Description

Technical Field

[0001] The invention relates to the technical field of batteries, and in particular to a solid-state battery with a heat dissipation and explosion-proof protective shell. Background Art

[0002] With the rapid development of electric vehicles and portable electronic devices, the demand for high energy density and high safety batteries is becoming increasingly urgent. Solid-state batteries are considered to be a strong competitor for the next generation of battery technology because they use solid electrolytes and have higher safety and energy density than traditional liquid lithium batteries. However, solid-state batteries still face safety risks caused by thermal runaway in practical applications.

[0003] During the operation of solid-state batteries, heat will be generated due to internal electrochemical reactions, interface 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 circuit, the internal heat will increase sharply, causing the battery temperature to rise rapidly. If the heat cannot be dissipated in time, it will trigger a series of chain reactions, such as failure of the solid electrolyte interface, decomposition of electrode materials, thermal runaway, etc. When the internal temperature of the battery reaches the critical point, it may cause serious safety accidents such as battery fire and explosion. The current battery thermal management system is relatively complex as a whole, requiring additional space and energy consumption, and it is difficult to cope with emergencies of local overheating inside the battery.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The solid-state battery of the present invention can perform efficient emergency heat dissipation. A heat-absorbing elbow is provided to be embedded in the battery cell assembly structure of the encapsulated 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-absorbing elbow through the liquid supply pipe and the liquid inlet pipe. The coolant flows in the heat-absorbing elbow, efficiently absorbs the heat generated by the battery cell module, and then returns to the liquid storage box through the liquid outlet pipe and the recovery pipe. This process directly dissipates heat for the internal heat source of the battery, effectively avoids the occurrence of thermal runaway, and can be driven by heat without additional energy loss. 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, so that the battery cell module is closely fitted with the partition equipped with the heat-absorbing elbow, which greatly increases the heat transfer area and improves the heat absorption efficiency of the heat-absorbing elbow, ensuring that a large amount of heat can be quickly taken away in an emergency and ensuring battery safety.

[0017] 2. The driving structure of the present invention operates automatically according to 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 equipped with thermal expansion gas. When it is detected that the temperature of the inner shell of the package is too high, the temperature measuring push rod drives the rack on the slide to move, drives the gear transmission, and then rotates the shaft, driving the liquid storage box to rotate from the bottom of the protective shell to the top, automatically opening the coolant input for emergency heat dissipation. After the temperature drops, the liquid storage box can be automatically controlled to rotate and recover the coolant. The whole process does not require human intervention, and when the piston rod structure is adopted, it does not need to consume battery energy. Compared with the traditional heat dissipation system, it can provide battery life.

[0018] 3. The present invention cleverly integrates heat-absorbing elbows, liquid storage boxes, drive structures and other heat dissipation and protection components between the package inner shell and the protective outer shell. Compared with the traditional complex battery thermal management system, it does not need to occupy a large amount of additional space, making the overall battery structure more compact and more suitable for applications in electric vehicles and portable electronic devices with strict space requirements.

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. 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.

[0034] See also Figures 1 to 13 The present invention provides a technical solution: a solid-state battery with a heat dissipation and explosion-proof protective shell 4.

[0035] like Figure 1-Figure 5 As shown, the solid-state battery adopts a double-layer shell structure, including a package inner shell 1 and a protective outer shell 4. The package inner shell 1 is provided with partitions 2 arranged at equal intervals, and the battery module 3 is installed in the installation space formed by the partitions 2. Among them, the package inner shell 1 is a high thermal conductivity material layer, such as a graphene composite material or high-purity copper, which can quickly conduct the heat generated by the battery, and the protective outer shell 4 is provided with a heat dissipation groove 5, which mainly plays a protective role. An air cooling device is provided between the package inner shell 1 and the protective outer shell 4, which can dissipate heat from the heat dissipation groove 5.

[0036] like Figure 5 , Figure 6As shown, a heat absorbing curved pipe 6 is also preset in the partition 2 of the present invention for emergency heat dissipation inside the battery. The top of the heat absorbing curved pipe 6 is connected to a liquid inlet pipe 7, and the bottom is connected to a temporary storage box 8, and a liquid outlet pipe 9 is arranged at the bottom of the temporary storage box 8, thereby forming a complete passage. When the temperature inside the battery is too high, the coolant can be input from the liquid inlet pipe 7 into the heat absorbing curved pipe 6, flow through the partition 2, quickly absorb heat, and then flow into the temporary storage box 8, and finally flow out from the liquid outlet pipe 9.

[0037] like Figure 7-Figure 11 As shown, at the same time, shaft seats 10 are provided on both sides of the protective shell 4, and rotating shafts 11 penetrating through the two ends of the protective shell 4 are installed on the shaft seats 10, and 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, so that the position of the liquid storage box 13 can be changed by rotating the rotating shaft 11, and the liquid storage box 13 can be rotated up and down on the side of the protective shell 4, and the liquid storage box 13 is pre-installed with coolant, and the liquid storage box 13 is rotated up and down to feed and recover the coolant, and cooperate 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 shell 4 to dissipate the coolant therein and keep it at a low temperature. When the temperature inside the battery is too high, the liquid storage box 13 rotates to the top of the protective shell 4 along with the rotating frame 12, and the coolant is input into the liquid inlet pipe 7 through the liquid supply pipe 14. Emergency heat dissipation in the battery is performed by the flowing coolant. After the temperature inside the battery returns to normal, the liquid storage box 13 can be rotated 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.

[0038] like Figure 7-Figure 11As shown, the liquid feed 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 circulation of the coolant, wherein the liquid feed pipe 14 and the recovery pipe 15 are both provided with a retracted open conical plug structure, the conical plug structure includes a lower retaining ring 16 and a first conical plug 17 arranged in the liquid feed pipe 14 and the recovery pipe 15, the lower retaining ring 16 is fixedly installed, and the first conical plug 17 is movably arranged, the lower retaining ring 16 is provided with a through groove, and the first conical plug 17 is connected to an elastic member, and the inclined surface of the first conical plug 17 can be adjusted by elastic force The lower retaining ring 16 is pressed on to seal the lower retaining ring 16 so that the coolant will not leak under normal circumstances. The first conical plug 17 of the liquid supply tube 14 is connected with a pointed head 18 protruding from the liquid supply tube 14. A notch 20 is provided at the end of the liquid inlet tube 7. A baffle 21 is provided at the notch 20. When the liquid supply tube 14 moves onto the liquid inlet tube 7, the pointed head 18 moves into the notch 20 and is pushed by the baffle 21, so that the first conical plug 17 moves and disengages from the lower retaining ring 16. The coolant in the liquid storage box 13 can enter the liquid inlet tube 7 along the pointed head 18 and then enter the heat absorption bent tube 6. The liquid outlet pipe 9 of the temporary storage box 8 is provided with a tapered plug structure that can be extended and opened, including an upper retaining ring 22 and a second tapered plug 23 installed in the liquid outlet pipe 9. 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. The inclined surface of the second tapered plug 23 is pressed on the upper retaining ring 22 by elastic force to close the liquid outlet pipe 9. The second tapered plug 23 is connected to an inclined seat 24, and the pointed head 18 is connected to a pressing rod 19. When the liquid storage box 13 is rotated to the bottom, the recovery pipe 10 is opened. 15 is at the bottom of the liquid outlet pipe 9, and the pressure rod 19 on the pointed head 18 can squeeze the inclined seat 24 from the side, so that the second conical plug 23 moves down and opens, and the coolant can flow out of the liquid outlet pipe 9. At this time, the second conical plug 23 can also enter the recovery pipe 15, squeeze the first conical plug 17 therein, so that the first conical plug 17 opens, and the coolant enters the liquid storage box 13 from the recovery pipe 15 to complete the recovery work. The liquid storage box 13 is usually provided with a heat dissipation structure, which can gradually restore the coolant to a low temperature state for next use.

[0039] like Figure 7 , Fig. 9As shown, a driving structure for driving the liquid storage box 13 according to the temperature is arranged in the protective shell 4, and the driving structure includes a first bevel gear 25 installed on the rotating shaft 11, and also includes a second bevel gear 26 and a driving gear 27 coaxially installed in the protective shell 4. The first bevel gear 25 is meshed with the second bevel gear 26. At the same time, the wheel 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 shell 4, which can adopt a cylinder structure with a temperature sensor or a piston rod structure with a thermal expansion gas. The temperature measuring push rod A heat conducting sheet 29 is provided on 28 and connected to the package 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 package 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, thereby rotating the liquid storage box 13 from the bottom of the protective shell 4 to the top, and inputting the coolant. The first bevel gear 25 is set larger than the second bevel gear 26, which plays a role similar to a lever, ensuring that the thrust of the temperature measuring push rod 28 can drive the liquid storage box 13 to rotate.

[0040] like Fig.13 As shown, limit seats 32 are also installed on the upper and lower sides of the protective shell 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, and a buffer 33 is provided on the front side, and an anti-skid layer 34 is provided on both sides. When the liquid storage box 13 rotates into the limit seat 32, the buffer 33 is used to buffer the liquid storage box 13 to prevent it from being damaged, and the anti-skid layer 34 ensures the stability of the liquid storage box 13 by generating friction, avoids the instability of the liquid storage box 13, and ensures that the coolant can flow smoothly. At the same time, the rack 31 of the present invention is an excessively movable structure, such as Fig. 9 As shown, after the liquid storage box 13 is rotated to the top 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, and when the temperature drops and the rack 31 moves back, there is a non-driven section, thereby giving the coolant redundant time to enter the heat absorption bend 6.

[0041] like Fig.12As shown, the battery cell module 3 of the present invention adopts a movable installation structure, which is fixed on the assembly seat 35. Two assembly seats 35 are usually arranged in the gap of the partition 2. The two assembly seats 35 are blocked by a spring therebetween. At the same time, there is a certain gap between the battery cell module 3 and the partition 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 assembly seat 35 can be separated to both sides by the pushing structure in the protective shell 4, and the assembly seat 35 moves toward the partition 2, so that the battery cell module 3 fits the partition 2, thereby increasing the heat absorption effect of the heat absorption elbow 6. The pushing structure includes a translation seat 36 slidably installed in the protective shell 4, and a cone head 37 is provided on the translation seat 36. The cone head 37 is located in the gap between the two assembly seats 35. A protrusion 38 is provided on the side of the translation seat 36, and a push rod 39 is connected to the slide seat 30. When the slide seat 30 is driven by the rack 31, the push rod 39 can press the translation seat 36 inward through the protrusion 38, so that the cone head 37 on the translation seat 36 is fed into the gap between the two assembly seats 35, driving the assembly seat 35 to move.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
