[0003] Graphene, one of the carbon allotropes, is sp 2 It is formed into a two-dimensional planar crystal structure in the shape of a hexagonal honeycomb through bonding, and has been in the spotlight in various fields since its discovery in 2004 due to its strength, high specific surface area, excellent electrical conductivity, lightweight properties, and physical stability.

[0004] In particular, graphene is recognized as a promising material for use as an active or conductive material in lithium-ion batteries due to reasons such as its superior characteristics in storing and releasing lithium ions compared to graphite, which was previously used as a negative electrode material, and its excellent electrical conductivity.

[0005] As such, various technologies, such as Chemical Vapor Deposition (CVD) and electrochemical oxidation-reduction methods, have been introduced to manufacture carbon or carbon composites, such as graphene, for application in lithium-ion batteries. However, these methods have problems such as difficulties in mass production due to complex manufacturing processes or the need to input a large amount of time and high energy, and they fail to meet expectations in terms of battery performance, such as the high electron mobility and ion conductivity required for lithium-ion batteries, as well as charge-discharge efficiency capable of storing and releasing relatively large amounts of lithium.

[0021] In addition, the carbon or carbon composite is characterized by being formed by carbonizing a polymer through local heat treatment or photothermal treatment using a laser.

[0022] In addition, the hybrid carbon composed of carbon or carbon composites and additive particles in the pores between the polymers is characterized by a form in which carbon or carbon composites formed by carbonizing the polymer through localized heat treatment or photothermal treatment using a laser, which are extended in the horizontal direction, and additive particles that are also extended in the vertical direction are mixed.

[0023] In addition, it is characterized by having a structure in which the polymer and hybrid carbon are continuously and repeatedly formed on a vertical cross-section.

[0024] In addition, it is characterized by having an electrical conductivity of 100 kΩ or less in the vertical direction.

[0025] In addition, the polymer is characterized by being formed in a shape that surrounds the pores on a horizontal cross-section.

[0026] In addition, the polymer is formed in a honeycomb shape on a horizontal cross-section, and the pores between the polymers are formed in a hexagonal shape.

[0027] In addition, the upper and lower surface portions on the vertical cross-section are characterized by being composed of a hybrid carbon layer consisting of carbon or a carbon composite and an additive.

[0028] In addition, the polymer is characterized by being composed of one or more combinations selected from polyimide (PI), polyethersulfone (PES), polyvinylidene fluoride (PVDF), polyacrylonitrile (PAN), polyvinylpyrrolidine (PVP), block copolymer, carbon polymer, aromatic polymer, vinyl polymer, cyclic polymer, polyetherimide (PEI), polyphenylsulfone (PPSU), polyketimine (PKI), polyetheretherketone (PEEK), phenol, and alkylphenol.

Ultimately, this significantly improves battery characteristics, such as increasing specific capacity and charge / discharge efficiency (CE), and maintaining charge / discharge efficiency over a long period.

[0049]

[0050] A hybrid carbon composite film having a polymer support according to the present invention forms a support structure in which a plurality of polymers are spaced apart from each other in a vertical cross-section, and hybrid carbon composed of carbon or a carbon composite and an additive is filled vertically into the pores, which are the spaces between the polymers, thereby forming a film shape. The polymer may also include an additive.

[0051]

[0052] In other words, when observed in a vertical cross-section, polymer supports made of polymer are arranged at regular intervals, and the spaces between them are filled in the vertical direction by hybrid carbon composed of carbon or carbon composites and additives to form pores.

[0053]

[0054] Here, the additives are graphene, reduced graphene oxide (rGO), sulfur (S), silicon (Si), silicon oxide (SiOx, 0 <x≤2), 금(Au), 은(Ag), 전도성 카본, 그래파이트, 이황화몰리브덴(MoS2), 금속과 탄소가 결합된 MXENE, 갈륨(Ga), 주석(Sn), 인(P), 게르마늄(Ge), 안티모니(Sb), 아연(Zn), 니켈(Ni), 철(Fe) 중에 선택되는 하나 이상의 조합을 포함하여 배터리의 양극 활물질, 음극 활물질 또는 도전재에 함유될 수 있는 소재일 수 있다.

[0055]

[0056] And the carbon or carbon composite may include one or more combinations selected from graphene, polymer graphene composite, conductive carbon, polymer carbon composite, and amorphous carbon.

[0057]

[0058] These carbons or carbon composites are formed by carbonizing polymers through localized heat treatment or photothermal treatment using a laser.

[0059]

[0060] As such, the present invention solves the disadvantage of structures composed solely of carbon or carbon composites, such as graphene, which fail to maintain their original shape due to easy breakage, by providing a structure that stably and robustly supports carbon or carbon composites such as graphene through a polymer. Furthermore, since this stable structure enables the fabrication of graphene structures in a plate-like form, such as a film, it is suitable for mass production methods such as roll-to-roll. In particular, the presence of hybrid carbon composed of carbon or carbon composites such as graphene and additive particles allows for the accommodation of a larger amount of lithium and improves electron and ion conductivity, thereby significantly improving battery characteristics, including increased specific capacity and charge / discharge efficiency (CE), as well as the maintenance of charge / discharge efficiency over a long period.

[0061]

[0062] In addition, this structure can be attributed to the lightweighting of the electrode material because the hybrid carbon, composed of additives and carbon or carbon composites such as graphene present in the pores, functions as a conductor and current collector, thus eliminating the need for separate conductive agents or current collectors such as Cu, and also eliminating the need for separate additives such as binders.

[0063]

[0064] In the present invention, the hybrid carbon composed of carbon or carbon composites and additives formed in the pores between polymers is formed in a form in which carbon or carbon composites formed by carbonizing polymers through localized heat treatment or photothermal treatment using a laser, which are extended in the horizontal direction, and additive particles that are also extended in the vertical direction are mixed. This improves the capacity to accommodate lithium, thereby enabling an improvement in the specific capacity relative to volume. For example, the hybrid carbon may be in the form of laser-induced graphene (LIG) extended in the horizontal direction and graphene reduced by oxide (rGO) extended in the vertical direction.

[0065]

[0066] These details can be seen from FIG. 1, which is a hybrid carbon composite film having a polymer support in which polyethersulfone (PES) is used as the polymer and reduced graphene oxide (rGO) is mixed as an additive during the manufacture of the polymer sheet. When examining the formed hybrid carbon, it can be seen that in addition to laser-induced graphene (LIG) formed in the horizontal direction, reduced graphene oxide (rGO) developed in the vertical direction is also visible.

[0067]

[0068] In addition, in the present invention, the polymer and hybrid carbon have a structure in which they are continuously and repeatedly formed in a vertical cross-section, making it possible to continuously produce them in the form of a film.

[0069]

[0070] A hybrid carbon composite film having a polymer support according to the present invention, which is formed with the structure described above, can have an electrical conductivity of 100 kΩ or less in the vertical direction by improving conductivity in the vertical direction through pores made of hybrid carbon.

[0071]

[0072] To further explain the structure of the hybrid carbon composite film having a polymer support according to the present invention, the polymer can be formed in a shape that surrounds the pores in a horizontal cross-section.

[0073]

[0074] In this way, the hybrid carbon filled into the pores takes on a form surrounded by a polymer, thereby maintaining its original shape more stably and robustly. Additionally, it can be continuously unfolded in the horizontal direction in this form to be produced in the form of a film, making mass production possible.

[0075]

[0076] More specifically, in the horizontal cross-section, the polymer is formed in a honeycomb shape, and the pores between the polymers can be formed in a hexagonal shape in the horizontal cross-section.

[0077]

[0078] This allows the gap between adjacent pores to be minimized, thereby increasing the pore area relative to the total film area. Since an increase in the pore area can increase the amount of hybrid carbon, it leads to better results in charge / discharge efficiency, electron mobility, and ion conductivity.

[0079]

[0080] In fact, as shown in Fig. 2, compared to a pore with a circular cross-section, by forming the pore with a hexagonal cross-section and the polymer support in a honeycomb shape, it is possible to confirm an improved specific capacity compared to a pore with a circular cross-section.

[0081]

[0082] In addition, in the present invention, the upper and lower surface portions on the vertical cross-section are formed into a hybrid carbon layer composed of carbon or a carbon composite and an additive, thereby improving electron mobility and ion conductivity, and above all, enabling it to function as a free-standing anode.

[0083]

[0084] The polymer in the present invention comprises one or more combinations selected from polyimide (PI), polyethersulfone (PES), polyvinylidene fluoride (PVDF), polyacrylonitrile (PAN), polyvinylpyrrolidine (PVP), block copolymer, carbonized polymer, aromatic polymer, vinyl polymer, cyclic polymer, polyetherimide (PEI), polyphenylsulfone (PPSU), polyketimine (PKI), polyetheretherketone (PEEK), phenol, and alkylphenol, but is not necessarily limited thereto.

[0085]

[0086] Hereinafter, a preferred embodiment of the method for manufacturing a hybrid carbon composite film having a polymer support according to the present invention will be described in detail with reference to the attached drawings.

[0087]

[0088] A method for manufacturing a hybrid carbon composite film having a polymer support according to the present invention comprises, as illustrated in FIG. 3, a step (a) of preparing a film made of a polymer material; an upper scanning step (b) of forming a layer made of hybrid carbon on the upper surface by carbonizing the polymer through local heat treatment or photothermal treatment using a laser on the upper side of the prepared polymer film; a pore scanning step (c) of forming pores made of hybrid carbon in the polymer film by carbonizing the polymer through local heat treatment or photothermal treatment using a laser on the upper side of the polymer film; and a lower scanning step (d) of forming a layer made of hybrid carbon on the lower surface by carbonizing the polymer through local heat treatment or photothermal treatment using a laser on the lower side of the polymer film.

[0089]

[0090] Here, the upper and lower sides do not necessarily refer to the top and bottom, but may be the opposite, or one side or the other.

[0091]

[0092] And in the step of preparing a polymer film, it can be manufactured by mixing a polymer, such as polymer powder, with additive particles.

[0093]

[0094] Specifically, as shown in FIG. 4, a polymer sheet containing additives can be manufactured and used by mixing polymer powder and additive particles, preparing a sheet material such as aluminum (Al) foil, spreading and applying it, and then drying.

[0095]

[0096] As such, the manufacturing method according to the present invention enables the formation of graphene-like carbon or carbon composites with a precise and accurate pattern of a desired shape by carbonizing a polymer film containing additive particles into a specific shape through localized heat treatment or photothermal treatment using a laser. Furthermore, it resolves the issues of process complexity and high energy input previously pointed out in manufacturing methods for graphene, thereby allowing for easy and convenient mass production. In particular, the density of the hybrid carbon or carbon composite is increased due to the inherent additive, thereby increasing the lithium capacity and making it possible to manufacture lithium-ion batteries with excellent capacity.

[0097]

[0098] To further explain the generation of hybrid carbon containing carbon or carbon composites during a scanning process such as a laser, a hybrid carbon layer is formed on the upper surface layer of the film through an upper scanning step, the hybrid carbon layer is filled vertically through a pore scanning step, and finally, a hybrid carbon layer is formed on the lower surface layer of the film through a lower scanning step. In this process, a polymer remains around the pores, thereby forming a structure in which a polymer support supports the pores.

[0099]

[0100] Through this process, hybrid carbon is formed in the upper and lower surface layers and pores.

[0101]

[0102] As explained earlier, in order to secure enhanced electron mobility and ion conductivity in the vertical direction of the film, pore formation occurs throughout the entire vertical direction of the polymer film during the pore scanning step.

[0103]

[0104] In addition, in the present invention, as a method for high-speed and continuous production of a hybrid carbon composite film having a polymer support, thermal processing means such as a laser scanner are placed at the top and bottom to simultaneously perform an upper scanning step, a pore scanning step, and a lower scanning step, thereby improving mass production capability.

[0105]

[0106] Hereinafter, the characteristics of a hybrid carbon composite film having a polymer support according to the present invention will be explained based on experimental or measurement data.

[0107]

[0108] First, Figures 5(a), (b), and (c) are cross-sectional SEM images of a graphene film (PES-rGO) formed by mixing a polymer, polyethersulfone (PES), and reduced-oxidized graphene, respectively; a graphene film (PES LIG) formed by laser-induced graphene formed through polyethersulfone (PES); and a hybrid carbon film (PES-rGO-LIG) formed by laser scanning a sheet composed of a polymer, polyethersulfone (PES), and an additive particle, reduced-oxidized graphene (rGO), as in the present invention. When comparing these, the PES-rGO-LIG graphene film according to the present invention can simultaneously show graphene in the form of LIG, which is formed and unfolded in a horizontal direction, and graphene in the form of redox graphene (rGO), which is formed and unfolded in a vertical direction, unlike other graphenes. From this, it can be seen that the density of carbon or carbon composites such as graphene is increased, and a larger capacity of lithium can be accommodated in the same volume.

[0109]

[0110] These characteristics can also be confirmed in Figures 5 (d), (e), and (f), where (d) compares the specific capacity of each graphene film electrode, (e) shows the change in specific capacity according to the charge / discharge cycle of each graphene film electrode, and (f) shows the capacity retention rate of each graphene film electrode. It can be seen that the PES-rGO-LIG graphene film, which is an embodiment according to the present invention, exhibits excellent numerical values ​​compared to other graphene film electrodes in terms of specific capacity (mAh / g), change in specific capacity according to the number of cycles, and capacity retention rate. In particular, the PES-rGO-LIG graphene film electrode, which is an embodiment according to the invention, maintains a specific capacity of 650 mAh / g or more for 200 cycles, and it can be confirmed that the change (decrease) in capacity with increasing cycles is extremely small. Furthermore, it can be confirmed that a capacity retention rate of 85% or more is obtained, thereby minimizing capacity fade.

[0111]

[0112] The present invention relates to a hybrid carbon composite film having a polymer support and a method for manufacturing the same, and since the technology can be actually used in various industrial fields such as lithium-ion batteries, it has industrial applicability.
