Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high-capacity capacitor electrode and a capacitor including the same and a stacked capacitor including the capacitor,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capacitor electrode, and relates to a high-capacity capacitor electrode and a capacitor including the same and a laminated capacitor.

Conventional supercapacitor electrodes have used activated carbon, which is a carbon-based material with porous structure and low electrode resistance.

The driving principle of the basic supercapacitor is the principle of this energy element that the ions in the electrolyte adsorb and desorb the charge through the electrode and store and discharge the charge.

However, it is difficult to substitute a lithium secondary battery because of the small electricity storage capacity of a carbonaceous supercapacitor in an application field which needs to be stored for a long time like a real life mobile phone.

In order to solve such a problem, studies on a pseudo capacitor using a metal oxide and a conductive polymer material have progressed, and the capacity of a conventional capacitor has dramatically improved. However, metal oxides with low conductivity have advantages in terms of energy capacity, but have a poor aspect in terms of instantaneous charge-discharge.

1 is a schematic view showing a capacitor electrode according to an embodiment of the present invention.

Referring to FIG. 1, a capacitor electrode 10 according to an embodiment of the present invention may include a current collector substrate 100 and a metal oxide nanostructure 210 coated with a conductive polymer layer.

The collector substrate 100 may include stainless steel (SUS), nickel foil, or indium tin oxide (ITO).

Particularly, in order to realize a flexible capacitor, a substrate having a complex form including graphene and carbon nanotubes as the current collector substrate 100 may be used.

The metal oxide nanostructure (200 in FIG. 4 (b)) is located on the upper and lower surfaces of the current collector substrate 100. That is, the metal oxide nanostructure (200 in FIG. 4 (b)) is positioned in both directions of the current collector substrate 100. For example, a first metal oxide nanostructure (201 of FIG. 4 (b)) is placed on the upper surface of the current collector substrate 100, and a second metal oxide nanostructure (202 in Fig. 4 (b)) can be located.

Therefore, compared with the case where the metal oxide nanostructure is unidirectionally grown on the current collector substrate 100, the case where the metal oxide nanostructure is grown in both directions of the current collector substrate 100 provides an electrode having a capacity twice that of the electrode can do.

The metal oxide nanostructure (200 in FIG. 4 (b)) at this time is a structure for increasing the capacity of a capacitor per unit area, and may be a two-dimensional nanostructure. For example, the metal oxide nanostructure (200 in FIG. 4 (b)) may be a nanowall structure.

The metal oxide nanostructure (200 in FIG. 4 (b)) is formed of cobalt oxide (Co 3 O 4 ), nickel oxide (NiO), iron oxide (Fe 3 O 4 ), ruthenium oxide (RuO 2 ), manganese oxide 2 ), tin oxide (SnO 2 ), vanadium oxide (V 2 O 5 ), or titanium oxide (TiO 2 ).

The conductive polymer layer may be coated on the surface of the metal oxide nanostructure. Therefore, the metal oxide nanostructure 210 coated with the conductive high-dielectric layer may be disposed on the upper and lower surfaces of the current collector substrate 100. For example, a first metal oxide nanostructure 211 coated with a conductive polymer layer is disposed on the upper surface of the current collector substrate 100, and a second metal oxide nanostructure 211 coated on the lower surface of the current collector substrate 100, The metal oxide nanostructure 212 may be located.

Therefore, by coating the conductive polymer layer on the surface of the metal oxide nanostructure, the conductivity of the metal oxide can be improved and the conductivity can be improved.

As the conductive polymer layer, various known conductive polymer materials may be used. For example, the conductive polymer layer may be formed of a material selected from the group consisting of polypyrrole, poly (3,4-ethylenedioxythiophene) -poly (3,4- ethylenedioxythiophene) -poly (styrenesulfonate), polyaniline ) Or polythiophene.

Meanwhile, a gel electrolyte (300 in FIG. 4 (d)) that surrounds the current collector substrate 100 on which the metal oxide nanostructure 210 coated with the conductive polymer layer is disposed may be further included.

When the gel electrolyte is used, it is possible to provide a flexible solid state energy element.

As such a gel electrolyte (300 in Fig. 4 (d)), for example, a basic electrolyte based on potassium hydroxide can be used.

2 is a schematic diagram illustrating a capacitor according to an embodiment of the present invention.

2, a capacitor 1 according to an exemplary embodiment of the present invention includes a first capacitor electrode 10A, a second capacitor electrode 10B spaced apart from the first capacitor electrode 10A, And a gel electrolyte 300 surrounding the first capacitor electrode 10A and the second capacitor electrode 10B.

The first capacitor electrode 10A and the second capacitor electrode 10B may be the capacitor electrode described above with reference to FIG. Therefore, detailed description thereof will be omitted.

At this time, the capacitor 1 according to the present invention may be formed by filling the gel electrolyte 300 between the first capacitor electrode 10A and the second capacitor electrode 10B.

For example, the capacitor electrode shown in FIG. 1 may be used as the first capacitor electrode 10A and the second capacitor electrode 10B. At this time, the first capacitor electrode 10A and the second capacitor electrode 10B are first wrapped with the gel electrolyte 300, and then the first capacitor electrode 10A and the second capacitor electrode 10B are formed by using the sticky characteristics of the gel electrolyte 300, The electrode 10B can be bonded. The gel electrolyte 300 may be formed by filling the gap between the first capacitor electrode 10A and the second capacitor electrode 10B while covering the first capacitor electrode 10A and the second capacitor electrode 10B. .

The first capacitor electrode 10A and the second capacitor electrode 10B are spaced apart from each other by the distance between the first capacitor electrode 10A and the second capacitor electrode 10B It means that the nanostructures coated with the metal oxide are spaced apart from each other. Therefore, when the gel electrolyte is included in the configuration of the first capacitor electrode 10A and the second capacitor electrode 10B at this time, these gel electrolytes may be in contact with each other.

3 is a schematic view showing a laminated capacitor according to an embodiment of the present invention.

Referring to FIG. 3, a multilayer capacitor according to an embodiment of the present invention includes a first capacitor electrode 10A, a second capacitor electrode 10B. And a gel electrolyte (300) surrounding the first capacitor electrode (10A) and the second capacitor electrode (10B). The unit capacitors (1A, 1B, 1C) 1C may be adhered and laminated by the gel electrolyte 300. For example, the laminated capacitor according to the present invention may have a structure in which the first unit capacitor 1A, the second unit capacitor 1B, and the third unit capacitor 1C are stacked in a multilayer form. At this time, there is no particular limitation on the number of unit capacitors of the laminated capacitor.

The unit capacitors 1A, 1B, and 1C may be the capacitors described above with reference to FIG.

Therefore, the unit capacitors 1A, 1B and 1C are located in such a manner that the gel electrolyte 300 surrounds the first capacitor electrode 10A and the second capacitor electrode 10B, so that the plurality of unit capacitors 1A, 1B, and 1C can be stacked in multiple layers by sticking to each other due to the sticky characteristics of the gel electrolyte 300.

The first capacitor electrodes 10A of the unit capacitors 1A, 1B and 1C are electrically connected to the first external electrode 410 and the second electrodes of the unit capacitors 1A, 1B, And the capacitor electrodes 10B may be electrically connected to the second external electrode 420. [

Therefore, at least a part of the current collector substrate of the first capacitor electrodes 10A and the first external electrode 410 are electrically connected, and at least a part of the current collector substrate of the second capacitor electrodes 10B is electrically connected to the second external And may be electrically connected to the electrode 420. Therefore, the first capacitor electrode 10A and the second capacitor electrode 10B surround the surface of the gel electrolyte 300. In order to electrically connect the external electrode 410 and 420, at least part of the current collector substrate The exposed portions of the current collector substrate and the external electrodes 410 and 420 may be connected to each other.

4 is a schematic view showing a method of manufacturing a capacitor according to an embodiment of the present invention.

Referring to FIG. 4A, a current collector substrate is first prepared.

Referring to FIG. 4 (b), a metal oxide nanostructure can be formed on the upper and lower surfaces of the current collector substrate by hydrothermal synthesis. For example, a nickel nanowire can be grown on the upper and lower surfaces of a substrate by hydrothermal synthesis on a graphene-carbon nanotube composite substrate.

Referring to FIG. 4 (c), a conductive polymer layer may be coated on the metal oxide nanostructure to form a capacitor electrode. For example, the conductive polymer layer may be coated on the metal oxide nanostructure through polymerization. For example, polypyrrole can be coated on the nickel oxide nanowire through polymerization.

Referring to FIG. 4 (d), two capacitor electrodes manufactured through FIGS. 4 (a) to 4 (c) may be spaced apart from each other and then a capacitor may be manufactured through a gel electrolyte coating. Meanwhile, the capacitor electrodes manufactured through the step of FIG. 4 (c) may be coated with a gel electrolyte and then adhered using the sticky characteristics of the gel electrolyte to manufacture a capacitor.

Furthermore, a laminated capacitor can be manufactured by stacking a plurality of the capacitors manufactured as described above using the sticky characteristics of the gel electrolyte. This is because the gel electrolyte is located not only between the capacitor electrodes but also around the entire capacitor, so that a plurality of capacitors can be stacked.

Comparative Example

(NiO NW one side growth) in which nickel oxide nanowires were grown only in one direction of the current collector substrate.

First, hydrothermal synthesis was performed on a stainless steel substrate (or a graphene / carbon nano-butt composite), which was a current collecting substrate, to form a two-dimensional nickel oxide nanowire on only one side of the substrate. At this time, the opposite side of the substrate was marked with thermal imide tape to prevent growth on both sides of the substrate.

Production Example 1

(NiO NW two side growth) in which a two-dimensional nickel oxide nano-wall was grown in both directions of the current collector substrate according to the present invention.

Two - dimensional nickel oxide nanowires were formed on both sides of the substrate by hydrothermal synthesis on stainless steel (or graphene / carbon nano - butt composites possible), which is a current collecting substrate.

Production Example 2

A plurality of capacitors manufactured according to Production Example 1 were laminated to produce a laminated capacitor. At this time, the number of layers was 2 and 3 triples.

When comparing the characteristics of the capacitor according to the comparative example and the capacitor according to the manufacturing example 1 with reference to Figs. 5 to 8, the capacitor according to Production example 1 in which the nickel oxide nano-wall (NiO NW) Is larger than that of the comparative example. That is, the areal density was proportional to the area of the capacitor. It was confirmed that when the cell was grown in both directions (Production Example 1), the capacity was twice as large as that in the case of unidirectionally growing (Comparative Example).

Experimental Example 2

9 is a graph showing a current characteristic according to the potential of the multilayer capacitor according to Production Example 2. FIG.

Referring to FIG. 9, it can be seen that the capacity size increases when the number of unit capacitors is two, and the capacity size increases when the number of unit capacitors is three.

 10 is a graph showing potential characteristics of the multilayer capacitor according to Production Example 2 according to time.

Referring to FIG. 10, it can be seen that as the number of unit capacitors of the stacked capacitor is increased, the number of potential changes with time decreases.

11 is a graph showing an areal capacitance characteristic according to the current density of the multilayer capacitor according to Production Example 2. In FIG.

Referring to FIG. 11, it can be seen that as the number of unit capacitors of the stacked capacitor increases, the area capacity per current density increases.

 FIG. 12 is a graph showing areal capacitance characteristics according to the cycle number of the laminated capacitor according to Production Example 2. FIG.

Referring to FIG. 12, it can be seen that, when the charge / discharge cycle of the stacked capacitor proceeds, the initial area capacity is maintained in a similar form even if the number of unit capacitors of the stacked capacitor increases.

According to the present invention, a metal oxide having a theoretical capacity larger than that of carbon is used as an electrode material, and conductivity is improved by coating the metal oxide with a conductive polymer. In addition, it is possible to provide an electrode having a capacity twice as large as that of the electrode in which the metal oxide is grown only in one direction of the substrate through the growth of the metal oxide in the bidirectional rather than the unidirectional growth on the substrate.

In addition, a metal oxide-based material having a large theoretical capacity was synthesized in both directions of a flexible carbon substrate to provide a structure suitable for stacking super capacitors.

In addition, the capacity per unit area can be dramatically increased by stacking several layers of conventional supercapacitors having a small energy capacity using a gel-electrolyte coating method.

Therefore, it can be applied to portable applications such as a mobile phone and a display, since a large usage time is possible even in a short charging time.
