A Composite Film of V₂O₅ and Multiwall Carbon Nanotubes as Cathode Materials for Lithium-Ion Batteries

Abstract:

In this paper, V₂O₅-Multiwall Carbon Nanotubes (MWCNTs) composite film is prepared through sol-gel technique and dip-coating method. MWCNTs pretreated by mixed acid, H₂O₂ and cheap V₂O₅ powder are used as raw materials. The morphology, structure and components of the composite film are characterized by corresponding testing instruments. The final electrochemical measurements indicate that: the V₂O₅-MWCNTs composite film as cathode materials for lithium batteries exhibits better electrochemical performance than ordinary V₂O₅ film.
