VO₂(B)/Graphene Composite-Based Symmetrical Supercapacitor Electrode via Screen Printing for Intelligent Packaging.

More multipurpose and convenient demand driven by Radio Frequency Identification (RFID) and intelligent packaging require flexible power sources. A VO₂(B)/graphene (VO₂(B)/GN) core-shell composite was successfully synthesized by the hydrothermal treatment with V₂O₅ and graphite. The as-obtained sample was characterized by XRD, FT-IR, SEM, TEM, and XPS measurements.
