The vanadium doping strategy has been found to encourage the spherical growth of lithium iron phosphate material, resulting in nano-spherical particles with a balanced transverse and longitudinal growth rate. This growth pattern is attributed to the interplay between the “Mosaic models” and “Radial models” of lithium ion diffusion.
