Therefore, the development of battery technology now tends to be solid-state batteries, which use glass compounds made of lithium and sodium as conductive materials to replace the electrolyte of previous lithium batteries, greatly improving the energy density of lithium batteries. After the solid-state battery is manufactured, it is packaged and put into use.

[0003] The existing solid-state lithium battery packaging structure uses a plastic or aluminum sealed shell, which prevents the heat and expanded gas inside the lithium battery from dissipating, making it prone to explosion.

[0030] Example:

[0031] See also Figure 1-Figure 9 , the utility model provides a technical solution:

[0032] A solid-state lithium battery packaging structure, comprising an outer shell 1, a packaging shell 2 is installed inside the outer shell 1, the front of the packaging shell 2 is fixedly connected to the outer shell 1 through a mounting plate 3, a packaging groove 4 is opened on the inner side of the packaging shell 2, packaging plates 5 are installed on the left and right sides of the packaging shell 2, and protective plates 6 are installed on the outer sides of the two groups of packaging plates 5. An arc-shaped buffer plate 7 is fixedly connected between the inner side of the protective plate 6 and the packaging plate 5, and multiple groups of buffer springs 8 are fixedly connected to the inner sides of the upper and lower ends of the protective plate 6. The solid-state lithium battery is packaged into the inner side of the packaging groove 4, and then the packaging plate 5 is closed to the left and right sides of the solid-state lithium battery. They are all fixed. When the solid-state lithium battery is in use, the external protection of the packaging shell 2 is improved by the outer protective plate 6, and the arc buffer plate 7 and the buffer spring 8 are used to buffer the collision of the solid-state lithium battery to avoid deformation problems and increase the service life of the solid-state lithium battery. Finally, the solid-state lithium battery is installed into the interior of the outer shell 1 through the mounting plate 3, and the outer shell 1 is used to provide basic external protection. At the same time, when the solid-state lithium battery is in use, its heat can be dissipated from the packaging shell 2 and the packaging plate 5, thereby avoiding the internal heat and collision gas from being unable to dissipate, further improving the heat dissipation effect of the solid-state lithium battery.

[0033] First, the left and right ends of the top of the outer shell 1 are rotatably connected with handles 101, and multiple groups of external heat dissipation grooves 102 are provided on the left and right sides of the outer shell 1. The four corners of the mounting plate 3 are fixedly connected to the outer shell 1 by screws. A pull-out groove 301 is provided on the outside of the mounting plate 3. The handles 101 are used to facilitate the transportation of the outer shell 1. The heat of the solid-state lithium battery inside the outer shell 1 will be applied to the outer shell 1 after dissipation. At this time, the multiple groups of external heat dissipation grooves 102 on the outside of the outer shell 1 are used to improve the external heat dissipation effect of the outer shell 1. The mounting plate 3 is fixedly connected to the outer shell 1 by screws. When the solid-state lithium battery is disassembled, the screws are unscrewed and the packaging shell 2 can be pulled out from the inside of the outer shell 1 through the pull-out groove 301, which is convenient for disassembly of the solid-state lithium battery.

[0034] Furthermore, a plurality of first heat dissipation grooves 201 are provided on the top of the packaging shell 2, a threading groove 202 is provided on the back of the packaging shell 2, and an insulating rubber pad 203 is installed on the inner wall of the packaging shell 2. The heat of the solid-state lithium battery can be dissipated through the plurality of first heat dissipation grooves 201, and the threading groove 202 is used for wiring the solid-state lithium battery. When the solid-state lithium battery is installed into the inner side of the packaging groove 4, the insulating rubber pad 203 can be used to improve the insulation effect of the solid-state lithium battery and can also provide a certain buffering effect against external collisions.

[0036] Furthermore, multiple groups of card blocks 504 are fixedly connected to the inner sides of the two groups of packaging plates 5, and the multiple groups of card blocks 504 are all connected to the packaging shell 2 through the card slots 505. The card blocks 504 are inserted into the card slots 505 on the left and right sides of the packaging shell 2, which facilitates the disassembly of the packaging plates 5, thereby facilitating the disassembly and assembly of the solid-state lithium battery.

[0037] The utility model also provides a lithium battery, further comprising:

[0038] The lithium battery assembly 9 includes a mounting casing 10, a fixed cover plate 11 and a plurality of lithium battery cells 12. The mounting casing 10 is inserted into the inner side of the packaging groove 4. The fixed cover plate 11 is fixed to the bottom of the mounting casing 10 by screws. The plurality of lithium battery cells 12 are all mounted inside the mounting casing 10. The plurality of lithium battery assemblies 9 are mounted on the inner side of the packaging groove 4. The structure is compact while ensuring the protection and heat dissipation effects of the solid-state lithium battery.

[0039] Secondly, multiple groups of second heat dissipation grooves 1001 are provided on the outer sides of the mounting shell 10 and the fixed cover plate 11, and second heat dissipation holes 1002 are provided on the left and right sides of the mounting shell 10 and at the left and right ends of the second heat dissipation grooves 1001. After the multiple groups of lithium battery cells 12 generate heat during operation, the external heat dissipation effect can be improved through the second heat dissipation grooves 1001. At the same time, the heat is introduced into the heat conduction grooves 502 through the second heat dissipation holes 1002, and finally exported to the outside of the packaging plate 5, thereby preventing the heat and expanded gas from being unable to dissipate, and further improving the heat dissipation effect of the solid-state lithium battery.

[0040] Finally, multiple groups of positioning grooves 1003 are opened inside the installation shell 10, and multiple groups of lithium battery cells 12 are installed at equal intervals on the inner side of the positioning grooves 1003. Conductive sheets 1004 are fixedly connected to the inside of the installation shell 10 and on the left and right sides of the lithium battery cells 12. Wiring holes 1005 are opened at the rear ends of the two groups of conductive sheets 1004. Multiple groups of lithium battery cells 12 are installed at equal intervals in the positioning grooves 1003 for easy positioning and assembly, and wiring is performed through the wiring holes 1005 at the rear ends of the conductive sheets 1004, so that the lithium battery cells 12 are used.

[0041] In this embodiment, the implementation scenario is specifically as follows: multiple groups of lithium battery assemblies 9 are installed into the inner side of the packaging slot 4, and then the packaging plate 5 is closed to fix the left and right sides of the lithium battery assembly 9. When the lithium battery assembly 9 is in use, the external protection of the packaging shell 2 is improved by the outer protective plate 6, and the arc buffer plate 7 and the buffer spring 8 are used to buffer the collision of the lithium battery assembly 9 to avoid deformation problems and improve the service life of the lithium battery assembly 9. Finally, the lithium battery assembly 9 is installed into the interior of the outer shell 1 through the mounting plate 3, and the outer shell 1 is used to provide basic external protection. At the same time, when the lithium battery assembly 9 is in use, its heat can be dissipated from the packaging shell 2 and the packaging plate 5, thereby avoiding the internal heat and collision gas from being unable to dissipate, further improving the heat dissipation effect of the lithium battery assembly 9, and the entire operation process is simple and convenient. Compared with the existing solid-state lithium battery packaging structure and lithium battery, the utility model can improve the protection effect and heat dissipation effect of the lithium battery packaging structure through design, and improve the service life of the solid-state lithium battery.
