Scalable Synthesis of Honeycomblike V₂O₅/Carbon Nanotube Networks as Enhanced Cathodes for Lithium-Ion Batteries

A green and scalable route to form a honeycomblike macroporous network by homogeneously weaving V 2 O 5 nanowires and carbon nanotubes (CNTs) was developed. The intertwinement between V 2 O 5 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 V 2 O 5 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.
