A V2O5/Conductive-Polymer Core/Shell Nanobelt Array on Three-Dimensional Graphite Foam: A High-Rate, Ultrastable, and Freestanding Cathode for Lithium-Ion Batteries

A thin polymer shell helps V2O5 a lot. Short V2O5 nanobelts are grown directly on 3D graphite foam as a lithium‐ion battery (LIB) cathode material. A further coating of a poly(3,4‐ethylenedioxythiophene) (PEDOT) thin shell is the key to the high performance. An excellent high‐rate capability and ult...

Description
Summary:A thin polymer shell helps V2O5 a lot. Short V2O5 nanobelts are grown directly on 3D graphite foam as a lithium‐ion battery (LIB) cathode material. A further coating of a poly(3,4‐ethylenedioxythiophene) (PEDOT) thin shell is the key to the high performance. An excellent high‐rate capability and ultrastable cycling up to 1000 cycles are demonstrated.
