[0027] The above-mentioned substrate with a deoxidizer layer is cut and made into a battery cover shell, which includes a first cover body 2 and a second cover body 3. Two sets of positioning blocks 4 are arranged on both side walls of the second cover body 3. A gas injection pipe 9 is arranged on one side wall of the first cover body 2. An exhaust pipe 10 is arranged on one side of the gas injection pipe 9. The exhaust pipe 10 is arranged on the side wall of the first cover body 2. The two cover bodies correspond to the cover box to form a cavity, and the gas injection pipe 9 and the exhaust pipe 10 are formed to form an oxygen-isolating battery cover for gas injection and oxygen discharge operations. The deoxidizer layer is made of deoxidized thermal insulation material.

[0028] Two groups of positioning blocks 4 are arranged on both side walls of the second cover body 3, and a group of first screw holes 5 are arranged on the upper end surfaces of the multiple groups of positioning blocks 4. Two groups of mounting blocks 6 are arranged on both side walls of the first cover body 2, and a group of second screw holes 7 are arranged on the multiple groups of mounting blocks 6. Multiple groups of mounting bolts 8 are arranged inside the multiple groups of first screw holes 5 and second screw holes 7. An air injection pipe 9 is arranged on one side wall of the first cover body 2, and an exhaust pipe 10 is arranged on one side of the air injection pipe 9. The exhaust pipe 10 is arranged on the side wall of the first cover body 2; the diameters of the first screw hole 5 and the second screw hole 7 are the same, and the first screw hole 5 and the second screw hole 7 are used in conjunction with the mounting bolts 8, and the inner surfaces of the first cover body 2 and the second cover body 3 are provided with a deoxidizer layer.

[0029] Specifically, the second screw hole 7 is arranged directly above the first screw hole 5, and the mounting bolt 8 is installed inside the first screw hole 5 and the second screw hole 7, so that the battery assembly 1 can be installed inside the first cover body 2 and the second cover body 3; gas other than oxygen is injected into the first cover body 2 and the second cover body 3 through the gas injection pipe 9, and the air existing in the first cover body 2 and the second cover body 3 is discharged, so that the battery assembly 1 can be arranged inside the first cover body 2 and the second cover body 3, and the battery assembly 1 can be placed in an oxygen-free state. At the same time, the deoxidizer layer 17 can further deoxidize the interior of the first cover body 2 and the second cover body 3, thereby increasing the possibility of avoiding fire of the battery assembly 1.

[0030] like Figure 1-Figure 2 As shown, two groups of support blocks 11 are arranged on the front and rear end walls of the second cover body 3, a group of limit blocks 12 are arranged on the upper end surfaces of the multiple groups of support blocks 11, and a group of limit frames 13 are arranged on the upper ends of the multiple groups of limit blocks 12; the multiple groups of limit frames 13 are respectively arranged on the front and rear end walls of the first cover body 2; by setting the limit blocks 12 and the limit frames 13, the first cover body 2 can be limited to the upper end of the second cover body 3, so as to facilitate the fixing of the first cover body 2 and the second cover body 3.

[0031] like Figure 1-Figure 4 As shown, the inner surfaces of the first cover body and the second cover body are provided with a deoxidizer layer, both of which include a base plate 14, and multiple groups of inner walls of the base plate 14 are provided with frame plates 15; multiple groups of frame plates 15 are provided with multiple groups of grooves 16, and multiple groups of grooves 16 are provided with a group of deoxidizer layers 17 inside, and multiple groups of deoxidizer layers 17 are arranged on the side walls of the base plate 14; the deoxidizer layer 17 is made of deoxidizer, which is also made of deoxidizer thermal insulation material, which belongs to existing materials and is currently mostly used for deoxidation and preservation of food. When there is still a surplus or leakage in the internal oxygen content of the first cover body 2 and the second cover body 3, multiple groups of deoxidizer layers 17 are used to remove the oxygen in the first cover body 2 and the second cover body 3, which is relatively practical.

[0032] The above is also a deoxygenating battery cover, that is, it includes a deoxygenating component, which is used to deoxygenate the battery assembly 1. The deoxygenating component is arranged on the outside of the battery assembly 1. The deoxygenating component includes a first cover body 2, which is arranged above the battery assembly 1. The lower end of the first cover body 2 is provided with a second cover body 3, and the second cover body 3 is arranged on the outside of the battery assembly 1.

[0033] When in use, the battery assembly 1 is placed inside the first cover body 2 and the second cover body 3, and then the first cover body 2 can be limited to the upper end of the second cover body 3 by the limit block 12 and the limit frame 13, so that the second screw hole 7 is set directly above the first screw hole 5, and then the mounting bolt 8 is installed inside the first screw hole 5 and the second screw hole 7, so that the battery assembly 1 can be installed inside the first cover body 2 and the second cover body 3; the first cover body 2 and the second cover body 3 are filled with gases other than oxygen through the gas injection pipe 9 connected to the external gas pipe, and the air existing in the first cover body 2 and the second cover body 3 is discharged. During actual exhaust, a nitrogen gas injection device can be used, and the first cover body 2 and the second cover body 3 are filled with only nitrogen gas, thereby making them oxygen-free; when the internal oxygen content of the first cover body 2 and the second cover body 3 still has a surplus or leaks, multiple groups of deoxidizer layers 17 are continuously used to remove the oxygen in the first cover body 2 and the second cover body 3, which is more practical. The externally connected gas injection device is not described in detail. The existing gas injection device can be used to inject gas and exhaust oxygen. After the gas is injected and exhausted, the gas injection pipe 9 and the exhaust pipe 10 can be blocked.

[0034] A deoxygenating battery cover is realized by a processing method of an oxygen-isolating battery cover, so that the battery cover can not only protect the battery but also realize the functions of deoxygenation and oxygen isolation. By arranging a gas injection pipe, an exhaust pipe and a positioning block, the battery assembly is effectively arranged inside a first cover body and a second cover body, and gas injection and oxygen removal operations can be realized, so that the internal battery assembly can be in an oxygen-free state. At the same time, the interior of the first cover body and the second cover body can be continuously deoxygenated by the arranged deoxygenator layer, thereby increasing the possibility of avoiding fire of the internal battery assembly after installation and use.
