摘要：

A thin polymer shell helps V2O5 a lot. Short V 2O5 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. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
