Description

Technical Field

[0001] The utility model relates to the field of paint coatings, in particular to an improved power generation paint coating. Background Art

[0002] Power-generating coatings are a special type of functional coating that has emerged in recent years. By coating the surface of a substrate that is not conductive, it gives the object a certain ability to conduct and eliminate static electricity, while also preventing electromagnetic radiation. However, in actual applications, conductive coatings have problems such as insufficient environmentally friendly power generation, poor durability, and difficulty in storing electricity, and have not attracted much attention.

At the same time, in the prior art, the current collectors are respectively located in the upper and lower parts of the solid electrolyte layer. Such a design does not better collect the carriers formed on the positive and negative electrode surfaces during the charging and discharging process. Utility Model Content
