摘要：

Carbon nanotube (CNT)-amorphous FePO4 core-shell nanowires are synthesized by aqueous solution-based mineralization through sequential adsorption of Fe3+ and PO43- ions onto the CNT surface. The hierarchical nanostructure with FePO4 shell directly grown on the CNT core exhibits excellent electrochemical properties and performance as a cathode material for Li ion batteries.
