bracket 900 for supporting the furnace tube 110. This can improve the installation stability of the furnace body 100.

[0050] Optionally, referring to Figures 2-3, the quenching container 200 is provided with a quenching agent injection pipe 220 communicating with the quenching agent injection port, and a quenching agent injection control valve 230 is provided on the quenching agent injection pipe 220. It is understood that in actual operation, the quenching agent injection pipe 220 is connected to an external liquid source via a connecting pipe. Opening the quenching agent injection control valve 230 allows the quenching agent to enter the quenching container 200 from the quenching agent injection pipe 220, facilitating the operator to inject the quenching agent into the quenching container 200. Preferably, the quenching agent injection control valve 230 remains open. During the quenching process, an excess of a quenching agent capable of gas quenching, such as liquid nitrogen, is injected, while the excess gas generated by the excessive injection is discharged through the one-way exhaust valve 250. The discharged gas rapidly carries away heat from the quenching container 200, ensuring that the quenching agent in the quenching container 200 maintains a consistently low temperature during the quenching process, resulting in a good quenching effect. Of course, in other embodiments of this utility model, the quenching agent injection control valve 230 can be directly set at the quenching agent injection port, and the quenching agent injection pipe 220 is connected to the outlet of the quenching agent injection control valve 230.

[0051] Optionally, a third pressure gauge 290 is also provided on the quenching agent injection pipe 220, which can detect the air pressure inside the quenching chamber 210. After the quenching agent is injected into the quenching container 200, the quenching agent gradually vaporizes into gas, and the quenching container 200 is filled with a protective atmosphere. The third pressure gauge 290 can monitor that the quenching container 200 is always under positive pressure, so that the material box 10 does not come into contact with air. When the pressure inside the quenching container 200 gradually decreases, it indicates that the quenching agent in the quenching container 200 is basically used up. Before this, the material box 10 in the quenching container 200 is transferred to an inert environment such as a protective atmosphere to further improve the quenching effect.

[0052] Optionally, referring to Figure 3, the quenching container 200 is also provided with an observation port 260 and an illumination element 270 located adjacent to the observation port 260. It is understood that through the observation port 260, users can observe the material state inside the quenching container 200 in real time, facilitating the observation of the quenching effect.

[0053] Optionally, as shown in Figure 3, the quenching container 200 is also provided with a handle 280, which allows the operator to easily move the quenching container 200.

[0054] Referring to Figures 5 and 6, the hoisting device 800 includes a base 810, a drive component 820, and a hook mechanism 830. The base 810 is sealed to the furnace cover 600. The drive component 820 is mounted on the base 810. The hook mechanism 830 is rotatably connected to the base 810 and is also connected to the drive component 820. The drive component 820 can drive the hook mechanism 830 to rotate relative to the base 810, thereby disengaging the lifting cable 20 of the material box 10 from the hook mechanism 830. It can be understood that after the material is heated, the drive component 820 drives the hook mechanism 830 to rotate, which disengages the lifting cable 20 from the hook mechanism 830, thus easily detaching the material box 10 from the hook mechanism 830. It should be noted that the output shaft of the drive component 820 can be directly connected to the hook mechanism 830, or it can be connected to the hook mechanism 830 through a gear transmission assembly or other structure, depending on actual needs.

[0055] Preferably, the hook mechanism 830 is fixedly connected to the base 810, and the unfixed part can rotate around the fixed part in a direction away from the base 810 (under the action of gravity). The driving member 820 includes an electromagnet set on the base 810, and the hook mechanism 830 is made of magnetic material. When the driving member 820 is energized, the hook mechanism 830 is attracted to the base 810 under the action of magnetic force. When the driving member 820 is de-energized, the attraction of the driving member 820 to the hook mechanism 830 disappears, and the part of the hook mechanism 830 that is not fixedly connected to the base 810 is detached from the base 810, thereby causing the hook mechanism 830 to rotate. During the rotation of the hook mechanism 830 relative to the base 810, the suspension wire 20 can be detached from the hook mechanism 830.

[0056] The advantages of the quenching equipment for solid electrolytes in this embodiment are as follows:

[0057] First, the quenching container 200 can use gas quenching agent, which results in a lower quenching temperature and ensures the quenching effect.

[0058] Secondly, the detachable design of the quenching container 200 and the furnace tube 110 enables oxygen-free transfer to an inert atmosphere glove box, avoiding contact between the material and air during conventional quenching and transfer processes, and preventing the material from reacting with oxygen and moisture in the air.
