The invention relates to a secondary particle for a cathode of a secondary lithium battery cell that comprises a plurality of primary particles, each having a layered crystalline structure in which transition metal oxide layers and lithium layers alternate. Each of the primary particles has a spatial extension in the direction of its crystallographic c-axis that is greater than in a direction perpendicular to this axis. The invention also relates to a method for producing such a particle.

Secondary particle for a cathode of a secondary lithium battery cell and method for producing such a particle

A method, apparatus, system for batter material screening is disclosed. First, microstructure generation parameters for a plurality of microstructures are received, where the microstructure generation parameters include microstructure characteristics. Microstructure statistics are generated using a first artificial intelligence ('AI') model, where the received microstructure generation parameters are inputs for the first AI model. Microstructure properties are predicted using a second AI model for the microstructures based on the generated microstructure statistics, the received microstructure generation parameters, and battery cell characteristics. It is determined whether at least one of the microstructures is within a predefined energy profile range based on the predicted microstructure properties.
