Abstract
The present disclosure relates to ground expanded graphite agglomerate compositions, methods for making such agglomerates, their use as conductive additive, and conductive composites including such ground expanded graphite agglomerates. The disclosure also pertains to methods for making such composites and the use of such composites in preparing thermally conductive materials. The agglomerates may be characterized by a certain softness allowing the agglomerates to dissolve, e.g., through shear forces applied during compounding, thereby leading to an improved feedability and a highly homogenous distribution of the expanded graphite material in the composite matrix.
