Carbon nanotube-amorphous FePO4 core–shell nanowires as cathode material for Li ion batteries

Carbon nanotube (CNT)-amorphous FePO(4) core-shell nanowires are synthesized by aqueous solution-based mineralization through sequential adsorption of Fe(3+) and PO(4)(3-) ions onto the CNT surface. The hierarchical nanostructure with FePO(4) shell directly grown on the CNT core exhibits excellent electrochemical properties and performance as a cathode material for Li ion batteries.
