Olivine-type LiFePO4 crystals were prepared from a precursor phase Fe3(PO4)2(H2O)8 by a reaction with LiOH under a hydrothermal condition. Particular rod-like units assembled in the same crystallographic orientation were formed in association with l-(+)-ascorbic acid as a reducing and capping agent. Fagot-like mesocrystals were constructed with the oriented rods through parallel growth by supplying abundant Fe2+ and PO43' ions from the precursor phase. An increase in the concentration of the organic additive decreased the unit size, and sheaf-like mesocrystals of LiFePO4 nanorods with high crystallinity and porous structure were obtained.
