    Abstract

    The anisotropic crystallite sizes in high-performance LiFePO4powders were measured by XRD and compared with the particle sizes found by TEM image analysis. Lognormal particle size distribution functions were determined for all three main crystallographic axes. A procedure was developed to determine the fraction of the composite particles which consists of several crystallites and contains small- and large-angle boundaries. In a sample with the most anisotropic crystallites (ratio of volume-weighted mean crystallite sizesL̄V[001]/L̄V[010]= 1.41) the number of the composite particles was at least 30%.
