WS2 nanotubes were synthesized by sintering amorphous WS3 at high temperature under flowing hydrogen. High-resolution transmission electron microscopy observation revealed that the as-prepared WS2 nanotubes have an open end with an inner hollow core of about 4.6 nm. We studied the lithium intercalation behavior of WS2 nanotubes. The WS2 nanotubes demonstrated a stable cyclability in a wide voltage range (0.1-3.1 V vs. Li/Li+). The nanotubes could provide a new class of electrode materials for lithium-ion batteries. (C) 2004 The Electrochemical Society.
