Abstract
Description
Technical Field
[0001] This application relates to the field of solid-state battery production technology, and more specifically, to a sulfide all-solid-state battery production apparatus and system. Background Technology
[0002] To meet the technical requirements of long range and high safety for new energy vehicles, major automakers are currently developing all-solid-state batteries. At present, there are three main technical routes for all-solid-state batteries: polymer, sulfide, and oxide. Among them, sulfide solid electrolytes have initially met the requirements for ionic conductivity, and further material modification can further improve ionic conductivity and environmental adaptability. The sulfide system has high technological maturity, rapid development progress, and is most likely to be mass-produced in the short term. Overall, it is the best option, and major automakers have chosen sulfide as their preferred technology route for all-solid-state electrolyte materials, making it their main development direction.
[0003] Generally, the sulfide solid electrolyte Li6PS5Cl produces hydrogen sulfide (H2S) in a dry environment with moisture. H2S is a colorless, highly toxic acidic gas. During the development and trial production of sulfide-based all-solid-state battery cells, the release amount and range of hydrogen sulfide need to be carefully controlled for personnel safety reasons. However, existing patents and literature do not provide production methods suitable for the development, trial production, or even small-batch production of sulfide-based all-solid-state batteries. This makes it difficult to effectively guide the development and construction of equipment for sulfide-based all-solid-state battery cell production lines and to effectively achieve hydrogen sulfide concentration control under various operating conditions. Utility Model Content
[0004] The purpose of this application is to provide a sulfide all-solid-state battery production device and system, which can effectively improve the technical effect of controlling hydrogen sulfide concentration under multiple operating conditions.
[0005] In one aspect, this application provides a sulfide all-solid-state battery production apparatus, including a main frame structure, a channel assembly, a fan filter assembly, and a control valve assembly;
[0006] The main frame structure includes a main frame and multiple covers, which are matched and installed with the main frame, and the multiple covers form a sealing cover.
[0007] The channel assembly includes an exhaust channel and a dust removal channel. The exhaust channel is located in the lower layer of the main frame structure, and the dust removal channel is located in the middle layer of the main frame structure.
[0008] The fan filter assembly includes at least one fan filter unit, which is disposed on the upper layer of the main frame structure;
[0009] The control valve assembly includes at least one control valve, which is connected to the interior of the main frame structure via a connecting pipe.
[0010] In the above implementation process, through functional partitioning and modular design, and taking into account the fact that hydrogen sulfide is denser than air, the exhaust duct for hydrogen sulfide ventilation is located in the lower layer of the main frame structure, while the dust removal duct is located in the middle layer of the main frame structure. This effectively utilizes the internal space of the main frame structure and improves the emission efficiency of hydrogen sulfide gas while preventing gas leakage. In addition, by setting up fan filter units and control valves, dual protection is achieved to effectively prevent hydrogen sulfide from flowing back into the interior of the main frame structure. Thus, this sulfide all-solid-state battery production device can achieve the technical effect of effectively improving the control index of hydrogen sulfide concentration under multiple operating conditions.
[0011] Furthermore, the main frame structure also includes multiple sealing gaskets, and two adjacent machine covers are locked and sealed by matching sealing gaskets.
[0012] In the above process, the joint between two adjacent machine covers is sealed by matching and locking gaskets, thereby improving the sealing effect and effectively preventing the leakage of hydrogen sulfide gas.
[0013] Furthermore, the main frame structure also includes multiple connecting support plates, which are installed on the main frame, and the cover is sealed and installed on the main frame through the connecting support plates and sealing gaskets.
[0014] In the above implementation process, by setting up connecting support plates and sealing gaskets, on the one hand, the machine cover is stably installed, and on the other hand, the joint between the machine cover and the main frame is sealed to prevent hydrogen sulfide gas from leaking from the joint between the machine cover and the main frame.
[0015] Furthermore, the main frame structure also includes a movable door, which is rotatably mounted on the machine cover, and the hinges of the movable door are sealed and mounted on the machine cover by a sealing welding process.
[0016] In the above implementation process, a movable door is installed on the machine cover, which allows the main frame structure to be easily opened or closed. The hinges of the movable door are sealed and installed on the machine cover through sealing welding, effectively maintaining the airtightness of the main frame structure when the movable door is closed.
[0017] Furthermore, the main frame structure also includes an equipment observation window, which is located on the movable door or the machine cover.
[0018] In the above implementation process, by equipping the movable door or the machine cover with an observation window, it is convenient to observe the interior of the main frame structure without opening the movable door, monitor the production status of the sulfide all-solid-state battery, and improve production safety.
[0019] Furthermore, the equipment observation window is made of antistatic modified corrosion-resistant polycarbonate, and the equipment observation window is sealed to the sheet metal with a silicone gasket. The equipment observation window is installed on the movable door or the machine cover through the sheet metal.
[0020] In the above process, the equipment observation window is made of antistatic modified corrosion-resistant polycarbonate, which can effectively improve the antistatic and corrosion resistance of the equipment observation window; the equipment observation window is sealed with a silicone gasket to ensure the airtightness of the equipment observation window.
[0021] Furthermore, the fan filter assembly also includes a fan control mechanism, and the fan filter unit is a variable frequency fan filter unit equipped with a communication mechanism, wherein the variable frequency fan filter unit is connected to the fan control mechanism through the communication mechanism.
[0022] In the above implementation process, by using the frequency conversion control of the variable frequency fan filter unit, combined with the exhaust port (channel assembly and control valve assembly) under multiple operating conditions, the thermal temperature field can be effectively controlled, and the dynamic adjustment of the hydrogen sulfide concentration under different operating conditions can be achieved.
[0023] Furthermore, the control valve includes a check valve and a butterfly valve, which are connected in series in the connecting pipeline.
[0024] In the above implementation process, the control valve adopts a combination structure of butterfly valve and check valve to achieve double protection and effectively prevent hydrogen sulfide backflow.
[0025] Furthermore, the ratio of the gap leakage area of the main frame structure to the total surface area of the main frame structure is less than or equal to 0.04%.
[0026] In the above implementation process, the ratio of gap leakage area to total surface area in the main frame structure is less than or equal to 0.04%, which can effectively prevent the leakage of hydrogen sulfide gas and improve the production safety of sulfide all-solid-state batteries.

[0039] Generally, the decomposition formula for the sulfide solid electrolyte Li6PS5Cl is as follows:
[0040] Li6PS5Cl+6H2O→Li3PO4+5H2S+LiCl+2LiOH;
[0041] As shown in the decomposition formula above, the sulfide solid electrolyte Li6PS5Cl will produce hydrogen sulfide (H2S) in a dry environment with moisture. H2S is a colorless, highly toxic acidic gas. According to the "GBZT 259-2014 Guidelines for Occupational Hazard Prevention of Hydrogen Sulfide", the upper limit of occupational exposure to hydrogen sulfide is ≤10 mg / m³. 3 During the development and trial production of sulfide-based all-solid-state battery cells, special control over the release amount and range of hydrogen sulfide is necessary for personnel safety reasons.
[0042] Existing patents and literature do not provide production equipment suitable for the development, trial production, or even small-batch production of sulfide-based all-solid-state batteries, nor do they offer hydrogen sulfide release control logic schemes for such equipment. This makes it impossible to effectively control hydrogen sulfide concentration under multiple operating conditions and to effectively guide the development and construction of sulfide-based all-solid-state battery cell production lines. Existing lithium battery production equipment cannot meet the needs of sulfide-based all-solid-state battery production, and its shortcomings are as follows:
[0043] ① The existing equipment enclosure is only designed to close the door to prevent personnel from being injured by mechanical collisions, and does not take into account the gas sealing at all. Gases generated during the production process will escape outside the equipment enclosure without restriction, and the escape of hydrogen sulfide generated during the production of sulfide solid-state batteries cannot be effectively controlled.
[0044] ② The existing equipment enclosures do not take into account the protection against hydrogen sulfide corrosion in their material selection. The equipment enclosures are in an environment containing hydrogen sulfide for a long time, and cannot effectively maintain the protection requirements of the equipment enclosures against hydrogen sulfide.
[0045] ③ The existing equipment enclosure is normally in a positive pressure environment, which cannot create a negative pressure environment inside the equipment enclosure. In addition to the inability to control the escape of hydrogen sulfide, the stress and deformation of the equipment enclosure under negative pressure conditions have not been considered.
[0046] ④ The existing equipment enclosure ventilation conditions are relatively simple, with only FFU air intake and FFU being a fixed-frequency fan. There is no dedicated exhaust port for multiple operating conditions, which makes it impossible to effectively control the thermal temperature field and even more impossible to achieve dynamic adjustment of hydrogen sulfide concentration under different operating conditions.
[0047] Based on the aforementioned technical problems, this application provides a sulfide all-solid-state battery production apparatus and system. By designing a novel sulfide all-solid-state battery production apparatus and optimizing the equipment's control logic, the dynamic hydrogen sulfide balance requirements under multiple operating conditions can be met, thereby ensuring the safety and reliability of cell development and achieving the technical effect of effectively improving the hydrogen sulfide concentration control index under multiple operating conditions.
[0048] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a sulfide all-solid-state battery production apparatus provided in an embodiment of this application. Figure 2 This is a side view of a sulfide all-solid-state battery production apparatus provided in an embodiment of this application; the sulfide all-solid-state battery production apparatus includes a main frame structure 100, a channel assembly 200, a fan filter assembly 300, and a control valve assembly 400.
[0049] The main frame structure 100 includes a main frame 110 and multiple covers 120, which are matched and installed with the main frame 110, and the multiple covers 120 form a sealing cover.
[0050] The channel assembly 200 includes an exhaust channel 210 and a dust removal channel 220. The exhaust channel 210 is located in the lower layer of the main frame structure 100, and the dust removal channel 220 is located in the middle layer of the main frame structure 100.
[0051] The fan filter assembly 300 includes at least one fan filter unit 310, which is disposed on the upper layer of the main frame structure 100.
[0052] The control valve assembly 400 includes at least one control valve 410, which is connected to the interior of the main frame structure 100 via a connecting pipe.
[0053] In some embodiments, multiple housings 120 are sealed and installed on the main frame 110, thereby forming a sealed production space inside the main frame structure 100 for the production of sulfide all-solid-state batteries; optionally, the materials and structures of the housings 120 meet the performance requirements of the environmental chamber for the production of sulfide all-solid-state batteries, such as structural strength, sealing structure, and corrosion resistance.
[0054] For example, the exhaust duct 210 is set in the lower layer of the main frame structure 100, so that the hydrogen sulfide gas generated during the production process of hydrogen sulfide all-solid-state battery sinks under the action of gravity (the density of hydrogen sulfide gas is greater than the density of air), and is convenient to be discharged through the exhaust duct 210.
[0055] For example, the dust removal channel 220 is set in the middle layer of the main frame structure 100, so that dust (such as aluminum powder) generated during the production process of hydrogen sulfide all-solid-state battery can be directly sucked into the dust removal channel 220 without being dispersed, and then discharged through the dust removal channel 220; optionally, the inlet of the dust removal channel 220 is set in the middle layer of the main frame structure 100, and the outlet of the dust removal channel 220 can be set in the middle layer, lower layer or upper layer of the main frame structure 100, which is only an example and not a limitation.
[0056] For example, by placing the fan filter unit 310 on the upper layer of the main frame structure 100, the exhaust channel of the lower layer is bypassed, and fresh air is sent into the interior of the main frame structure 100 to ensure the normal production of sulfide all-solid-state batteries.
[0057] For example, the control valve 410 and connecting pipe are connected to the interior of the main frame structure 100 to facilitate process exhaust or emergency exhaust; optionally, the control valve assembly includes at least two control valves 410, one control valve 410 for process exhaust and the other control valve 410 for emergency exhaust.
[0058] For example, the connecting pipe at the control valve 410 is provided with an air outlet, which serves as an exhaust outlet for process exhaust or emergency exhaust.
[0059] The sulfide-based all-solid-state battery production apparatus provided in this application, through a modular design with functional partitions, and taking advantage of the fact that hydrogen sulfide is denser than air, places the exhaust duct 210 for hydrogen sulfide exhaust in the lower layer of the main frame structure 100, and the dust removal duct 220 in the middle layer of the main frame structure 100. This effectively utilizes the internal space of the main frame structure 100 and effectively improves the emission efficiency of hydrogen sulfide gas while preventing gas leakage. In addition, by setting up a fan filter unit 310 and a control valve 410, dual protection is achieved, effectively preventing hydrogen sulfide from flowing back into the interior of the main frame structure 100. Thus, this sulfide-based all-solid-state battery production apparatus can achieve the technical effect of effectively improving the control index of hydrogen sulfide concentration under multiple operating conditions.
[0060] In some embodiments, the main frame structure 100 also includes a plurality of gaskets, and two adjacent housings 120 are locked and sealed by matching gaskets.
[0061] For example, the joint of two adjacent machine covers 120 is sealed by matching and locking the sealing gaskets, thereby improving the sealing effect and effectively preventing the leakage of hydrogen sulfide gas;
[0062] Optionally, the joint between two adjacent housings 120 can be sealed using a stainless steel + fluororubber gasket.
[0063] In some embodiments, the main frame structure 100 further includes a plurality of connecting support plates, which are mounted on the main frame 110, and the cover 120 is sealed and mounted on the main frame 110 by the connecting support plates and the sealing gasket.
[0064] For example, by setting a connecting support plate and a sealing gasket, the machine cover 120 is securely installed on the one hand, and the joint between the machine cover 120 and the main frame 110 is sealed on the other hand, so as to prevent hydrogen sulfide gas from leaking from the joint between the machine cover 120 and the main frame 110.
[0065] In some embodiments, the main frame structure 100 also includes a movable door 130, which is rotatably mounted on the machine cover 120, and the hinges of the movable door 130 are sealed to the machine cover 120 by a sealing welding process.
[0066] For example, by installing a movable door 130 on the housing 120, the main frame structure 100 can be easily opened or closed through the movable door 130, and the hinge of the movable door 130 is sealed to the housing 120 by a sealing welding process, so that the airtightness of the main frame structure 100 is effectively maintained when the movable door 130 is closed.
[0067] In some embodiments, the main frame structure 100 also includes an equipment observation window, which is located on the movable door 130 or the machine cover 120.
[0068] For example, by equipping the movable door 130 or the housing 120 with an observation window, it is convenient to observe the interior of the main frame structure 100 without opening the movable door 130, monitor the production status of the sulfide all-solid-state battery, and improve production safety.
[0069] In some implementations, the equipment viewing window is made of antistatic modified corrosion-resistant polycarbonate, and the viewing window is sealed to the sheet metal with a silicone gasket. The viewing window is installed on the movable door or machine cover via the sheet metal.
[0070] For example, the equipment observation window is made of antistatic modified corrosion-resistant polycarbonate, which can effectively improve the antistatic and corrosion resistance of the equipment observation window; the equipment observation window is sealed to the sheet metal with a silicone gasket to ensure the airtightness of the equipment observation window.
[0071] In some embodiments, the fan filter assembly 300 further includes a fan control mechanism, and the fan filter unit 310 is a variable frequency fan filter unit equipped with a communication mechanism, which is connected to the fan control mechanism through the communication mechanism.
[0072] For example, by using the frequency conversion control of the variable frequency fan filter unit, combined with the exhaust port (channel assembly 200 and control valve assembly 400) under multiple operating conditions, the thermal temperature field can be effectively controlled, and dynamic adjustment of the hydrogen sulfide concentration can be achieved under different operating conditions.
[0073] In some embodiments, the control valve 410 includes a check valve 411 and a butterfly valve 412, which are connected in series in the connecting pipe.
[0074] For example, the control valve 410 adopts a combination structure of butterfly valve 412 and check valve 411 to achieve double protection and effectively prevent hydrogen sulfide backflow.
[0075] In some implementations, the ratio of the gap leakage area of the main frame structure 100 to the total surface area of the main frame structure is less than or equal to 0.04%.
[0076] For example, in the surface area of the main frame structure 100, the ratio of the gap leakage area to the total surface area is less than or equal to 0.04%, which can effectively prevent the leakage of hydrogen sulfide gas and improve the production safety of sulfide all-solid-state batteries.
[0077] In some embodiments, this application provides a sulfide all-solid-state battery production system, including sulfide all-solid-state battery production equipment and Figure 1 / Figure 2 The sulfide all-solid-state battery production apparatus shown is installed inside the main frame structure.
[0078] For example, the sulfide all-solid-state battery production equipment is located inside the main frame structure 100, so that when the sulfide all-solid-state battery production equipment is producing solid-state batteries, the dust and hydrogen sulfide gas generated by it will not drift into the production workshop, ensuring the normal operation of the production process.
[0079] For example, the sulfide all-solid-state battery production apparatus and system provided in this application are highly reliable production equipment suitable for the development, trial production, and even small-batch production of sulfide all-solid-state batteries, as well as a hydrogen sulfide release control logic scheme for such equipment, which includes at least the following technical effects:
