Tungsten Disulfide Nanotubes for Lithium Storage

Abstract

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