Abstract
The present invention discloses a printing-type flexible electrolytic capacitor and a manufacturing method thereof. The printing-type flexible electrolytic capacitor comprises a flexible anode support substrate, an anode formed by printing low-melting-point metal ink onto the anode substrate, an insulating layer dielectric medium formed after oxidization of an anode metal thin film by an electrolysis process, an electrolyte serving as a cathode, and a flexible cathode support substrate. According to the printing-type flexible electrolytic capacitor and the manufacturing method thereof, the low-melting-point metal ink and the electrolysis process are introduced to manufacture an oxide insulating layer, and thus the printing-type flexible electrolytic capacitor can be directly manufactured in a printing manner; the printing substrate adopts a flexible substrate, and thus a wearable high-capacity capacitor battery can be manufactured; requirements of the whole manufacturing process for environment is not high, and the whole manufacturing process can be completed under room temperature and normal conditions, thereby notably reducing the complexity of the manufacturing technique of the electrolytic capacitor, greatly raising manufacturing efficiency and lowering costs.
Description
Technical field
The present invention relates to electric capacity manufacture technology field, the flexible electrochemical capacitor of a kind of printing-type particularly realized by means of low-melting-point metal printing coating and cell reaction mode and manufacture method.
Background technology
Electric capacity is the device holding electric charge, any two insulated from each other and be separated by between very near conductor and all can form a capacitor.Electric capacity has extensive use in the electronic device, is usually used in energy storage, control, and every aspects such as straight-through friendship, coupling, bypass, filtering, resonant tanks in circuit.Wherein, accumulation energy type capacitor collects electric charge by rectifier, and the energy of storage is sent to the output of power supply by converter lead-in wire, serves as a kind of battery thus.According to different power requirements, capacitor can adopt the mode such as series, parallel or its combination.Electric charge can be stored under capacitor alive effect outside.Owing to being a kind of physical property energy storage device, electric capacity has charging interval short, the advantage such as power output is high, the life-span is long.
In various electric capacity, electrochemical capacitor is that a kind of unit volume capacity can exceed the tens of electric capacity arriving hundreds of times of conventional capacitance, and cost is lower, thus has extensive use.Common electrolytic capacitor adopts aluminium or tantalum metal forming as positive pole, and using the insulating oxide of metal forming as dielectric, negative electrode is then made up of jointly electric conducting material, electrolyte etc., and because electrolyte is the major part of negative electrode, therefore electrochemical capacitor gains the name.So far, due to restriction and the process characteristic of manufactured materials, this type of electric capacity is generally presented as rigid structure.
Current electrochemical capacitor can realize production mechanization and the automation of scale.Wherein, aluminium electrolytic capacitor is mainly made according to corrosion and two-step process of energizing mutually.Wherein, etching process is dependent on paper tinsel speed and power supply type, voltage etc. in corrosive liquid kind, concentration, temperature, former paper tinsel composition, structure, surface state, corrosion process and carries out; Energize technique then for the manufacture of dielectric oxide film.Due to these factors, traditional electrochemical capacitor facility investment is large, and manufacture process is usually very complicated, power consumption water consumption, and certain environment can be caused to pollute, and due to process technology limit, this kind of electrochemical capacitor is difficult to make flexible and collapsible device.In recent years, along with a large amount of novel flexible electronic installation comprises the appearance of wearable device, to the demand sharp increase of flexible battery.For this reason, if whole manufacture crafts of electrochemical capacitor can be developed into printing-type, be then expected to realize flexible electric capacity and even battery, and greatly can simplify the cost of manufacture of electrochemical capacitor, thus meet growing demand.But the conductive ink that can present with fluid state at present extremely lacks, and in electrochemical capacitor, electrolyte thickness not easily makes very thin usually, thus seriously can restrict the capacity of formed electrochemical capacitor.For this reason, need to seek feasible way from new technical concept.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is, the deficiency of directly printing thus more difficult formation flexible device is not easily realized for existing electrochemical capacitor manufacturing technology, introduce low-melting-point metal ink and ultrathin insulating layer electrolyte electrolysis process thereof, the flexible electrochemical capacitor of a kind of printing-type and manufacture method are provided, the flexibility that the quick manufacture of corresponding device, significantly hoist capacity and even technology use can be guaranteed.
