▎ 摘　　要

NOVELTY - An electrode material comprises a conductive matrix comprising graphene sheets (114), vanadium pentoxide substrates (112) coupled to the conductive matrix, and a silicon dioxide network (116) formed between the vanadium pentoxide substrates. USE - Material used for electrode of battery (all claimed) e.g. lithium-ion battery. Uses include but are not limited to portable electronics, electric vehicles, hybrid electric vehicles, energy storage device. ADVANTAGE - The material has excellent chemical stability and structural stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) battery, which comprises an electrode with the electrode material; and (2) manufacture of the vanadium pentoxide-silicon dioxide/graphene electrode material, which involves preparing a solution containing a vanadium oxide and a silicon oxide, subjecting the solution to ion exchange, adding graphene oxide to the solution, aging the solution to produce a hydrogel, drying the hydrogel to produce a xerogel, and heating the xerogel to reduce the graphene oxide to graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the vanadium pentoxide-silicon dioxide/graphene material.
