Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a printed flexible capacitor by introducing low-melting point metal ink and its ultra-thin insulating layer electrolyte electrolysis process in view of the fact that the existing electrolytic capacitor manufacturing technology is not easy to realize direct printing and thus it is difficult to form flexible devices. Electrolytic capacitors and manufacturing methods can ensure rapid manufacturing of corresponding devices, significantly increase capacity and even flexibility in technical use

Embodiment 1

[0054] figure 2 As shown, it is a schematic structural diagram of the printed flexible electrolytic capacitor according to Embodiment 1 of the present invention. In this embodiment, the flexible anode supporting substrate 1 is coated paper with a thickness of 5cm*5cm*0.05mm, and the liquid gallium conductive metal ink containing 0.25wt% gallium oxide is printed and coated in the form of a thin film on this substrate, forming a thickness of A 0.1 mm conductive film 2 is drawn out with a conventional copper wire at the end of the electrode film as a subsequent capacitor anode terminal 3 . Spray water on the surface of the above-mentioned film 2 to form a water film with a thickness of about 1mm. On this water film, a copper metal sheet is attached as a cathode. Electrolytic reaction, in which the oxygen gas produced at the anode of the gallium film anode partly oxidizes the shallow surface of the gallium film on the anode, thus forming a thin layer of gallium oxide insulating ...

Abstract

The invention discloses a printed flexible electrolytic capacitor and a manufacturing method thereof. The printed flexible electrolytic capacitor comprises: a flexible anode support base, an anode made of low melting point metal ink printed on the anode base, and a metal film for the anode The insulating layer dielectric formed after oxidation by an electrolytic process, the electrolyte acting as a cathode, and a flexible cathode support substrate. In the printed electrolytic capacitor and the manufacturing method of the present invention, since the low melting point liquid metal ink and the electrolytic process are introduced to manufacture the oxide insulating layer, the entire printed electrolytic capacitor can be directly manufactured by printing, and the printed substrate adopts a flexible substrate, It can be made into a wearable large-capacity capacitor battery; the entire production process does not require high environmental requirements and can be completed under normal temperature and normal conditions, thus significantly reducing the complexity of the electrolytic capacitor preparation process, greatly improving its production efficiency and reducing cost.

Description

technical field [0001] The invention relates to the technical field of capacitor manufacturing, in particular to a printed flexible electrolytic capacitor and a manufacturing method realized by means of low melting point metal printing coating and electrolytic reaction. Background technique [0002] A capacitor is a device used to hold charges, and a capacitor can be formed between any two conductors that are insulated from each other and very close to each other. Capacitors are widely used in electronic equipment, and are often used in energy storage, control, and circuit isolation, coupling, bypass, filtering, and tuning circuits. Among them, the energy storage capacitor collects the charge by means of a rectifier and transfers the stored energy to the output terminal of the power supply through the converter lead, thus acting as a kind of battery. According to different power requirements, capacitors can be connected in series, in parallel or in combination. Capacitors ...
