ACS Appl Mater Interfaces. 2017 Dec 13;9(49):42438-42443. doi: 10.1021/acsami.7b15136. Epub 2017 Dec 5.

Abstract

A green and scalable route to form a honeycomblike macroporous network by homogeneously weaving V2O5 nanowires and carbon nanotubes (CNTs) was developed. The intertwinement between V2O5 nanowires and CNTs not only integrates nanopores into the macroporous system but also elevates the collection and transfer of charges through the conductive network. The unique combination of V2O5 nanowires and CNTs renders the composite monolith with synergic properties for substantially enhancing electrochemical kinetics of lithiation/delithiation when used as a lithium-ion battery (LIB) cathode. This work presents a useful approach for a large-scale production of cellular monoliths as high-performance LIB cathodes.
