Anisotropic crystallite size distributions in LiFePO(4) powders

The anisotropic crystallite sizes in high-performance LiFePO(4) powders 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 determi...

description The anisotropic crystallite sizes in high-performance LiFePO(4) powders 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 sizes L̄(V[001])/L̄(V[010]) = 1.41) the number of the composite particles was at least 30%.
