摘要：
Thin self-standing films and powders of highly amorphous V2O5 have been prepared via a combined sol-gel and solvent exchange procedure. The amorphous V2O5 is a highly interconnected porous material with very thin solid walls and shows a unique lithium intercalation behavior. Electrochemical tests performed on composite cathodes made by mixing the material with carbon particles demonstrated a very high lithium insertion capacity.
