[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 A coated cover plate with ion conductivity includes a glass cover plate body 1, two corners of which are designed to be rounded, and a coating layer 2 is provided on the top surface of the glass cover plate body 1. The coating layer 2 is composed of a glass contact layer 201, an intermediate layer 202, and a top surface layer 203; the glass contact layer 201, the intermediate layer 202, and the top surface layer 203 are sequentially stacked on the glass cover plate body 1 in a coating manner, and the overall thickness of the coating layer 2 is thinner than that of the glass cover plate body 1, and the thickness of the coating layer 2 composed of the glass contact layer 201, the intermediate layer 202, and the top surface layer 203 are different.

[0024] See also Figure 1-2 In this embodiment, the glass contact layer 201 is plated on the top surface of the glass cover body 1 , and the glass contact layer 201 is made of silicon dioxide material; the thickness of the glass contact layer 201 is between fifty nanometers and eighty nanometers.

[0025] Specifically, the glass contact layer 201 serves as a substrate, providing good adhesion and chemical stability to the glass cover plate body 1 .

[0026] See also Figure 1-2 In this embodiment, the intermediate layer 202 is plated on the top surface of the glass contact layer 201 , and the intermediate layer 202 is made of lithium phosphate material.

[0027] Specifically, the intermediate layer 202 is used to provide specific electrical or optical properties, such as ionic conductivity, and its thickness can be between tens of nanometers and several micrometers according to specific requirements.

[0028] See also Figure 1-2 In this embodiment, the top surface layer 203 is plated on the top surface of the intermediate layer 202 and forms the outer surface. The top surface layer 203 is made of lithium carbonate material. The thickness of the top surface layer 203 is between eight nanometers and eighteen nanometers.

[0029] Specifically, the top surface layer 203 is used to provide additional chemical stability.

[0030] See also Figure 1-3 In this embodiment, the sizes of the glass contact layer 201 , the intermediate layer 202 and the top surface layer 203 are the same and are the same as the size of the glass cover plate body 1 .

[0031] Specifically, when the sizes are the same, the areas of the glass contact layer 201, the intermediate layer 202 and the top surface layer 203 on the glass cover plate body 1 are the same, so it can be ensured that the glass contact layer 201, the intermediate layer 202 and the top surface layer 203 are regularly plated on the glass cover plate body 1.

[0032] See also Figure 1-3 In this embodiment, when the glass contact layer 201, the intermediate layer 202 and the top surface layer 203 are sequentially plated on the glass cover body 1, the side surfaces of the glass contact layer 201, the intermediate layer 202 and the top surface layer 203 are all in the same plane as the side surfaces of the glass cover body 1.

[0033] Specifically, when the side surfaces of the glass contact layer 201 , the middle layer 202 and the top layer 203 are all in the same plane as the side surfaces of the glass cover plate body 1 , it is possible to avoid the situation where each layer is of different sizes or the film overflows, thereby ensuring the integrity of the coating layer 2 .

[0034] In summary, the solution of this application has the following functions:

[0035] 1. Chemical stability:

[0036] Both silicon dioxide and lithium phosphate have good chemical stability and can resist corrosion from chemical substances such as acid and alkali, thereby protecting the glass cover plate body 1 . Meanwhile, the top surface layer 203 composed of lithium carbonate can further enhance the chemical stability of the coating layer 2 .

[0037] 2. Optical performance:

[0038] The intermediate layer 202 composed of lithium phosphate can be adjusted as needed to achieve specific optical properties, such as refractive index adjustment, thereby improving the light transmittance of the glass cover plate body 1 or achieving a specific filtering effect.

[0039] 3. Electrical properties:

[0040] The intermediate layer 202 composed of lithium phosphate may have ion conductivity under certain conditions, which provides the possibility for the glass cover body 1 to be used in specific electrical applications (such as batteries or sensors).

[0041] 4. Adhesion and durability:

[0042] The glass contact layer 201 composed of silicon dioxide serves as a substrate and has good adhesion to the glass cover plate body 1 , thereby ensuring the stability and durability of the coating layer 2 .

[0043] At the same time, the coating layer 2 on the glass cover plate body 1 proposed in this patent adopts a layered structure design, which is composed of a glass contact layer 201, an intermediate layer 202 and a top surface layer 203. The glass contact layer 201 uses silicon dioxide (SiO2) as a substrate. Because it has good adhesion and chemical stability with the glass cover plate body 1, it can effectively ensure the stability and durability of the coating layer 2. The intermediate layer 202 uses lithium phosphate (Li3PO4). This material has ion conductivity under certain conditions and can provide ion conductivity for the glass cover plate body 1 in electrical applications (such as batteries or sensors). At the same time, lithium phosphate ( Li3PO4) can also be adjusted as needed to achieve specific optical properties, such as refractive index adjustment, thereby improving the light transmittance of the glass cover body 1 or achieving a specific filtering effect. The top surface layer 203 uses lithium carbonate (Li2CO3), which has excellent chemical stability and can further enhance the chemical stability of the coating layer 2. By precisely controlling the thickness and combination of each layer, the coating layer 2 on the glass cover body 1 achieved by this patent not only has excellent chemical stability and optical properties, but also has good electrical properties and adhesion, which can meet the high performance requirements of glass cover plates in different fields.
