Abstract
The invention provides a flat electrolytic capacitor comprising an outer shell, an anode, electrolyte, a cathode, an anode pin and a cathode pin, wherein the anode, the electrolyte and the cathode are arranged on a plane in a laminated mode. Distinguished from a method that an anode, electrolyte and a cathode in the prior art are wound, the flat electrolytic capacitor solves the problem that an existing electrolytic capacitor is large in thickness. The electrolytic capacitor can be manufactured in a square shape or a slice shape, a traditional cylindrical structure is changed, and therefore the electrolytic capacitor is particularly suitable for electronic products requiring the small thickness of the electrolytic capacitor, and has wide application prospects.
Description
Technical field
The present invention relates to a kind of electrochemical capacitor, is a kind of electrolytic capacitor with flat shape or square shape that is different from existing cylindrical shape electrolytic capacitor.
Background technology
Electrolytic capacitor is a kind of of electric capacity, metal forming is anodal (aluminium or tantalum), the oxide-film (aluminium oxide or tantalum pentoxide) of being close to metal with positive pole is dielectric, negative electrode is by electric conducting material, electrolyte (electrolyte can be liquid or solid) and other materials form jointly, electrochemical capacitor extensively is used in and does filter element and energy-storage travelling wave tube use in the electronic circuit, its advantage is that capacity is large, present electrochemical capacitor mainly is anodal, dielectric, negative electrode forms by coiling, so volume and highly all larger, not very large at some to capacity requirement, but the occasion very high to thickness requirement, such as the power supply of part flat lamp, just can't use existing electrochemical capacitor, the paster electrochemical capacitor is also arranged on the market, but it is highly also not little, is difficult to use in interior electronic circuit 2 millimeters of required thicknesses.
Summary of the invention
Large in order to overcome existing electrochemical capacitor thickness, can not be used for some shortcoming to the high occasion of thickness requirement, the present invention proposes a kind of plane electrolytic capacitor.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of plane of the present invention electrolytic capacitor, formed by shell, anode, electrolyte, negative electrode, anode leading foot, negative electrode leading foot, anode, electrolyte, negative electrode adopt stacked system to arrange in one plane, adopt the winding method difference to come with existing anode, electrolyte, negative electrode.
Description of drawings
Below in conjunction with accompanying drawing to brief description of the present invention.
Accompanying drawing is circuit theory diagrams of the present invention.
1. shells among the figure, 2. anode, 3. electrolyte, 4. negative electrode, 5. anode leading foot, 6. negative electrode leading foot.
Embodiment
In the embodiment in figure 1, we the present invention is further described as example to implement a kind of plane electrolytic capacitor:
In Fig. 1, shell 1 usefulness insulating material is made, and also can use plastic casing, and plastics require thinner at upper and lower surface; Anode 2, electrolyte 3, negative electrode 4 adopt the material requirements of common electrochemical capacitor to make, difference is, anode 2, electrolyte 3, negative electrode 4 be according to the needs of electrochemical capacitor thickness, can lamination, but do not reel, make thickness reach requirement, such as requiring 2 millimeters thick, according to the thickness of material, can fold layer 2-3, what of lamination will be according to the capacity of electric capacity needs, allow area occupied, and required thickness decides; Anodal leading foot 5 adopts metal material to be connected with anode 2, negative electrode leading foot 6 adopts metal material to be connected with negative electrode 4, the present invention has just changed the arrangement of anode 2, electrolyte 3, negative electrode 4, other technologies require to make the same with common electrochemical capacitor, the manufacturing technology of electrochemical capacitor has been very ripe technology, is not described in detail at this.
Adopted the solution of the present invention, can be made into square shape or laminar to electrochemical capacitor, changed traditional columniform structure, be particularly suitable for requiring having broad application prospects in the very little electronic product of electrochemical capacitor thickness.
