Description

Technical Field

[0001] The present application relates to the field of battery positive electrode sheets, and in particular to a high energy density hybrid sodium ion battery positive electrode sheet. Background Art

[0002] The positive electrode sheet is an electrode sheet with a high potential that contains active substances that undergo a reduction reaction during discharge. It is also called a positive electrode sheet. It is one of the key components in a sodium ion battery. It is composed of the positive electrode material of the sodium ion battery. The positive electrode sheet has good electrical conductivity and electrochemical activity. It plays an important role in storing and releasing sodium ions during the charging and discharging process of the sodium battery. The positive electrode sheet is usually composed of multiple composite layers, including positive electrode materials, conductive agents, binders and fillers. These layers are superimposed on each other through specific coating and molding processes to form a complete positive electrode sheet. The positive electrode sheet not only needs to have a high energy density and a long cycle life, but also needs to have good physical and chemical stability to ensure the safety and reliability of the sodium battery. When installing a conventional positive electrode sheet, the positive electrode sheet is installed at one end of the battery, and the surface of the positive electrode sheet is fixed to the battery with the help of a shielding tube, and a connecting sheet is installed between the positive electrode sheet and the battery, and the positive electrode sheet is connected to the battery with the help of the connecting sheet.

[0003] With respect to the above-mentioned related technologies, the inventors believe that when the positive electrode sheet is installed, it is often connected to the battery with the help of a shielding tube. When the shielding tube is loose, the positive electrode sheet is prone to be separated from the battery, causing the positive electrode sheet to lose its effect, resulting in inconvenience in the use of conventional positive electrode sheets.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0011] Preferably, an anti-separation block is fixedly mounted on one end of the fixing belt, and the size of the surface of the anti-separation block is larger than the size of the inner wall of the card slot.

The card block is installed on the surface of the positive electrode sheet, a fixing ring is installed at one end of the battery, a limiting groove is provided on the inner wall of the fixing ring, and the inner wall of the limiting groove is engaged with the surface of the card block, so that the positive electrode sheet and the battery can be connected with the help of the card block and the fixing ring, and the positive electrode sheet can be disassembled by separating the card block from the limiting groove.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1 —4 Provide further details of this application.

[0021] The present application discloses a high energy density hybrid sodium ion battery positive electrode sheet, referring to Figure 1 - Figure 2 , including a battery 1. During installation, the positive electrode sheet 2 is installed on one end of the battery 1. The surface of the positive electrode sheet 2 is fixed to the battery 1 by means of a shielding tube 3, and a connecting sheet 4 is installed between the positive electrode sheet 2 and the battery 1. The positive electrode sheet 2 is connected to the battery 1 by means of the connecting sheet 4, and a clamping block 5 is installed on the surface of the positive electrode sheet 2. A fixing ring 6 is installed at one end of the battery 1. A limiting groove 7 is provided on the inner wall of the fixing ring 6. The inner wall of the limiting groove 7 is clamped with the surface of the clamping block 5. The clamping block 5 and the fixing ring 6 connect the positive electrode sheet 2 to the battery 1, and the positive electrode sheet 2 can be disassembled by separating the clamping block 5 from the limiting groove 7, thereby avoiding the situation where the positive electrode sheet 2 is separated from the battery 1 due to the shielding tube 3, and effectively improving the stability of the positive electrode sheet 2 of the battery 1 after installation.

[0022] Reference Figure 2A shielding ring 9 made of rubber is installed on the surface of the positive electrode sheet 2. The surface of the shielding ring 9 is clamped with the connecting groove 10 in the fixing ring 6. The shielding ring 9 is kept connected to the fixing ring 6 by means of the connecting groove 10. The shielding ring 9 improves the sealing effect between the positive electrode sheet 2 and the fixing ring 6 to avoid the risk of electrolyte leakage in the battery 1. A limiting plate 8 is installed on the inner wall of the limiting groove 7. The card block 5 is fixed by means of the limiting plate 8, which effectively improves the stability of the device and prevents the card block 5 from escaping from the limiting groove 7. The limiting plate 8 structure is retractable to facilitate the card block 5 to be clamped in the limiting groove 7.

[0023] Reference Figure 3 - Figure 4 , the pulling rod 11 is installed on the surface of the connecting piece 4, and fixing belts 12 are installed at both ends of the pulling rod 11. The surface of the fixing belt 12 is engaged with the card slot 14 in the positive electrode sheet 2, and the pulling rod 11 is fixed with the help of the fixing belt 12. After the two fixing belts 12 are pulled, the pulling rod 11 between the two fixing belts 12 squeezes the connecting piece 4, and the surface of the connecting piece 4 is kept connected to one end of the battery 1, effectively ensuring the state of connection between the connecting piece 4 and the battery 1, avoiding the situation that the connecting piece 4 is fixed by its own elasticity, and the elastic effect of the connecting piece 4 deteriorates after being placed for a long time, resulting in the connection piece 4 and one end of the battery are separated, and the surface of the fixing belt 12 is connected to the inner wall of the shielding tube 3 to ensure the overall sealing of the battery 1, and one end of the fixing belt 12 is fixedly installed with an anti-separation block 13, and one end of the fixing belt 12 is limited by the anti-separation block 13, avoiding the situation that the two ends of the fixing belt 12 enter the battery 1, which makes it difficult for the user to adjust the position of the pulling rod 11.

[0024] The implementation principle of a high energy density hybrid sodium ion battery positive electrode sheet in the embodiment of the present application is as follows: by installing a clamping block 5 on the surface of the positive electrode sheet 2, a fixing ring 6 is installed at one end of the battery 1, and a limiting groove 7 is provided on the inner wall of the fixing ring 6. The inner wall of the limiting groove 7 is clamped with the surface of the clamping block 5, so that the positive electrode sheet 2 and the battery 1 can be connected with the help of the clamping block 5 and the fixing ring 6, and the positive electrode sheet 2 can be disassembled by separating the clamping block 5 from the limiting groove 7. A shielding ring 9 made of rubber is installed on the surface of the positive electrode sheet 2, and the surface of the shielding ring 9 is clamped with the connecting groove 10 in the fixing ring 6, so that the sealing effect between the positive electrode sheet 2 and the fixing ring 6 can be improved with the help of the shielding ring 9 to avoid the risk of electrolyte leakage in the battery 1. A limiting plate 8 is installed on the inner wall of the limiting groove 7, so that the clamping block 5 can be fixed with the help of the limiting plate 8, which effectively improves the stability of the device and prevents the clamping block 5 from detaching from the limiting groove 7.

[0025] The pulling rod 11 can also be installed on the surface of the connecting piece 4, and fixing belts 12 are installed at both ends of the pulling rod 11. The surface of the fixing belt 12 is engaged with the card slot 14 in the positive electrode sheet 2, so that the pulling rod 11 can be fixed with the help of the fixing belt 12, so that the pulling rod 11 keeps the connecting piece 4 connected to one end of the battery 1, effectively ensuring the connection state of the connecting piece 4 and the battery 1. An anti-separation block 13 is fixedly installed on one end of the fixing belt 12, so that one end of the fixing belt 12 can be limited by the anti-separation block 13, thereby avoiding the situation where the two ends of the fixing belt 12 enter the battery 1, which makes it difficult for the user to adjust the position of the pulling rod 11.
