  • Publication number: 20230101808
    Abstract: The invention relates to a method for producing at least one electrode for a battery cell, the method comprising at least the following steps: a) providing a suspension for creating the at least one electrode, at least one target process parameter (1) being specifiable for providing the suspension; b) capturing at least one actual process parameter (2) while providing the suspension in step a); c) performing a prediction of at least one property (4) of the suspension by means of a machine-learned prediction algorithm (5), which estimates the at least one property (4) of the suspension depending on the at least one actual process parameter (2) and taking into account information on previously provided suspensions; d) defining at least one target process parameter (1) for providing the suspension in step a) depending on the prediction results from step c).

  • Publication number: 20230003670
    Abstract: A method for determining the placement accuracy of a plurality of electrode sheets, wherein the electrode sheets extend on mutually parallel planes and are stacked on top of one another and form a stack; wherein the placement accuracy describes positions of the edges of all of the electrode sheets relative to one another in the stack; wherein the method is carried out using a measuring device having a two-dimensionally resolving X-ray system with at least one beam source for X-ray radiation and a detector.

  • Publication number: 20220057341
    Abstract: A computer-implemented method for processing volumetric scanning data comprises obtaining volumetric scanning data of a structural element, the structural element comprising a plurality of instances of two or more types of components. The volumetric scanning data is represented by a plurality of voxels. The method comprises assigning the plurality of voxels to one of the two or more different types of components identifying, for each type of component, the voxels that are part of a surface of an instance of the component. The method comprises extracting the surfaces of the instances of the components using the voxels that are part of the surface of the respective type of component. The method comprises determining information on a structural integrity of the structural element based on the extracted surfaces.
