As demand for portable electronic devices increases, much attention has been focused on improving the performance of energy storage devices such as batteries used in portable electronic devices. FIG. 1 is a graph called Ragone chart, which shows the relationship between power density and energy density of various types of energy storage devices so that performance characteristics between energy storage devices can be compared do.
Energy density is a measure of how long an electronic device can operate, such as dialing or uploading data, and how long an electronic device can be in a standby state. In general, a fuel cell or lithium Secondary batteries such as ion batteries have high performance characteristics.
Power density represents the ability to provide fast current bursts in a short time in devices such as cameras, hard disk drives, high-resolution displays, and the like, and capacitors and ultracapacitors generally exhibit high performance characteristics.
An ultracapacitor is an energy storage device that provides a very high capacitance compared to a normal capacitor, and is also referred to as a super-capacitor or an ultra-high-capacity capacitor (hereinafter referred to as a "super-capacitor"). A super capacitor is a power source that collects a lot of energy and emits high energy for tens of seconds or a few minutes, and satisfies performance characteristics that conventional capacitors and rechargeable batteries can not accommodate. However, supercapacitors have advantages of high output and fast charging / discharging, but their energy density is lower than that of secondary batteries, which limits application.

Hereinafter, the present invention will be described in detail with reference to the drawings. In describing the specific embodiments below, various specific details have been set forth in order to explain the invention in greater detail and to assist in understanding it. However, it will be appreciated by those skilled in the art that the present invention may be understood by those skilled in the art without departing from such specific details. In some cases, it should be mentioned in advance that it is common knowledge in describing an invention that parts not significantly related to the invention are not described in order to avoid confusion in explaining the present invention.
According to an embodiment of the present invention, a method of manufacturing a supercapacitor having a structure in which a textile-based material is used as an electrode substrate at both ends of a capacitor and an electrolyte is filled between the two electrode substrates is disclosed. Textile-based supercapacitors are flexible and adaptable to energy storage devices with high energy capacity and power output for commercializing flexible or wearable devices.
In one embodiment, the stretchable textile is coated with carbon nanotubes (CNT) so that the textile has electrical conductivity. At this time, in one exemplary method, the CNT can be coated by dipping the textile in the solution in which the CNT is dispersed.
Thereafter, tensile strain is preferably applied to the textile to improve electrical conductivity. In one exemplary method, tensile strains can be applied to the textile while both ends of the textile are secured to a pair of straps and the straps are spaced apart, and the tensile textiles can have increased electrical conductivity by more than 30%.
In a further embodiment, a metal oxide such as manganese dioxide (MnO2) may be further deposited on the tensile strained textile to improve the energy density and further coat the conductive polymer material thereon to improve the reliability as a capacitor .
A method of fabricating a textile-based supercapacitor will now be described with reference to FIG. FIG. 2 is an exemplary flowchart illustrating a method of fabricating a textile-based supercapacitor according to a first embodiment of the present invention.
First, a textile is formed in step S110. The material of the textile is not particularly limited. In one embodiment, a textile material generally used in garments may be used. For example, one or more fiber materials may be used, such as polyamide fibers such as nylon, polyester fibers, acrylic fibers, etc. Alternatively, textile fibers of natural fiber materials may be used.
Such textiles can be made of two- or three-dimensional arrangements of stretchable fibers, and having a three-dimensional arrangement in view of electrical conductivity and energy capacity is desirable for improving the performance of the capacitor.
Next, carbon nanotubes (CNTs) are coated on the textile in step S120. CNT is one of the most conductive materials among organic materials, though it differs depending on the surface treatment method. In one embodiment, the textile can be CNT coated through a dip coating process in which the textile is immersed and dried in a CNT solution.
The CNT solution in which the textile is immersed can be made by mixing the CNTs with an appropriate solvent. For example, an aqueous solution of isopropyl alcohol may be used as the solvent. The textile is then dipped into the CNT solution so that the CNT is deposited on the textile. After a certain period of time after immersion, take out the textile from the CNT solution and dry it. By immersing and drying the textile in one or a plurality of times, CNTs can be stably deposited on the textile at a high density, thereby improving electrical conductivity.
Then, in step S130, the CNT-coated textile is subjected to tensile deformation. The reason for stretching the textile at this stage is to improve the electrical conductivity of the textile. CNT - coated textiles with no tensile deformation are not high in electrical conductivity due to loose spacing between the fibers constituting the textile. However, when the tensile deformation is applied, the length of the textile increases and the electrical continuity of the CNTs increases. However, when the textile is excessively stretched at this time, the stretchability of the textile is lowered or the textile is cut off. Therefore, considering the relation between the improvement of the electric conductivity according to the tension of the textile and the reduction or the decrease of the elasticity of the textile, .
In this regard, Figure 3 is a block diagram for schematically illustrating an apparatus for tensile deformation of textile.

Referring again to FIG. 2, if the textile is tensile deformed to have a predetermined electrical conductivity in step S130, the remaining process for forming a supercapacitor may be performed in step S140. For example, if two CNT-coated and tensile-deformed electrode substrates are provided through steps S110 to S130, the capacitor can be completed by filling the electrolyte between the substrates and connecting the terminals to the respective substrates.
4 and 5 show the front and rear views of the step of performing tensile deformation on the textile (S130). Figures 4a and 5a are photographs of the textile before applying the tensile strain and Figures 4b and 5b are photographs of the textile after applying the tensile strain.
4A and 5A before the tensile strain is applied, the spacing between the fibers constituting the textile between the textiles is relatively loose, but the tensile strain is applied, so that the textiles are aligned in the tensile direction as shown in FIGS. 4B and 5B, It can be seen that this is closely adhered and thus the electric conductivity is improved.
6 is a flowchart illustrating a method of fabricating a textile-based supercapacitor according to a second embodiment of the present invention.
In comparison with the manufacturing method according to the first embodiment of FIG. 2, the method of FIG. 6 further includes a step S240 of coating a metal oxide on the textile between the textile tensile deforming step S230 and the capacitor forming step S250 And the other steps are the same or similar.
That is, in this second embodiment, after applying a tensile strain to the textile in step S230, the metal oxide is further coated on the textile in step S240. In this way, the electrical conductivity of the textile is increased by the tensile deformation of the textile, and then the metal oxide is further deposited on the textile to increase the energy density.
The kind of the metal oxide to be coated at this time is not particularly limited, and for example, manganese dioxide (MnO2) may be used. Also, a specific method of coating the metal oxide on the textile is not particularly limited, and the metal oxide can be coated by, for example, electroplating.
Alternatively, in the second embodiment, tensile deformation (S230) of the textile may be performed after coating the metal oxide (S240). That is, the step S230 of tensile strain of the textile may be performed after any one of the CNT coating step S220 and the metal oxide coating step S240.
7 is a flowchart illustrating a method of fabricating a textile-based supercapacitor according to a third embodiment of the present invention.
Compared to the manufacturing method according to the second embodiment of FIG. 6, the method of FIG. 7 includes coating the conductive polymer on the textile between the step of coating metal oxide on the textile (S340) and the step of forming the capacitor (S360) (S350), and the other steps are the same or similar.
That is, in this third embodiment, the metal oxide may be coated on the textile in step S340 and then the conductive polymer may be further coated on the textile in step S350. As described above, after the metal oxide is coated on the textile, the conductivity polymer can be further coated to prevent a decrease in electrical conductivity. That is, since the metal oxide such as MnO2 has a low electrical conductivity, if only MnO2 is coated as in the second embodiment of FIG. 6, the electrical conductivity of the textile may be lowered. Therefore, by further coating the conductive material on the textile as in the third embodiment, it is possible to prevent the decrease of the electrical conductivity due to the metal oxide.
The kind of conductive polymer to be coated at this time is not particularly limited, but in one embodiment, polypyrrole (PPy) can be used as the conductive polymer.
Alternatively, step S330 of tensioning the textile in the third embodiment may be performed after coating the metal oxide (S340) or after coating the conductive polymer (S350). That is, the step of tensile deformation of the textile (S330) may be performed after any one of the CNT coating step (S320), the metal oxide coating step (S340), and the conductive polymer coating step (350).
Although not shown in the drawing, as another alternative embodiment, it is also possible to coat only the CNT and the conductive polymer on the textile and not to coat the metal oxide. The case of this alternative embodiment is similar to the flow diagram of Fig. 6, except that step S240 of Fig. 6 is replaced by the step of coating only the conductive polymer, not the metal oxide, on the textile. It will also be understood that in this case, the step of tensile deformation of the textile may be performed after coating the conductive polymer on the textile.
8 is a graph for explaining electric conductivity measurement results according to tensile strain of the textile substrate. FIG. 8 is a measurement result when the CNT-coated textile is tensioned. In the graph, a black solid line indicates stress due to the tension of the textile, and a red solid line indicates the resistance change of the textile according to the textile tension.
Through the black solid line, if the tensile force applied to the textile is gradually increased, the stress applied to the textile gradually increases, and it can be seen that the textile is broken at a certain tensile strength. And, from the solid red line, it can be seen that even though the tensile force applied to the textile slightly increases only initially, the resistance of the textile decreases considerably and thereafter the resistance does not fluctuate significantly.
Therefore, the tensile deformation of the textile can be performed within a predetermined range in consideration of the change of the resistance characteristic according to the tensile force change to the textile. That is, until the resistance of the textile is minimized to the extent that the textile is not broken, the textile can be subjected to tensile deformation.
9 is a diagram for explaining an increase in energy density and power density of a tensile-deformed textile substrate. In the graph of Fig. 9, the horizontal axis represents the power density and the vertical axis represents the energy density. Two types of textiles (CNT, MnO2, MCCT, and CNT) were used for the experiment.
Inside the graph, hollow squares and triangles indicate MCCTs and CCTs without tensile deformation, respectively, and rectangles and triangles filled with trenches represent MCCTs and CCTs with tensile strain according to the present invention, respectively.
As can be seen from the graph, it can be seen that, when tensile strain is applied to all types of textiles, electric conductivity is improved and power density is increased and energy density is also increased. That is, in comparison with FIG. 1, it can be seen that the performance characteristic in the direction of the area A is improved with respect to the supercapacitor by simply subjecting the textile to CNT coating and then tensile strain as in the present invention.

This is possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the claims.
