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

Abstract

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.
