Template-free bottom-up synthesis of yolk-shell vanadium oxide as high performance cathode for lithium ion batteries

摘要

A template-free strategy is exploited to bottom-up synthesize yolk-shell vanadium oxide through a two-step spontaneous assembly of hydrolytically formed subunits in a one-pot process. The unique structured vanadium pentoxide exhibits excellent cathode performance for lithium ion batteries. Fabrication of yolk-shell vanadium oxides with controllable void space, internal architecture and morphology has recently attracted great interest because of their fascinating potential in drug delivery, catalysis, energy storage and conversion.
