Description

Technical Field

[0001] This utility model belongs to the field of battery technology, specifically relating to a cylindrical sodium-ion solid-state battery. Background Technology

[0002] A cylindrical sodium-ion solid-state battery is a type of secondary battery that uses a solid electrolyte and sodium ions (Na+) as the charge carrier.

[0003] Currently, cylindrical sodium-ion solid-state batteries are typically used by placing them in the battery slot within a battery case. However, existing cylindrical sodium-ion solid-state batteries have the following drawbacks during use:

[0004] After the battery is removed, its circular shape makes it difficult to place stably on a flat surface, making it prone to rolling and breaking. Secondly, when the battery is installed in the battery slot, the width of the slot is generally larger than the diameter of the battery, so the battery is easily unstable in the slot and tends to wobble from side to side, which affects the connection stability of the electrodes at both ends. Therefore, a cylindrical sodium-ion solid-state battery is needed. Utility Model Content

[0005] The purpose of this invention is to provide a cylindrical sodium-ion solid-state battery to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical sodium-ion solid-state battery, comprising a battery body installed in a battery slot within a battery case, wherein two symmetrically arranged anti-roll positioning components are installed on the outer side of the battery body; the anti-roll positioning components are used, on the one hand, to prevent the battery body from rolling when placed on a supporting plane body, and on the other hand, to firmly fix the battery body in the battery slot.

[0007] In a preferred embodiment, the anti-roll positioning assembly includes a C-shaped clamp sleeved on the outside of the battery body, and a first weakening groove is formed in the middle of the inner side of the C-shaped clamp.

[0008] In one preferred embodiment, the bottom two sides of the C-shaped clamp are integrally formed with inclined portions.

[0009] In a preferred embodiment, two symmetrically arranged U-shaped abutment plates are fixed to the outer arc wall of the C-shaped clamp, and a second weakening groove is provided at the bend of the inner middle of each U-shaped abutment plate.

[0010] In a preferred embodiment, the vertical height of the end of the U-shaped clamping plate away from the C-shaped clamping plate is smaller than the vertical height of the middle part of the outer arc wall of the C-shaped clamping plate.

[0011] In a preferred embodiment, the two U-shaped clamping plates and the C-shaped clamping plate are integrally provided with the same lightweight groove.

[0012] Compared with the prior art, the cylindrical sodium-ion solid-state battery provided by this utility model has at least the following beneficial effects:

[0013] In this invention, when using the cylindrical sodium-ion solid-state battery, firstly, a C-shaped clamp is fitted onto the outside of the battery body. With the addition of two inclined sections, the C-shaped clamp, when lowered and fitted onto the outside of the battery body, is stretched open by the first weakening groove and clamped securely to the outside of the battery body. Then, the battery body with the two anti-roll positioning components installed is inserted into the battery slot. The U-shaped abutment plates on both side walls, combined with the second weakening groove, cause the U-shaped abutment plates to deform under pressure, ensuring the stability of the battery body within the battery slot and preventing lateral wobbling after installation that could lead to unstable electrode connections. Simultaneously, the deformation of the U-shaped abutment plates further strengthens the clamping force of the C-shaped clamp on the battery body. Furthermore, after the battery body is removed, the overall shape of the anti-roll positioning components is W-shaped, preventing the battery body from rolling off and breaking when placed on a flat surface.

[0019] The present invention will be further described below with reference to the embodiments.

[0022] Example

[0023] Currently, cylindrical sodium-ion solid-state batteries are generally placed in the battery slot 11 within the battery case 1 for use. However, existing cylindrical sodium-ion solid-state batteries have the following drawbacks during use:

[0024] After the battery is removed, its circular shape makes it difficult to place it stably on a flat surface, making it prone to rolling and breaking. Secondly, after the battery is installed in the battery slot 11, since the width of the battery slot 11 is generally larger than the diameter of the battery, the battery is prone to being unstable in the battery slot 11 and tends to sway from side to side, thus affecting the connection stability of the electrodes at both ends.

[0025] For this purpose, please refer to Figure 1-4 This utility model provides a cylindrical sodium-ion solid-state battery, including: a battery body 13 installed in a battery slot 11 inside a battery box 1, and two symmetrically arranged anti-roll positioning components 2 installed on the outside of the battery body 13; the anti-roll positioning components 2 are used to prevent the battery body 13 from rolling when placed on the supporting plane body, and to firmly fix the battery body 13 in the battery slot 11.

[0026] A partition 12 is also fixedly connected to the battery compartment 11, which divides the battery box 1 into two battery compartments 11.

[0027] Further as Figure 1-4As shown, it is worth noting that, in order to prevent the battery body 13 from rolling when it is removed from the battery slot 11 and placed on the flat body, and to ensure that the battery body 13 is firmly fixed in the battery slot 11 and does not wobble from side to side, thus affecting the stability of the electrode connection, an anti-roll positioning component 2 is provided. This component includes a C-shaped clamp 21 sleeved on the outside of the battery body 13. A first weakening groove 22 is provided in the middle of the inner side of the C-shaped clamp 21. Inclined portions 23 are integrally formed on both sides of the bottom end of the C-shaped clamp 21. Two symmetrically arranged U-shaped abutment plates 24 are fixed on the outer arc wall of the C-shaped clamp 21. A second weakening groove 25 is provided at the bend in the middle of the inner side of the U-shaped abutment plates 24. The vertical height of the U-shaped abutment plates 24 away from the C-shaped clamp 21 is smaller than the vertical height of the middle of the outer arc wall of the C-shaped clamp 21. The same lightweight groove 26 is integrally formed on the two U-shaped abutment plates 24 and the C-shaped clamp 21.

[0028] Among them, all components of the anti-roll positioning assembly 2 are made of ABS plastic, which has low manufacturing cost and can be injection molded in one piece.

[0029] In summary: When using this cylindrical sodium-ion solid-state battery, firstly, the C-shaped clamp 21 needs to be fitted onto the outside of the battery body 13. With the two inclined portions 23, when the C-shaped clamp 21 is lowered and fitted onto the outside of the battery body 13, the first weakening groove 22 allows the C-shaped clamp 21 to be opened and clamped and fixed to the outside of the battery body 13. Then, the battery body 13, with the two anti-roll positioning components 2 installed, is inserted into the battery slot 11. This is aided by the U-shaped clamping plates 24 on both side walls, and simultaneously by the second weakening groove 25. The U-shaped clamping plate 24 is compressed and deformed, which ensures the stability of the battery body 13 in the battery slot 11 and prevents it from wobbling left and right after installation, thus preventing unstable electrode connection. At the same time, the compression and deformation of the U-shaped clamping plate 24 makes the clamping force of the C-shaped clamping plate 21 on the battery body 13 more secure. Furthermore, after the battery body 13 is removed, the overall shape of the anti-roll positioning component 2 is arranged in a W-shape, so that when the battery body 13 is placed on the flat surface, it is less likely to roll off and break.
