Description

AREA OF INVENTION

[0001] The invention relates to a positive electrode plate, in particular a manufacturing structure of a positive electrode plate in which positive electrode mass material is connected to the electrode plate by means of electrostatic adhesion. BACKGROUND OF THE INVENTION

[0002] In the current state of the art, a positive electrode comprises a substrate and a positive electrode suspension applied to it. The positive electrode suspension consists of a multitude of positive electrode particles suitable for storing and releasing lithium ions, several polymers, in particular PVDF (polyvinylidene fluoride), a solvent for dispersing the suspension, several conductive additives to increase electrical conductivity, and several ceramic particles for guiding the lithium ions into corresponding ion channels.

[0003] The solvent is added during the preparation of the positive electrode suspension to ensure a uniform distribution of the individual components. The solvent-containing positive electrode suspension is then applied to the substrate, and the solvent is removed by a curing or drying process. This conventional method is relatively simple, but it has several disadvantages. Firstly, uneven evaporation of the solvent during the curing process can impair the homogeneity of the initially well-mixed positive electrode suspension. Secondly, numerous pores often remain in the resulting positive electrode layer after the solvent evaporates. Therefore, an additional rolling or calendering step is usually required to improve the adhesion between the positive electrode layer and the substrate.This step not only increases manufacturing costs but also subjects the powdered material to considerable mechanical stress, which can lead to fractures or cracks and thus negatively affect the final electrochemical properties of the electrode. Furthermore, the solvent-based positive electrode suspension must be applied to the substrate immediately after its production. Consequently, the production of the positive electrode suspension and the positive electrode substrate must be closely coordinated. In addition, the moist positive electrode suspension has only limited storage stability, restricting the spatial and organizational flexibility of the production facilities. Finally, the necessary recovery of the evaporated solvent results in additional costs.

[0004] Against this background, the present invention aims to provide a manufacturing structure for a positive electrode plate in which positive electrode mass material is connected to the positive electrode substrate by electrostatic adhesion, and to specify a corresponding manufacturing process by which the disadvantages of the prior art described above are overcome. SUMMARY OF THE INVENTION

[0005] To improve upon the aforementioned shortcomings of the prior art, the present invention provides a manufacturing structure for a positive electrode plate coated with a positive electrode suspension by means of electrostatic adhesion. The positive electrode plate comprises a positive electrode substrate and a layer of positive electrode suspension adhering to it. The positive electrode suspension consists of a suitable material and is solid at room temperature. It is produced independently of the substrate and does not need to be mixed with it during the manufacturing process. The substrate and suspension can therefore be manufactured separately. The solvent-free, solid suspension is characterized by a longer shelf life. The manufacturing structure includes a raw material container for receiving the positive electrode suspension. The positive electrode mass material comprises: a plurality of positive electrode particles,which can store or release lithium ions; the positive electrode particles constitute an active material; a variety of PEOs (polyethylene oxides) which serve to guide lithium ions and increase the positive electrode's ability to guide lithium ions; the PEOs are thermoplastic, so they melt at high temperatures and are mostly in a molten state; a variety of PVDFs (polyvinylidene fluoride) or PVDF-HFPs (vinylidene fluoride-co-hexafluoropropylene); the PVDFs or PVDF-HFPs and the PEOs constitute a polymer material; when the positive electrode mass material is heated to a certain temperature, a copolymer of the PEOs and the PVDFs or PVDF-HFPs melts in the positive electrode mass material, causing the positive electrode mass material to become sticky; the sticky positive electrode mass material adheres to the positive electrode substrate.to form the positive electrode plate; a variety of conductivity agents serve to increase the electrical conductivity of the positive electrode suspension; a variety of lithium salts serve to facilitate the movement of the polymer chains of the polymer material and to increase the ionic conductivity; a variety of ceramic particles serve to guide the lithium ions to form lithium ion channels in order to prevent side reactions between the lithium ions and the positive electrode suspension due to abnormal deposition of lithium ions in the positive electrode suspension; the variety of positive electrode particles, ceramic particles, conductivity agents, and lithium salts are dispersed in the polymer material.which supports the positive electrode suspension; the material of the positive electrode suspension is a solid at room temperature; when the material of the positive electrode suspension is heated to a specific temperature between 50°C and 240°C, the PEOs in the material of the positive electrode suspension melt, so that the material of the positive electrode suspension adheres to the substrate of the positive electrode and forms the positive electrode plate; an electrostatic spray gun is connected to the raw material container and serves to hold the positive electrode suspension. It applies a voltage to the suspension, which generates electrostatic charges on its surface and forms charged fine particles. These fine particles are sprayed from the outlet of the spray gun. A roller belt mechanism is located at the outlet.which transports a carrier plate. This carrier plate receives the sprayed fine particles and sprays them onto the substrate of the positive electrode to form a first electrode plate. Since each particle of the positive electrode material is extremely small, the particles electrostatically adsorb to each other when sprayed onto the carrier plate using the electrostatic spray gun, thus forming a high layer density. This creates a positive electrode plate with high energy density and increased lithium-ion conductivity. Upon contact of the charged fine particles with the metal sheet, an electrostatic attraction occurs, causing the particles to adhere and form the first electrode plate. A heating element, connected to the roller belt mechanism, heats this first electrode plate, causing the charged fine particles to melt and adhere to the substrate of the positive electrode.to form the entire positive electrode plate. Since the positive electrode plate formed from the positive electrode mass material does not require any firing or rolling processes, the components of the positive electrode mass material are not damaged by thermal or mechanical stresses.

[0006] The invention presents according to Fig. A manufacturing structure for a positive electrode plate, coated with a positive electrode suspension by means of electrostatic adhesion, and the associated manufacturing process are provided. A positive electrode plate 20 consists of a positive electrode substrate 21 and a layer 22 of positive electrode suspension adhering to it. In conventional solid-state or semi-solid batteries, a solvent-containing positive electrode suspension is applied to the positive electrode substrate 21 and then formed into the positive electrode plate 20 by drying and rolling. However, both the positive electrode suspension and the positive electrode substrate 21 must be produced simultaneously.Furthermore, the moist positive electrode suspension has a limited shelf life, and subsequent drying and rolling processes can damage the materials in the positive electrode suspension, thus impairing battery performance. In the present invention, the positive electrode suspension consists of material 100. This material is solid at room temperature. The positive electrode suspension can be produced independently without having to be combined with the positive electrode substrate 21 simultaneously. Thus, the positive electrode substrate 21 and the positive electrode suspension 100 can be manufactured separately. The positive electrode suspension 100 itself is readily available. This allows for greater flexibility in the production of the positive electrode plate 20. Since the positive electrode suspension 100 is solvent-free and solid, it has a longer shelf life and can also be stored at room temperature.Since the positive electrode plate 20 with the positive electrode mass layer 22 formed from the positive electrode mass material 100 does not require baking and rolling steps, the materials inside the positive electrode mass material 100 are not damaged by thermal or mechanical stresses.

[0007] A manufacturing structure of the positive electrode plate 20, which is connected to positive electrode mass material 100 by electrostatic adhesion, comprises the following elements: A raw material tank 10 serves to hold the positive electrode suspension 100. The positive electrode suspension 100 is a powder with a particle diameter between 0.01 nm and 10 mm.

[0008] The positive electrode suspension 100 comprises the following elements: Several positive electrode particles 12 can store or release lithium ions, each of these particles 12 representing an active material. The positive electrode particles 12 are selected from a group consisting of LCO particles (LiCoO2), single-crystal NCM particles (lithium nickel manganese cobalt oxide), polycrystalline NCM particles, LMFP particles (lithium manganese iron phosphate), LFP particles (LiFePO4), and combinations thereof. Several polyethylene oxide (PEO) 14 particles serve to guide lithium ions and increase their conductivity at the positive electrode. Since the PEO 14 particles are thermoplastic, they melt at high temperatures and exist in a molten state. A variety of PVDFs (polyvinylidene fluoride) or PVDF-HFPs (vinylidene fluoride-co-hexafluoropropylene) 16. The PVDs or PVDF-HFPs 16 and the PEOs 14 form a polymer material 26. When the positive electrode suspension 100 is heated to a specific temperature, a copolymer of the PEOs 14 and the PVDs or PVDF-HFPs 16 melts in the positive electrode suspension 100, causing the positive electrode suspension 100 to become sticky. The sticky positive electrode mass material 100 can thus adhere to the positive electrode substrate 21 and form the positive electrode plate 20. Several conductivity agents 18, selected from at least one of the following materials: carbon nanotubes, graphene, and amorphous carbons, wherein the amorphous carbons are, for example, Super P. The conductivity agents 18 serve to increase the electrical conductivity of the positive electrode mass material 100.Several lithium salts 15 facilitate the sliding of the polymer chains of the polymer material 26 and increase the ionic conductivity, thereby further improving the electrochemical performance of the battery. The lithium salts 15 are selected from at least one of the following substances: PDDA-TFSI (poly(diallyldimethylammonium)-bis(trifluoromethanesulfonyl)imide) and Py14-TFSI. Several ceramic particles 160 guide the lithium ions and form dispersed lithium ion channels to prevent side reactions between the lithium ions and the positive electrode mass material 100 due to unnatural lithium ion deposition in the positive electrode mass material 100. The ceramic particles 160 are selected from a group consisting of LAGPs (lithium aluminum germanium phosphate), LATPs (lithium aluminum titanium phosphate), and LLZOs (Li-LasZr2O). 12, lithium lanthanum zirconium oxide), LLTOs (lithium lanthanum titanium oxide), LPSC (LPSCl, sulfide solid electrolyte) and combinations thereof. The positive electrode particles 12, the ceramic particles 160, the conductivity agents 18 and the lithium salts 15 are dispersed in the polymer material 26, which supports the positive electrode mass material 100.

[0009] The weight ratio of the "positive electrode particles 12", the "polymer material 26 and the lithium salts 15", and the "conducting agent 18 and the ceramic particles 160" is between 88 and 97:10 to 2:2 to 1. This means that the ratio of the "positive electrode particles 12" to the "polymer material 26 and the lithium salts 15" to the "conducting agent 18 and the ceramic particles 160" is A:B:C, where A is in the range of 88 to 97, B is in the range of 10 to 2, and C is in the range of 2 to 1. Values ​​of A, B, and C within the aforementioned ranges are permissible within the scope of the present invention. In this description, the terms defined above have the same meaning.

[0010] The positive electrode mass material 100 is solid at room temperature. When the positive electrode suspension 100 is heated to a specific temperature between 50°C and 240°C, the PEOs 14 contained therein melt. This allows the positive electrode mass material 100 to adhere to the positive electrode substrate 21 and form the positive electrode plate 20.

[0011] An electrostatic spray gun 30 serves to pick up the positive electrode material 100 in the raw material container 10 and to apply a voltage to the positive electrode material 100. The electrostatic spray gun 30 comprises: An electrostatic spray gun 30 is connected to the raw material container 10 and serves to pick up the positive electrode material 100 from the raw material container 10 and apply a voltage to it. The applied voltage generates electrostatic charges on the surface of the positive electrode material 100, resulting in charged fine particles 150. These charged fine particles 150 are sprayed through the outlet opening 34 of the electrostatic spray gun 30.

[0012] The electrostatic spray gun 30 has a voltage mechanism 32 for applying a voltage to the positive electrode material 100. The voltage is between 0.1kV and 100kV.

[0013] A roller conveyor mechanism 60 is located at the outlet 34 of the electrostatic spray gun 30. This mechanism conveys a carrier plate 65, which receives the charged fine particles 150 sprayed from the outlet 34. The charged fine particles 150 are sprayed from the outlet 34 onto the positive electrode substrate 21, thus forming a first electrode plate 500.

[0014] The individual particles of the positive electrode material 100 are extremely small. The particle size ranges from 0.01 nm to 10 mm. When the positive electrode material 100 is sprayed onto the carrier plate 65 using the electrostatic spray gun 30, the particles electrostatically adsorb to one another, forming a high layer density. This creates the positive electrode plate 20 with high energy density, which further increases the lithium-ion conductivity.

[0015] The roller belt mechanism 60 comprises a roller assembly 62 consisting of several rollers. A conveyor belt 64 is wound around the roller assembly 62, and the rollers in the roller assembly 62 drive the conveyor belt 64.

[0016] The carrier plate 65 is a metal sheet, preferably an aluminum sheet. The metal sheet is unwound from a metal roller 70. The metal roller 70 is connected to the roller conveyor mechanism 60. During operation, the metal sheet unwound from the metal roller 70 is laid flat on the conveyor belt 64 and moves with it. The metal sheet serves as a positive electrode pad 21. The rotation of the rollers in the roller assembly 62 moves the conveyor belt 64 and transports the positive electrode pad 21 located on it to the outlet 34 of the electrostatic spray gun 30.

[0017] When the charged fine particles 150 come into contact with the metal sheet, an electrostatic attraction arises between the charged fine particles 150 and the metal sheet. As a result, the charged fine particles 150 adhere to the metal sheet and form the first electrode plate 500.

[0018] A heating element 40 is connected to the roller belt mechanism 60 and heats the first electrode plate 500, so that the charged fine particles 150 become a molten material 200 and adhere to the positive electrode substrate 21, thus creating the positive electrode plate 20.

[0019] The positive electrode suspension 100 is solid at room temperature. When the positive electrode suspension 100 is heated to between 50°C and 240°C, the PEOs 14 contained therein melt and form a melt. As a result, the PEOs 14 adhere to the positive electrode substrate 21 and form the positive electrode plate 20.

[0020] The heating device 40 comprises two parallel pressure rollers 42. Between the pressure rollers 42 is a receiving chamber 46 for receiving the first electrode plate 500. Two heating elements 44 are arranged in each of the pressure rollers 42. These heating elements 44 heat the pressure rollers 42 and thus the charged fine particles 150 located in the receiving chamber 46. This causes the charged fine particles 150 to fuse with the molten material 200 and adhere to the metal plate, thereby forming the positive electrode plate 20.

[0021] The following describes a manufacturing process for the positive electrode plate 20, in which the positive electrode suspension 100 is applied by electrostatic adhesion using the electrostatic spray gun mechanism described above. The terms defined above have the same meaning in this description and are therefore not repeated in detail. As in Fig. As shown, the procedure comprises the following steps: Step A: The positive electrode mass material 100 in the raw material container 10 is introduced into the electrostatic spray gun 30 and the electrostatic spray gun 30 applies the voltage to the positive electrode mass material 100, so that the surfaces of the particles of the positive electrode mass material 100 are electrostatically charged to form charged fine particles 150. Step B: The charged fine particles 150 are applied from the outlet opening 34 of the electrostatic spray gun 30 onto the carrier plate 65 of the roller belt mechanism 60, thus forming the first electrode plate 500

[0022] Since the positive electrode suspension 100 has an extremely small particle size, it electrostatically adsorbs itself onto the carrier plate 65 when sprayed by the electrostatic spray gun 30, thus forming a high layer density. This creates the positive electrode plate 20 with high energy density and improves the lithium-ion conductivity.

[0023] Step C: The first electrode plate 500 is transported to the heating element 40 by means of the roller belt mechanism 60. Step D: The first electrode plate 500 is inserted into the heating element 40 and heated so that the charged fine particles 150 form the molten material 200 and adhere to the positive electrode substrate 21.

[0024] Step E: Through natural cooling, the molten material 200 solidifies and adheres to the positive electrode substrate 21, thus forming the positive electrode plate 20. At room temperature, the positive electrode mass material 100 forms the solid positive electrode mass layer 22.

[0025] By applying the above-mentioned manufacturing process, the positive electrode plate 20 is obtained, to which the positive electrode mass layer 22, formed from the positive electrode mass material 100, adheres. The positive electrode plate 20 comprises the positive electrode mass layer 22 and the positive electrode substrate 21, which is adhered to the positive electrode mass layer 22. The positive electrode mass layer 22 consists of the positive electrode mass material 100. This material 100 contains several positive electrode particles 12, PEOs 14, PVDFs or PVDF-HFPs 16, several conductivity agents 18, lithium salts 15, and several ceramic particles 160. The positive electrode particles 12, the ceramic particles 160, the conductivity agents 18, and the lithium salts 15 are dispersed in the polymer material that supports the positive electrode mass material 100.

[0026] As in Fig.As shown, a composite layer 110 surrounds the outer surface of each ceramic particle 160. The composite layer 110 consists of a dopamine layer 120, which surrounds the outer surface of the ceramic particle 160, and a PVDF layer 130, which surrounds the outer surface of the dopamine layer 120. The PVDF layer 130 consists of several PVDF components. The PVDF material of the PVDF layer 130 is formed during the fabrication of the composite layer 110 and not by a reaction with the PVDFs or PVDF-HFPs in the positive electrode mass 100. The dopamine layer 120 does not completely surround the outer surface of the ceramic particle 160, so that parts of the outer surface are exposed. As a result, some parts of the PVDF layer 130 come into contact with the outer surface of the ceramic particle 100, while other parts of the PVDF layer 130 come into contact with the dopamine layer 120.

[0027] The dopamine layer 120 consists of several copolymerized dopamine molecules. Dopamine is hydrophobic and prevents side reactions between the ceramic particle 160 and the solvent. Parts of the fluoride ions (F - In the PVDF of PVDF layer 130, hydrogen bonds form with nitrogen ions of the copolymerized dopamine molecules of dopamine layer 120. This causes the PVDF material to form PVDF layer 130 and to enclose the surface of dopamine layer 120.

[0028] The advantage of the present invention lies in the extremely small particle size of the positive electrode material. When the positive electrode material is sprayed onto the substrate using an electrostatic spray gun, the material electrostatically adsorbs itself, forming a high layer density. This results in a positive electrode plate with high energy density and increased lithium-ion conductivity. According to the invention, the production of the positive electrode material and the positive electrode substrate are completely separate. Therefore, the need to produce both simultaneously is eliminated when manufacturing the positive electrode plate. The positive electrode material is easy to obtain and can be stored at room temperature, which allows for greater flexibility in the production of the positive electrode plate. Conventional positive electrode materials contain solvents.Therefore, after the application of conventional positive electrode material to the positive electrode substrate, subsequent drying and rolling processes are required to ensure adhesion of the suspension layer to the substrate. This typically leads to higher costs. However, in the present invention, the positive electrode material adheres to the positive electrode substrate due to PEO's property of melting at high temperatures. Therefore, no solvent is required to bond the suspension material to the substrate. Drying and rolling processes are thus eliminated, thereby reducing manufacturing costs. Furthermore, the positive electrode material layer applied using this method exhibits a uniform thickness and high layer density, forming an electrode plate with high energy density.

[0029] The invention thus relates to a manufacturing structure for a positive electrode plate, which is provided with a positive electrode mass layer by means of electrostatic adhesion, wherein the positive electrode plate comprises a positive electrode substrate and a layer of positive electrode mass adhering thereto; the positive electrode mass consists of a positive electrode mass material; the positive electrode suspension is produced independently of the rest of the plate, without having to be combined with the positive electrode substrate in the manufacturing process; an electrostatic spray gun applies a voltage to the positive electrode mass material to generate charged fine particles; when the charged fine particles come into contact with a metal sheet, electrostatic attraction occurs, so that the charged fine particles adhere to the metal sheet and form the first electrode plate;A heater heats the first electrode plate, causing the charged fine particles to adhere to the positive electrode substrate and form the positive electrode plate.

[0030] In describing the present invention, it is obvious that it can be modified in many ways. Such modifications are not to be understood as deviations from the scope of protection of the invention, and all modifications that appear obvious to a person skilled in the art are to be included within the scope of protection of the following claims.

[12] Manufacturing structure for a positive electrode plate which is coated with positive electrode mass material by electrostatic adhesion, wherein the structure corresponds to any one of claims 1 to 10 and the method comprises the following steps: Step A: The positive electrode material from the raw material container is introduced into the electrostatic spray gun, and the electrostatic spray gun applies a voltage to the positive electrode material, so that the surfaces of the particles of the positive electrode material become electrostatically charged and charged fine particles are formed; and Step B: The charged fine particles are applied from the outlet of the electrostatic spray gun to the carrier plate of the roller belt mechanism to form the first electrode plate. Since the positive electrode material has an extremely small particle size, it electrostatically adsorbs itself onto the carrier plate when sprayed with an electrostatic spray gun, thus forming a high layer density. This creates the positive electrode plate with a high energy density, which improves the lithium-ion conductivity. Step C: The first electrode plate is transported to the heating element by means of a roller belt mechanism. Step D: The first electrode plate is heated in the heating element so that the charged fine particles melt and adhere to the substrate of the positive electrode. Step E: Through natural cooling, the molten material solidifies and adheres to the substrate of the positive electrode. This creates the positive electrode plate. At room temperature, the positive electrode material forms a solid layer.
