Abstract

Double-wall amorphous FePO₄ nanotubes are prepared by an oil-phase chemical route. The inward diffusion of vacancies and outward diffusion of ions through passivation layers result in double-wall nanotubes with thin walls. Such a process can be extended to prepare hollow polydedral nanocrystals and hollow ellipsoids. The double-wall FePO₄ nanotubes show interesting cathode performance in Li ion batteries.
