DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 In an embodiment of the utility model, a lithium battery storage device comprises a storage seat 1, wherein a plurality of accommodating cavities 2 are provided inside the storage seat 1, and the accommodating cavities 2 are used to place lithium batteries, a dehumidification cavity 3 is provided inside the storage seat 1, a plurality of connecting channels 4 are provided inside the dehumidification cavity 3, and the plurality of connecting channels 4 are respectively connected to the plurality of accommodating cavities 2, a detachable dehumidification box 5 is provided in the dehumidification box 5, and a dehumidification material is loaded inside the dehumidification box 5, a plurality of dehumidification through holes 6 are provided on the outer edge of the dehumidification box 5, and the dehumidification through holes 6 are connected to the interior of the dehumidification box 5 and the dehumidification cavity 3, a detachable top cover 8 is provided on the top of the storage seat 1, a connecting groove 11 connecting to the dehumidification cavity 3 is provided inside the top cover 8, a fixed top ring 12 is provided on the top of the top cover 8, the interior of the fixed top ring 12 is connected to the connecting groove 11, a fixed inner ring 13 is provided inside the fixed top ring 12, and the fixed inner ring 13 is elastic, and a fixing column 7 is provided on the top of the dehumidification box 5, and the fixing column 7 is snap-connected with the interior of the fixed inner ring 13.

[0022] It can be understood that when the lithium battery is placed in the accommodating cavity 2 for storage, since the dehumidification through hole 6 connects the interior of the dehumidification box 5 and the dehumidification cavity 3, the dehumidification cavity 3 connects multiple connecting channels 4, and the multiple connecting channels 4 respectively connect multiple accommodating cavities 2, the dehumidification box 5 loaded with dehumidification material inside allows the moisture in the accommodating cavity 2 to be absorbed by the dehumidification material of the dehumidification box 5, thereby reducing the moisture in the accommodating cavity 2 and preventing the lithium battery from getting damp.

[0023] In addition, when the adsorption material is fully adsorbed, the fixing column 7 is pulled to separate the fixing column 7 from the fixing inner ring 13, thereby facilitating replacement of the adsorption material of the dehumidification box 5.

[0024] An installation cavity 9 is provided at the bottom of the top cover 8 , and a fixed outer ring 10 is provided at the outer edge of the storage seat 1 . The fixed outer ring 10 is elastic, and the installation cavity 9 is sleeved on the top of the storage seat 1 so that the outer edge of the fixed outer ring 10 abuts against the inner edge of the installation cavity 9 .

[0025] A first insulating sheet 14 is disposed at the bottom of the accommodating cavity 2 , and a plurality of second insulating sheets 15 are disposed inside the mounting cavity 9 . The plurality of second insulating sheets 15 are respectively inserted into the tops of the plurality of accommodating cavities 2 .

[0026] It can be understood that the two electrodes of the lithium battery are in contact through the first insulating sheet 14 and the second insulating sheet 15, so as to prevent the lithium battery from being energized by the conductive material, thereby extending the service life of the lithium battery.

[0027] The first insulating sheet 14 and the second insulating sheet 15 are made of plastic.

[0028] It is understandable that plastics have good electrochemical stability and do not react with the chemicals in the battery, so they can effectively block the flow of current and thus prevent the internal short circuit of the lithium battery.

[0029] The material of the fixed outer ring 10 and the fixed inner ring 13 is rubber.

[0030] It can be understood that the most notable feature of rubber is that it can deform under the action of external force and return to its original shape after the external force is removed, so that the top cover 8 is fixed on the dehumidifier seat, the fixing column 7 is fixed in the fixed top ring 12, and the elasticity of the rubber enables it to fill and adapt to the tiny irregularities of the joint surface, forming an effective seal for the inner ring of the fixed top ring 12 and the installation cavity 9.

[0031] The dehumidifying material is calcium chloride.

[0032] It is understandable that calcium chloride can absorb moisture because it has strong hydrophilicity, that is, it can interact with water molecules and absorb water to form hydrates. For example, calcium chloride hexahydrate is the product of calcium chloride and water molecules. These water molecules are fixed in the crystal structure of calcium chloride, thereby reducing the humidity of the accommodating cavity 2.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
