Power generation and energy storing integrated battery and manufacturing method thereof

Abstract

The invention discloses a power generation and energy storing integrated battery which comprises a photovoltaic power generating unit and an energy storage unit. The photovoltaic power generating unitand the energy storage unit are layer-shaped and abut against each other for forming an integrated structure. The abutting surface between the photovoltaic power generating unit and the energy storage unit forms a common cathode. The other surface of each of the photovoltaic power generating unit and the energy storage unit is provided with a corresponding anode. The battery according to the invention has advantages such as small size and small weight. The invention further discloses a battery manufacturing method which comprises the steps of S01, depositing a film on the abutting surface between the photovoltaic power generating unit and the energy storage unit, thereby forming the cathode of the energy storage unit; S02, printing the cathode of the photovoltaic power generating unit ona film, wherein the film and the printed cathode form a common cathode, and printing an anode on the other surface of the photovoltaic power generating unit; and S03, applying an insulating paint on the film, depositing a solid electrolyte film, and depositing an anode film on the solid electrolyte film for forming the anode of the energy storage unit. The method of the invention has advantages such as simple operation.

Description

technical field [0001] The invention mainly relates to the technical field of solar cells, in particular to an integrated battery for power generation and energy storage and a manufacturing method thereof. Background technique [0002] With the development of artificial intelligence, smart devices such as various sensor network nodes, smart microsystems, and wearable electronic devices continue to emerge, such as electronic skins, smart bracelets, etc., which have shown great potential. However, due to the random and scattered application scenarios and locations of smart devices, they cannot be connected to the mains grid. At the same time, the devices are limited in size and the battery life of energy storage is short, so the application is limited. [0003] The current conventional strategy is to use the solar battery and the energy storage battery as two independent units and connect them through wires, and integrate them into smart devices respectively. Power the smart ...

AI Technical Summary

Problems solved by technology

The solar cell and the energy storage battery are connected by wires as two independent units, and the external wires will cause power loss

Therefore, such a system often needs to occupy a relatively large space, which limits its application in micro-miniature smart devices.

Therefore, the existing solar battery and lithium-ion battery energy storage systems have the disadvantages of relatively low energy density and large volume. application
