[0002] With the development of battery technology, the performance of existing liquid lithium batteries has reached its limit. Therefore, the development direction of battery technology is towards solid-state lithium batteries. Solid-state lithium batteries use a glass compound made of lithium and sodium as the conductive material, replacing the electrolyte of previous lithium batteries, which greatly improves the energy density of lithium batteries. After the solid-state battery is manufactured, it needs to be packaged before it can be put into use.

However, most existing encapsulation methods use welding or multiple bolts to fix the caps. This encapsulation method makes the disassembly of the protective shell and caps cumbersome and complicated when the solid-state lithium battery is damaged and needs to be repaired. This wastes the time and energy of repair personnel, slows down the repair efficiency of solid-state lithium batteries, and reduces the performance of solid-state lithium batteries.

[0036] Working principle: When encapsulating a solid-state lithium battery, the lithium battery body 2 is first placed inside the protective shell 1. Then, the sealing sheet 4 is placed on the upper surface of the protective shell 1, and the positioning block 5 is inserted into the positioning hole. Next, the cover 6 is brought close to the protective shell 1, and the two levers 16 are pulled closer to each other. The levers 16 pull the extension block 14 to slide inside the slide groove through the rotating plate 15. At the same time, the driving block 11 slides along the outer surface of the slide rod 10 inside the inner cavity 9. The spring 13 is compressed and deformed. At the same time, the driving block 11 drives the fixing block 12 to move into the inner cavity 9. Then, the cover 6 is placed on the upper surface of the protective shell 1, so that the bottom block... 7. Slide the plate into the inside of the protective shell 1, insert the plate 8 into the inside of the slot, then release the two locking rods 16, the spring 13 returns to its original state, and push the two driving blocks 11 to move along the slide rod 10 to both ends of the cover 6 respectively. At the same time, the fixing block 12 moves into the fixing groove. When the fixing block 12 is inserted into the inside of the fixing groove, the cover 6 is fixed. Then rotate the locking rod 16 towards the locking seat 17. When the locking rod 16 is inserted into the inside of the locking seat 17, the locking rod 16 fixes the driving block 11 through the rotating plate 15 and the extension block 14. The above operations complete the encapsulation of the solid-state lithium battery. Reverse the above operations to unencapsulate the solid-state lithium battery.

[0037] After encapsulation, the rubber ring 19 is fitted onto the outer surface of the protective shell 1, with the bottom end of the rubber ring 19 contacting the bottom plate 18. Then, the pressure ring 20 is fitted onto the outer surface of the protective shell 1, with the lower surface of the pressure ring 20 contacting the rubber ring 19. The positioning plate 21 is inserted into the corresponding positioning groove, and the connecting block 22 slides into the connecting groove 23. Then, the two fixing bolts 24 are tightened. When both fixing bolts 24 are inserted into the fixing holes, the protection of the solid-state lithium battery is completed.
