Cobalt(II) monoxide nanoparticles embedded in porous carbon nanofibers as a highly reversible conversion reaction anode for Li-ion batteries

Abstract

CoO nanoparticles embedded in porous carbon nanofibers (CNFs), which are used as a novel conversion reaction anode electrode, are successfully synthesized via one-step electrospinning and subsequent calcination in an Ar atmosphere. High capacity, excellent cyclability, and superior rate capability are achieved by a highly reversible conversion reaction of CoO nanoparticles and facile electron transport through highly conductive CNFs.
