Abstract: A quality-improving method is proposed for producing an electrode, e.g. a negative electrode for lithium-ion batteries, comprising providing a carrier in the form of a foil, coating the carrier with a first coating material on at least one of the two sides of the carrier on the carrier surface, to give an adhesion layer, coating the carrier with a second coating material on the first coating material, so that the first and second coating materials each form a layered arrangement composed of a first layer of the first coating material and a second layer of the second coating material on the carrier, where the first and second coating materials used are different materials.

Abstract: The invention relates to a method for producing a substrate coated with a paste or dry coating, the method comprising: providing a film; providing a paste/dry coating; coating the film with the paste in order to obtain a coated substrate; and drying the paste or solidifying the dry coating on the substrate, the substrate being transported in a transport direction between its provision and the drying and/or solidification process, and the particles in the force field being oriented perpendicular to the transport direction. In order to improve the transport process, the substrate is shaped before and/or during the drying/solidification process in order to counteract tensioning of the substrate caused by shrinkage of the coating.

Abstract: A coating device for coating a carrier with a coating is proposed, comprising a transport device for transporting the carrier during the coating process for coating the carrier on at least one side of the carrier and for transportation at least after the application of the paste to one side, and an aligning device. For particularly stable sheet guidance, the transport device comprises a supporting device for the positionally stable supporting of the carrier with regard to the direction perpendicular to the transport surface, in which the carrier lies during transport, and/or perpendicular to the transport direction, which is configured to form a mechanical constraint for the range of movement of the carrier perpendicular to the surface in the direction of the uncoated side of the carrier, in order to counteract a change in the position with regard to the direction perpendicular to the surface.

Abstract: A method of dry coating of surfaces of a carrier and/or of production of self-standing layers, especially for use in lithium ion batteries having improved properties, is proposed, wherein the coating is effected at least by means of a particle-comprising powder in the dry state, especially having a solvent content of less than 1% by weight, and alignment of the particles is conducted in order to reduce the ionic resistance of the powder layer. The alignment of the particles additionally comprises fluidization of the powder.

Abstract: The invention relates to a method for orienting particles in a paste, comprising: providing the paste, which comprises particles that can be oriented in the paste, wherein the paste comprises, in particular, carbon-based particles, preferably graphite, and/or a volatile substance, and exposing the paste to the influence of a force field such that the particles experience a force due to the interaction with the force field, by means of which the particles are oriented relative to the field lines of the force field. For cost savings and improvement to productivity, the paste is heated in order to at least temporarily reduce the viscosity of the paste and to reduce the orientation time required for orienting the particles in the force field, wherein the paste is heated before exposing and/or while exposing the paste to the influence of the force field.

Abstract: Processes for applying magnetic fields to articles such as a layer or layer-coated articles, and more particularly to coatings having graphite particles, preferably for manufacture of negative electrodes having aligned graphite particles, for example for fast-charging lithium-ion batteries. The application of magnetic fields may be continuous. For this, magnetic tools with permanent magnets may be used for applying magnetic fields, wherein an article is moved relative to a magnetic tool. Application of magnetic field is made before the initiation of a drying phase and/or during a drying phase.

Abstract: Processes and apparatus for production of coatings applicable particularly for manufacture of electrodes, and more particularly for the manufacture of electrodes for use in lithium-ion batteries. Coatings may be produced from thermoresponsive pastes that contain solids particles and a thermoresponsive component, the coating or layer being coated on a carrier, solidified and dried; and wherein less than 80% of a volatile solvent component is removed from the coating during solidification.

Abstract: The invention relates to a method for applying magnetic fields to an article (020), which is in particular a layer or a layer-coated article, and more particularly to a coating having graphite particles, preferably for manufacture of a negative electrode with aligned graphite particles, for example for fast-charging lithium-ion batteries. In particular, the application of magnetic fields should be continuous. For this, a magnetic tool with permanent magnets (010) is used for applying magnetic fields, wherein the article is moved relative to the magnetic tool. The application of the magnetic field is carried out in particular before the initiation of a drying phase (030) and/or during the drying phase.
