▎ 摘 要
NOVELTY - An electrode material comprises a stacked vanadium pentoxide ribbons containing substrate, graphene oxide sheets infiltrating the substrate to an electrode material and water molecules present between adjacent vanadium oxide ribbons. Each respective graphene oxide sheet is positioned between two adjacent vanadium pentoxide ribbons. The amount of graphene oxide in electrode material is 2 wt.% or less. The amount of water molecules is present in vanadium pentoxide is 0.3 or more. USE - Electrode material is used in electrode composition used for preparing cathode material for electrochemical cell (all claimed) e.g. lithium ion battery used as power supply for portable electronics, hybrid electric vehicles and electric motors. ADVANTAGE - The electrode material provides electrochemical cell with excellent conductivity, structural stability, ion diffusion, availability and durability, and high specific capacity and high energy. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) electrode composition, which comprises vanadium pentoxide substrate, graphene sheet, composite substrate and water molecules. Each sheet is positioned between two adjacent vanadium pentoxide substrates. At least some water molecules are present between any two adjacent vanadium oxide substrates; and (2) preparation of vanadium oxide cathode material.
