Abstract

The invention relates to a preparation method of a flexible integral solar battery / lithium-ion battery thin-film composite battery, and belongs to the technical field of electric energy. According to the preparation method of the flexible integral solar battery / lithium-ion battery thin-film composite battery, a same flexible thin-film substrate is adopted; a solar battery and a lithium-ion battery are located at the front surface and the back surface of the flexible thin-film substrate respectively; and the method comprises the following preparation processes: (1) preparing a flexible thin-film solar battery; and (2) preparing a flexible thin-film solar battery / lithium-ion battery integrated battery, protecting one side of the solar battery with a mask, integrally sputtering an aluminum film on the other side and coating the other side with a positive electrode material layer; coating a PI / Cu composite thin-film with a negative electrode material layer and forming a whole body in a hot pressing manner; and adding a flexible lithium-ion battery to an electrolyte, integrally encapsulating the battery and connecting the flexible thin-film solar battery and the flexible thin-film lithium-ion battery to a flexible power controller respectively. The preparation method has the advantages of being stable in process, convenient to operate and the like; and the product is a real flexible integral battery, is light in weight, convenient to carry and high specific energy, and can adapt to different installation surfaces.

Description

technical field [0001] The invention belongs to the technical field of electric energy, and in particular relates to a preparation method of a flexible integrated solar battery / lithium ion battery film composite battery. Background technique [0002] At present, the flexible integrated solar battery / lithium-ion battery thin-film composite battery is a new type of power supply, which is flexible, can adapt to different installation surfaces, and is easy to carry. It uses thin-film solar cells to charge lithium batteries, so it has a self-charging function. It can power electronic equipment for a long time and over a long distance. [0003] The known solar cell / lithium battery integrated power system consists of solar cells, storage batteries and power controllers, wherein the solar cells, storage batteries and power controllers are all non-flexible rigid structures or only the solar cells are flexible structures. The solar cell in the patent CN103280846A "A Flexible Photovol...
