        Scientific and Technological Outcomes<\/h2>\n\n\n\n

        High-nickel NCM cathode materials, such as those investigated within HiBRAIN, are of major importance for electric-mobility applications. The project generated important scientific results concerning the hierarchical structuring of high-nickel NCM cathodes and improved the understanding of how microstructural features, in particular cracks and conductive-additive distributions, affect effective transport properties and electrochemical performance.<\/p>\n\n\n\n

        A particular focus was placed on the relationship between electrode morphology and fast-charging capability. Hierarchical nanostructuring was shown to offer possibilities for improving rate capability, while modifications involving carbon nanotubes as conductive additives were of particular interest from an application perspective.<\/p>\n\n\n\n

        Another major topic concerned the influence of cracks in primary and secondary active-material particles. Physics-based and mathematically systematic studies enabled morphological effects on transport properties to be distinguished from purely electrochemical degradation mechanisms. This is important for understanding and quantifying degradation in realistic electrode structures.<\/p>\n\n\n\n

        Detailed Scientific Achievements<\/h2>\n\n\n\n

        Materials Design and Hierarchical Electrode Structures<\/h3>\n\n\n\n

        The project demonstrated that substantial microstructural and morphological modifications can be achieved starting from commercially available materials. In particular, hierarchical nanostructuring provides a route toward improving the rate capability of high-nickel NCM cathode materials, with particular relevance for fast-charging applications.<\/p>\n\n\n\n

        The production of single-crystal materials through two different processing routes was also investigated. These developments are relevant for future solid-state battery concepts and provide possibilities for extending the developed material-design strategies to additional classes of battery materials.<\/p>\n\n\n\n

        The material-design capabilities established and further developed within HiBRAIN can therefore be transferred to future projects addressing both current lithium-ion and post-lithium battery materials.<\/p>\n\n\n\n

        Process Development and Scale-Up<\/h3>\n\n\n\n

        Significant progress was achieved in the scale-up of high-nickel NCM materials, both with respect to material synthesis and electrode fabrication. Although several of the technological challenges were material-specific, the developed methodological approaches are transferable to related material and electrode systems.<\/p>\n\n\n\n

        The project also highlighted the importance of tailor-made experimental materials for the systematic validation of computational models. Controlled variations of electrode and particle morphology provide essential data for separating individual structural effects and validating structure\u2013property relationships.<\/p>\n\n\n\n

        Cracks and Effective Transport Properties<\/h3>\n\n\n\n

        A systematic and mathematically rigorous methodology was developed to investigate the effect of cracks in primary and secondary particles on effective conductivity.<\/p>\n\n\n\n

        Cracks were represented by ellipses in two dimensions and ellipsoids in three dimensions. This parameterized description made it possible to study a broad range of crack geometries using a limited number of clearly defined parameters and therefore to derive representative rather than geometry-specific conclusions.<\/p>\n\n\n\n

        Based on homogenization theory, extensive simulation data were generated for individual cracks as well as interacting crack pairs. These data can also be used for training data-driven and AI-based models.<\/p>\n\n\n\n

        A particularly important result was the statistical identification of the crack area projected onto the transport direction<\/strong> as an effective damage parameter over a broad range of geometrical configurations.<\/p>\n\n\n\n

        Building on the single-crack analysis, the degradation of effective transport properties in polycrystalline structures with arbitrary crack orientations was subsequently investigated.<\/p>\n\n\n\n

        Data-Driven and Stochastic Microstructure Modeling<\/h3>\n\n\n\n

        The combination of experimental imaging, stochastic geometry and numerical simulations enabled the development of data-driven three-dimensional models of battery electrode microstructures, including the nanoporous binder\u2013conductive-additive phase.<\/p>\n\n\n\n

        These models provide a framework for systematically studying structure\u2013property relationships beyond individual experimentally observed microstructures and allow statistically representative virtual structures to be generated and investigated.<\/p>\n\n\n\n

        The resulting methodology establishes a basis for future developments involving digital twins, synthetic microstructure generation, AI-assisted structure\u2013property prediction and inverse electrode design.<\/p>\n","protected":false},"excerpt":{"rendered":"
