Performance and morphology of centrifugally spun Co3O4/C composite fibers for anode materials in lithium-ion batteries

Centrifugally spun polyacrylonitrile (PAN) microfibers surface-coated with Co3O4 nanoparticles were prepared as precursors to produce coated Co3O4 carbon-fiber (CCF) composites for lithium-ion battery anodes. The Co3O4/C composite-fiber anodes were obtained after the stabilization of surface-coated Co3O4/PAN fibers at 200 °C for four hours, and subsequent carbonization at 600 °C for 6 hours. The electrochemical performance of the Co3O4/C...
