Description

Technical Field

[0001] The present invention relates to the technical field of solid-state batteries, and in particular to a high-safety solid-state lithium-ion battery with stable electrolyte. Background Art

[0002] Solid-state batteries are a type of battery technology. Unlike the lithium-ion and lithium-ion polymer batteries commonly used today, solid-state batteries use solid electrodes and solid electrolytes. The solid electrolyte is key to achieving high safety, energy density, and cycle life. Polymers, oxides, and sulfides are the three main types of solid-state electrolytes currently used in solid-state batteries.

[0003] Traditional solid-state lithium-ion battery cells are wrapped in a protective shell on the outside of the battery core. The protective shell has a certain impact on the heat dissipation of the battery. The solid electrolyte ion conductivity of the solid-state battery is lower than that of the liquid electrolyte, especially in low-temperature environments, the conductivity performance decays significantly. Therefore, in low-temperature cold areas, it is necessary to reduce the heat dissipation of the battery, that is, to use accumulated heat to keep the battery warm. From the perspective of biomimetics, birds dissipate heat by lifting or removing their feathers, that is, using air convection in exposed areas of the skin to dissipate heat. The hollow structure inside the feathers can effectively seal the air, forming an insulating layer to prevent heat loss and have good thermal insulation performance. If the heat dissipation shell of the solid-state lithium-ion battery is improved to an arrangement structure that mimics bird feathers, the heat dissipation and heat preservation of the solid-state battery can be flexibly adjusted. For this purpose, the present invention provides a high-safety solid-state lithium-ion battery with stable electrolyte. Summary of the Invention

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the technical solutions in the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] See also Figures 1 to 14 The present invention provides a technical solution: a high-safety solid-state lithium-ion battery with a stable electrolyte, comprising:

[0044] Battery box shell 1, both sides of the battery box shell 1 are provided with ventilation plate holes for air circulation;

[0045] A battery core 2 fixed inside the battery case 1, and two scale feather layers 3 arranged inside the battery case 1, the two scale feather layers 3 are distributed on both sides of the heat dissipation surface of the battery core 2, and the scale feather layers 3 cover the ventilation plate holes on the battery case 1;

[0046] An integrated worm 4 is positioned and installed in the battery housing 1. The integrated worm 4 changes the heat dissipation strength by driving the feather layer 3.

[0047] A temperature control layer 5 is provided between the scale-feather layer 3 and the battery core 2 . The temperature control layer 5 controls the nearby scale-feather layer 3 to locally enhance heat dissipation by detecting the local overheating temperature of the battery core 2 .

[0048] refer to Figure 4 It is understood that the scale feather layer 3 includes:

[0049] A row of parallel adjustment shafts 6, one end of which is engaged with the integrated worm 4 through a fixed gear:

[0050] A row of heat insulation panels 7 are installed on the adjustment shaft 6, and one end of each heat insulation panel 7 corresponds to a pressure control unit 8 for contact transmission. The two rows of heat insulation panels 7 on adjacent adjustment shafts 6 are distributed in a fish-scale pattern.

[0051] The integrated worm 4 and the adjusting shaft 6 are in the same spatial position in the battery box shell 1. The partial sections of the integrated worm 4 and the adjusting shaft 6 are movably sleeved in different through holes opened on the shell of the battery box shell 1. One end of the integrated worm 4 extends to the outside of the battery box shell 1. The rotation of the outer end of the integrated worm 4 is controlled by the driving mechanism in the prior art, and then the rotation of the adjusting shaft 6 drives all the heat insulation panels 7 to swing, so that the size of the air circulation channel between the two adjacent heat insulation panels 7 changes. When the heat insulation panels 7 gradually swing toward the heat dissipation surface of the battery core 2, one heat insulation panel 7 will gradually fit with the surrounding heat insulation panels 7, reducing the heat leakage from the heat dissipation surface of the battery core 2. This simulates the heat insulation and heat preservation function of the bionic bird feathers, so that the solid-state lithium battery can be used in cold areas. Conversely, the heat insulation panel 7 gradually swings away from the heat dissipation surface of the battery core 2, and the heat dissipation space between adjacent heat insulation panels 7 is increased, and the heat on the heat dissipation surface of the battery core 2 can be more easily discharged through the heat dissipation space around the heat insulation panel 7.

[0052] refer to Figure 5 It is understood that the temperature control layer 5 includes:

[0053] A row of concave long frames 9 whose ends are fixed to the battery box shell 1, and a row of heat-conducting frames 10 fixed to each concave long frame 9. The heat-conducting frames 10 have channels for storing thermal expansion and contraction gases. Each heat-conducting frame 10 is connected to a corresponding voltage control unit 8, and each heat-conducting frame 10 corresponds to a heat insulation plate 7;

[0054] A closed-loop belt 11 for reciprocating conveying, and a plurality of shift blocks 12 fixed on the closed-loop belt 11, each shift block 12 is distributed at one end of a pressure control unit 8, a wave surface is provided on the shift block 12, and a supporting roller 13 is provided at the turning bend on the closed-loop belt 11, and one end of the rotating shaft on the roller 13 extends to the outside of the battery box shell 1, and the rotation of the rotating shaft of part of the roller 13 is controlled by the rotating mechanism in the prior art, and then the rotation of the roller 13 drives the closed-loop belt 11 for reciprocating conveying.

[0055] refer to Figure 8 It is understood that the insulation board 7 includes an insulation board 16, a return spring 15 in contact with one side of the insulation board 16, a row of elastic strips 14 connected to the insulation board 16, a rotating cylinder 17 fixedly connected to the insulation board 16, and a push cylinder 18 in contact with one end of the rotating cylinder 17. One end of the insulation board 16 is movably sleeved on the adjustment shaft 6 by setting a cylinder body, one end of the return spring 15 is fixed on the adjustment shaft 6, one end of the elastic strip 14 is fixed on the insulation board 16, and the other end of the elastic strip 14 covers the ventilation strip hole opened on the insulation board 16.

[0056] The rotary cylinder 17 and the push cylinder 18 are both sleeved on the adjusting shaft 6. The push cylinder 18 is provided with a slider inside to be stuck into the slide groove opened on the outer wall of the adjusting shaft 6. A protrusion is provided on the bottom surface of the push cylinder 18, and the push cylinder 18 is pushed axially to make the protrusion push the inclined surface set on the edge of the rotary cylinder 17.

[0057] The present invention cushions external accidental impacts by arranging multiple heat insulation plates 16 in a fish-scale pattern. When a foreign object hits the scale layer 3, the heat insulation plate 16 at the impact point is compressed by the foreign object, and the heat insulation plate 16 swings. The return spring piece 15 rebounds to hinder the swing of the heat insulation plate 16. During the swinging process of the heat insulation plate 16, the heat insulation plate 16 will compress some of the surrounding heat insulation plates 16. After the surrounding heat insulation plates 16 swing, they will continue to transmit and compress more heat insulation plates 16. That is, when a foreign object hits a small number of heat insulation plates 16, more heat insulation plates 16 will be caused to cushion the impact force. Each heat insulation plate 16 is supported by a corresponding return spring piece 15. Therefore, the fish-scale arrangement of many heat insulation plates 16 can intercept strong impacts and protect the internal battery core 2. The fish-scale protection has another advantage. If more heat insulation plates 16 are densely arranged, after a single heat insulation plate 16 is damaged, the damaged position is still covered and protected by other intact heat insulation plates 16. This is similar to the function of fish-scale armor worn by ancient soldiers.

[0058] The fish scale arrangement of the heat insulation board 16 of the present invention is also similar to the arrangement of bird feathers, which can achieve heat dissipation and heat preservation by imitating bird feathers. Figure 8 One side of the heat insulation plate 16 is pushed by the return spring 15. Although the heat insulation plate 16 has a tendency to swing upward, the heat insulation plate 16 drives the rotating cylinder 17, and the rotating cylinder 17 is pushed by the stationary push cylinder 18 on the right side. In this way, the heat insulation plate 16 and the adjustment shaft 6 remain in a relatively static state. All the adjustment shafts 6 rotate synchronously, which will cause all the heat insulation plates 16 to swing synchronously. When all the heat insulation plates 16 swing synchronously and stick to the battery core 2, multiple heat insulation plates 16 gradually play a covering and heat preservation effect. Conversely, when all the heat insulation plates 16 swing away from the battery core 2, more heat dissipation space will be left between the two adjacent covering heat insulation plates 16. In this way, the heat generated by the battery core 2 during operation will be more easily transmitted through the scale feather layer 3, achieving a better heat dissipation effect.

[0059] refer to Figure 8, the cylinder at the end of the heat insulation plate 16 is stuck in the annular groove provided on the adjusting shaft 6, so that the heat insulation plate 16 can rotate relative to the adjusting shaft 6, but cannot move axially along the adjusting shaft 6, the push cylinder 18 slides to the left, and the convex block of the push cylinder 18 pushes the rotary cylinder 17, which causes the rotary cylinder 17 to rotate, and the rotary cylinder 17 drives the heat insulation plate 16, and the heat insulation plate 16 swings downward, and no force is applied to the push cylinder 18. The return spring piece 15 pushes the heat insulation plate 16, and the heat insulation plate 16 rises and swings back to its original position. Therefore, by continuously and intermittently pressing the push cylinder 18 to the left, the heat insulation plate 16 can be controlled to swing continuously, and the heat insulation plate 16 supplies air to the heat dissipation surface of the battery core 2 by continuous swinging. Figure 8 , the area below the heat insulation plate 16 is the heat dissipation surface of the battery core 2. When the heat insulation plate 16 swings downward, the air below the heat insulation plate 16 is directly pushed toward the battery core 2. The injected air dissipates the local heat accumulation on the battery core 2. During the upward swinging process of the heat insulation plate 16, the air above the heat insulation plate 16 passes through the ventilation holes on the heat insulation plate 16 by lifting the elastic strip plate 14, that is, the new air from the outside will flow under the heat insulation plate 16. Next, the heat insulation plate 16 swings downward again, and the new air under the heat insulation plate 16 is pushed toward the heat accumulation area on the battery core 2 again. In this way, the heat insulation plate 16 swings continuously, and the new air from the outside is continuously transported to the heat accumulation area on the battery core 2, achieving the effect of local cooling.

[0060] refer to Figure 10 It is understood that the pressure control unit 8 includes a unit pile block 24 fixed on the concave long frame 9, an L-shaped pressure plate 25 sliding through the plate hole opened on the unit pile block 24, a deformation part 21 set at one end of the L-shaped pressure plate 25, a first wheel head 20 for transmission between the L-shaped pressure plate 25 and the deformation part 21, a hard pipe 19 fixedly connected to the heat conduction frame 10 at one end, a rod 23 connected to the other end of the hard pipe 19, and a second wheel head 22 for establishing transmission between the rod 23 and the deformation part 21. The other end of the L-shaped pressure plate 25 is placed on the push cylinder 18. The L-shaped pressure plate 25 is provided with a plate that limits its own movement range. The deformation part 21 contacts the shift block 12 by extending, and the shift block 12 continuously shifts the contacted deformation part 21 by moving back and forth.

[0061] The deformation portion 21 includes a head plate 28, a J-shaped tail plate 29 supported at one end of the head plate 28, a branch worm 27 with a row of teeth meshing and transmission provided on the J-shaped tail plate 29, and a long shaft gear 26 fixed coaxially with the branch worm 27. The branch worm 27 is movably sleeved in a through hole opened on a protrusion provided on the head plate 28.

[0062] The unit pile block 24 is provided with a T-shaped block to be inserted into the T-shaped slot provided on the head plate 28 . Cross prisms are fixed on both sides of the J-shaped tail plate 29 , and the cross prisms are slidably inserted into the cross slot provided on the head plate 28 .

[0063] The rod 23 includes a temperature control rod 30 with one end slidingly inserted into the end of the hard tube 19, a guide rod 32 fixed at the other end of the temperature control rod 30, and a spring 31 sleeved on the guide rod 32. The guide rod 32 slides through the column hole opened on the unit pile block 24, and the spring 31 is supported between the temperature control rod 30 and the unit pile block 24.

[0064] The second wheel head 22 includes a first shaft 34 movably sleeved in a through hole opened on the unit pile block 24, a first shaft gear 33 fixed at one end of the first shaft 34, and a first stroke gear 35 fixed at the other end of the first shaft 34. The first stroke gear 35 and the long shaft gear 26 are engaged for transmission, and the first shaft gear 33 and the rack provided on the temperature control rod 30 are engaged for transmission.

[0065] The first wheel head 20 includes a second shaft 37 movably sleeved in a rough hole provided on the unit pile block 24, a second stroke gear 36 fixed at one end of the second shaft 37, and a second shaft gear 38 fixed at the other end of the second shaft 37. The second stroke gear 36 is engaged with a row of teeth provided on the L-shaped pressure plate 25 for transmission, and the second shaft gear 38 is engaged with a row of teeth provided on the head plate 28 for transmission.

[0066] Under normal circumstances, the heat is dissipated from the side of the battery core 2, and the heat will pass through the scale feather layer 3, so that the battery core 2 is effectively cooled. However, the battery core 2 itself may have uneven heat dissipation, that is, the heat dissipation plate surface on the battery core 2 has a problem of high temperature. Other areas dissipate heat normally, while the high temperature area needs to enhance heat dissipation. The heat insulation plate 16 near the normal heat dissipation area remains stationary, while the heat insulation plate 16 near the high temperature area can be enhanced by continuously swinging. Figure 2 It can be further understood that at this time all the insulation plates 16 are stationary, and the heat dissipation levels at various locations on the internal battery cells 2 are similar. However, if some of the insulation plates 16 swing automatically, it means that there is heat accumulation inside the areas covered by these insulation plates 16, which may be a problem caused by local overheating of the battery cells 2. The insulation plates 16 swing continuously to control the external air supply to impact the overheated areas of the battery cells 2, thereby avoiding continued temperature rise affecting the battery cells 2.

[0067] The principle of the swinging process of the heat shield 16 is as follows: if the battery cell 2 is locally overheated, the heat at the corresponding position is transferred to the nearby heat-conducting frame 10. Each heat-conducting frame 10 corresponds to the swinging of one heat shield 16. Specifically, the gas in the heat-conducting frame 10 expands due to heat, and the internal air pressure acts on the temperature control rod 30 through the hard tube 19. Figure 13The temperature control rod 30 gradually extends from the hard tube 19, and the temperature control rod 30 moves to the right to drive the second wheel head 22, and then the long shaft gear 26 drives the branch worm 27 to rotate. The rotation of the branch worm 27 causes the J-shaped tail plate 29 to move. At this time, the position of the head plate 28 remains unchanged, the overall length of the deformation portion 21 increases, and the J-shaped tail plate 29 contacts the shift block 12. It should be added here that when the battery cell 2 is working normally, there is no problem of local excessive heating on the battery cell 2, and the final contact between the J-shaped tail plate 29 and the shift block 12 will not occur.

[0068] After the battery cell 2 is put into operation, the closed-loop belt 11 continuously reciprocates to transport it, controlling all the shifting blocks 12 to continuously move back and forth. The temperature of the battery cell 2 is locally high, and the J-shaped tail plate 29 in this area contacts the shifting blocks 12. In this way, the shifting blocks 12 continuously shift the J-shaped tail plate 29. Figure 13 The deformation part 21 in the middle is continuously raised and lowered synchronously as a whole. When the deformation part 21 rises once, the rising head plate 28 drives the first wheel head 20 to rotate, causing the L-shaped pressure plate 25 to translate. The translated L-shaped pressure plate 25 presses the push cylinder 18. As mentioned before, the push cylinder 18 moves axially on the adjusting shaft 6. The push cylinder 18 presses the rotating cylinder 17, which will eventually cause the heat insulation plate 16 to swing. Therefore, the shifting block 12 at the source continuously shifts the J-shaped tail plate 29, which will eventually cause the corresponding heat insulation plate 16 to swing continuously.

[0069] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
