  • Publication number: 20240332485
    Abstract: A method is proposed for manufacturing dry electrodes on a current collector with the aid of a roller system. The roller system includes at least three rollers and the current collector. A first roller and a second roller are rotated in opposite rotational directions. Powder is poured into a calender gap formed by the first rotating roller and the second rotating roller, the powder being carried on the second roller. A signal is triggered with the aid of a control unit for setting a laminating gap between the second roller and the third roller, the third roller and/or the first roller and the second roller moving toward each other in the direction of the current collector. At least the third roller is rotated in the opposite direction of the second roller. The current collector is moved through the laminating gap.

  • Publication number: 20240170637
    Abstract: A method for the production of an electrode for a battery cell, with a coating process in which a current collector foil is coated with electrode material by means of a discharge system. The discharge system has a pair of rollers with rotating calender rollers spaced from each other by a roller gap. A powdered output component of the electrode material in the dry state is filled into a roller gap feed section and compacted in the roller gap under pressure and shear to form an electrode material film, which is applied to the current collector foil. The discharge system ensures a temporally and spatially constant and/or adjustable powder dosing into the roller gap.

  • Publication number: 20240151034
    Abstract: A beam (P) for a construction element for a wood-framed structure is disclosed. The beam comprises two longitudinal members (P1) which extend longitudinally parallel with, and at a distance from, each other. Each of the longitudinal members comprises an external face (P2) and an internal face (P3). The respective internal faces of the longitudinal members face each other. The beam is closed by closing panels (P5, P5?) which bear against the transverse sides of the longitudinal members. The external face of at least one of the longitudinal members is provided with at least one longitudinal groove for receiving a sealing strip which is suitable for providing a seal between the beam and another element, for example a counter-bracing panel of the structure incorporating the beam. The beam allows a wood-framed structure, such as a house or a building, to be constructed while ensuring that the building is completely sealed as soon as it is constructed.
