Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and particularly to a solid-state battery with a heat-dissipating and explosion-proof protective housing. Background Art

[0002] With the rapid development of electric vehicles and portable electronic devices, the demand for batteries with high energy density and high safety is becoming increasingly urgent. Solid-state batteries, due to their use of solid electrolytes, have higher safety and energy density compared to traditional liquid lithium batteries and are considered strong competitors for next-generation battery technologies. However, solid-state batteries still face safety hazards caused by thermal runaway in practical applications.

[0003] During the operation of solid-state batteries, heat is generated due to internal electrochemical reactions, interfacial impedance, and other factors. Under normal operating conditions, this heat can be effectively dissipated through the battery's own thermal management system. However, when the battery encounters abnormal conditions such as overcharging, over-discharging, and short-circuiting, the internal heat will increase sharply, causing the battery temperature to rise rapidly. If the heat cannot be dissipated in time, a series of chain reactions will occur, such as the failure of the solid electrolyte interface, the decomposition of electrode materials, and thermal runaway. When the internal temperature of the battery reaches the critical point, it may lead to serious safety accidents such as battery fire and explosion. Currently, the overall battery thermal management system is relatively complex, requiring additional space and energy consumption, and it is difficult to handle emergency situations of local overheating inside the battery. Summary of the Invention

[0016] Preferably, the inward-opening conical plug structure includes a lower retaining ring and a first conical plug arranged in the liquid feeding pipe and the recovery pipe.

When the recovery pipe is docked with the liquid outlet pipe, the pressure rod on the pointed end can squeeze the sloped seat from the side, so that the second conical plug moves down and opens. A heat dissipation structure is provided on the liquid storage box.

[0018] Preferably, shaft seats are provided on both sides of the protective housing. A rotating shaft passing through both ends of the protective housing is installed on the shaft seats.

A push rod is linearly driven and installed on the driving structure. When the push rod moves, it can press the translation seat inward through the convex block.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. The solid-state battery of the present invention can perform efficient emergency heat dissipation. The heat absorption elbow is embedded in the battery cell assembly structure of the encapsulation inner shell, and cooperates with the liquid storage box to form an efficient coolant circulation heat dissipation path. When the battery temperature is too high, the liquid storage box can quickly input the coolant into the heat absorption elbow through the liquid supply pipe and the inlet pipe. The coolant flows in the heat absorption elbow and efficiently absorbs the heat generated by the battery cell module. Then, it returns to the liquid storage box through the outlet pipe and the recovery pipe. This process directly dissipates heat from the internal heat source of the battery, effectively avoiding the occurrence of thermal runaway, and can avoid additional energy loss, and is driven by heat. At the same time, the battery cell module is installed in a movable manner. During emergency heat dissipation, the pushing structure can move the assembly seat, making the battery cell module closely fit with the partition plate equipped with the heat absorption elbow, greatly increasing the heat transfer area, improving the heat absorption efficiency of the heat absorption elbow, and ensuring that a large amount of heat can be quickly taken away in an emergency to ensure the safety of the battery.

[0026] 2. The drive structure of the present invention operates automatically based on the battery temperature monitored in real time by the temperature-measuring push rod. The temperature-measuring push rod can adopt a cylinder structure with a temperature sensor or a piston rod structure filled with thermally expandable gas. When the temperature of the encapsulation inner shell is detected to be too high, the temperature-measuring push rod drives the rack on the sliding seat to move, driving the gear to rotate, and then causing the rotating shaft to rotate, driving the liquid storage box to rotate from the bottom of the protective outer shell to the top, automatically opening the coolant input for emergency heat dissipation. After the temperature drops, it can automatically control the liquid storage box to rotate back to recover the coolant. The whole process does not require manual intervention, and when using the piston rod structure, it does not consume the energy of the battery, providing longer battery life compared to traditional heat dissipation systems.

[0027] 3. The present invention ingeniously integrates heat dissipation and protection components such as the heat-absorbing elbow pipe, liquid storage box, and drive structure between the encapsulation inner shell and the protective outer shell. Compared with traditional complex battery thermal management systems, it does not require additional large amounts of space, making the overall structure of the battery more compact and more suitable for applications in fields with strict space requirements such as electric vehicles and portable electronic devices.

[0042] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] See also Figures 1 to 13 The present invention provides a technical solution: a solid-state battery with a heat-dissipating explosion-proof protective shell 4.

[0044] like Figures 1 - 5 As shown, the solid-state battery adopts a double-layer shell structure, including an inner shell 1 and a protective outer shell 4. The inner shell 1 is provided with partitions 2 arranged at equal intervals, and the battery cell module 3 is installed in the installation space formed by the partitions 2. The inner shell 1 is a layer of highly thermally conductive material, such as graphene composite material or high-purity copper, which can quickly conduct away the heat generated by the battery. The protective outer shell 4 is provided with heat dissipation grooves 5, which mainly provide protection. An air cooling device is installed between the inner shell 1 and the protective outer shell 4 to dissipate heat through the heat dissipation grooves 5.

[0045] like Figure 5 , Figure 6As shown, a heat-absorbing bent pipe 6 is also preset in the partition plate 2 of the present invention for emergency heat dissipation inside the battery. The top end of the heat-absorbing bent pipe 6 is connected to a liquid inlet pipe 7, and the bottom end is connected to a temporary storage box 8. Moreover, a liquid outlet pipe 9 is provided at the bottom of the temporary storage box 8, thus forming a complete passage. When the temperature inside the battery is too high, the coolant can be input into the heat-absorbing bent pipe 6 from the liquid inlet pipe 7, flow through the partition plate 2, quickly absorb heat, then flow into the temporary storage box 8, and finally flow out from the liquid outlet pipe 9.

[0046] As Figures 7 - 11 shown, at the same time, shaft seats 10 are provided on both sides of the protective housing 4. A rotating shaft 11 passing through both ends of the protective housing 4 is installed on the shaft seats 10. The rotating frame 12 is installed through the rotating shaft 11, and a liquid storage box 13 is fixedly installed on the rotating frame 12. Therefore, the position of the liquid storage box 13 can be changed by the rotation of the rotating shaft 11. The liquid storage box 13 can rotate up and down on the side of the protective housing 4. The liquid storage box 13 is pre-filled with coolant. Through the up and down rotation of the liquid storage box 13, the feeding and recycling of the coolant are carried out, and it cooperates with the heat-absorbing bent pipe 6 to play a role in emergency heat dissipation. A liquid supply pipe 14 and a recovery pipe 15 are arranged side by side on the liquid storage box 13. Under normal circumstances, the liquid storage box 13 is stored at the bottom of the protective housing 4 to dissipate heat from the coolant therein and keep it in a low-temperature state. When the temperature inside the battery is too high, the liquid storage box 13 rotates to the top of the protective housing 4 along with the rotating frame 12, and the coolant is input into the liquid inlet pipe 7 through the liquid supply pipe 14, and the emergency heat dissipation inside the battery is carried out through the flowing coolant. After the temperature inside the battery returns to normal, the liquid storage box 13 can rotate back to the bottom, and the coolant is recovered into the liquid storage box 13 through the docking of the liquid outlet pipe 9 and the recovery pipe 15.

[0047] As Figures 7 - 11As shown, the liquid supply pipe 14 of the present invention can cooperate with the liquid inlet pipe 7, and the liquid outlet pipe 9 and the recovery pipe 15 can cooperate with each other, thereby completing the recycling work of the coolant. Among them, the liquid supply pipe 14 and the recovery pipe 15 are both provided with a tapered plug structure that opens in a retracted manner. The tapered plug structure includes a lower retaining ring 16 provided in the liquid supply pipe 14 and the recovery pipe 15 and a first tapered plug 17. The lower retaining ring 16 is fixedly installed, while the first tapered plug 17 is movably arranged. A through groove is provided in the lower retaining ring 16, and an elastic member is connected to the first tapered plug 17. Through the elastic force, the inclined surface of the first tapered plug 17 can press on the lower retaining ring 16 to seal the lower retaining ring 16, so that the coolant will not leak under normal circumstances. A pointed head 18 protruding from the liquid supply pipe 14 is connected to the first tapered plug 17 of the liquid supply pipe 14, and a notch 20 is provided at the end of the liquid inlet pipe 7. A stop rod 21 is provided at the notch 20. When the liquid supply pipe 14 moves onto the liquid inlet pipe 7, the pointed head 18 moves into the notch 20 and is pushed by the stop rod 21, so that the first tapered plug 17 moves away from the lower retaining ring 16. The coolant in the liquid storage box 13 can enter the liquid inlet pipe 7 along the pointed head 18 and then enter the heat absorption elbow 6. An extended-opening tapered plug structure is provided in the liquid outlet pipe 9 of the temporary storage box 8, including an upper retaining ring 22 installed in the liquid outlet pipe 9 and a second tapered plug 23. The second tapered plug 23 is movably arranged and connected with an elastic member. The upper retaining ring 22 is provided with a through groove and is installed above the second tapered plug 23. Through the elastic force, the inclined surface of the second tapered plug 23 presses on the upper retaining ring 22 to seal the liquid outlet pipe 9. A bevel seat 24 is connected to the second tapered plug 23, and a pressure rod 19 is connected to the pointed head 18. When the liquid storage box 13 rotates to the lower side, the recovery pipe 15 is at the bottom of the liquid outlet pipe 9, and the pressure rod 19 on the pointed head 18 can squeeze the bevel seat 24 from the side, causing the second tapered plug 23 to move downward to open. The coolant can flow out from the liquid outlet pipe 9. At this time, the second tapered plug 23 can also enter the recovery pipe 15 to squeeze the first tapered plug 17 therein, causing the first tapered plug 17 to open. The coolant enters the liquid storage box 13 from the recovery pipe 15 to complete the recovery work. A heat dissipation structure is usually provided on the liquid storage box 13, which can gradually restore the coolant to a low temperature state for the next use.

[0048] As Figure 7 , Figure 9As shown in the figure, a driving structure for driving the liquid storage box 13 according to temperature is provided inside the protective housing 4. The driving structure includes a first bevel gear 25 mounted on the rotating shaft 11, and also includes a second bevel gear 26 and a driving gear 27 coaxially mounted in the protective housing 4. The first bevel gear 25 meshes with the second bevel gear 26. At the same time, the diameter of the first bevel gear 25 is at least twice that of the second bevel gear 26. A temperature-measuring push rod 28 is also installed in the protective housing 4. It can adopt a cylinder structure with a temperature sensor or a piston rod structure filled with thermally expanded gas. A heat-conducting sheet 29 is provided on the temperature-measuring push rod 28 and is connected to the encapsulation inner shell 1. And a slide seat 30 with a rack 31 is connected to the temperature-measuring push rod 28. When it is detected that the temperature of the encapsulation inner shell 1 is too high, the temperature-measuring push rod 28 can drive the rack 31 to move, drive the driving gear 27, and after transmission, the rotating shaft 11 rotates, so that the liquid storage box 13 rotates from the bottom of the protective housing 4 to the top to input the coolant. Setting the first bevel gear 25 larger than the second bevel gear 26 plays a role similar to a lever to ensure that the thrust of the temperature-measuring push rod 28 can drive the liquid storage box 13 to rotate.

[0049] As Figure 13 shown, limit seats 32 are installed on the upper and lower sides of the protective housing 4. The two limit seats 32 limit the upper and lower positions of the liquid storage box 13. The cross-section of the limit seat 32 is L-shaped. A buffer member 33 is provided on its front surface, and anti-slip layers 34 are provided on both sides. When the liquid storage box 13 rotates into the limit seat 32, the buffer member 33 buffers the liquid storage box 13 to prevent it from being damaged, while the anti-slip layer 34 ensures the stability of the liquid storage box 13 by generating friction to avoid the instability of the liquid storage box 13 and ensure the smooth flow of the coolant. At the same time, the rack 31 of the present invention is an over-movable structure. As Figure 9 shown, after the liquid storage box 13 rotates into the upper limit seat 32 through the action of the rack 31, the rack 31 will disengage from the gear and continue to move forward. At this time, the liquid storage box 13 is positioned by the limit seat 32. When the temperature drops and the rack 31 moves back, there is a non-driving section, so as to give the coolant redundant time to enter the heat absorption elbow 6.

[0050] As Figure 12As shown, the battery cell module 3 of the present invention adopts a movable mounting structure, which is fixed on the mounting seat 35. Usually, two mounting seats 35 are arranged in the gap of the partition plate 2. The two mounting seats 35 are separated by a spring therebetween. At the same time, there is also a certain gap between the battery cell module 3 and the partition plate 2 to ensure that the heat generated by the battery cell module 3 can be dissipated normally. When the coolant enters the heat absorption elbow 6, the mounting seat 35 can be separated to both sides by the pushing structure in the protective housing 4. The mounting seat 35 moves towards the partition plate 2, so that the battery cell module 3 is in contact with the partition plate 2, increasing the heat absorption effect of the heat absorption elbow 6. The pushing structure includes a translation seat 36 slidably mounted in the protective housing 4. A conical head 37 is arranged on the translation seat 36. The conical head 37 is located in the gap between the two mounting seats 35. A convex block 38 is arranged on the side of the translation seat 36. A push rod 39 is connected to the sliding seat 30. When the sliding seat 30 is driven by the rack 31, the push rod 39 can press the translation seat 36 inward through the convex block 38, so that the conical head 37 on the translation seat 36 advances into the gap between the two mounting seats 35, driving the mounting seat 35 to move.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
