Abstract
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.
