Abstract:
The present invention relates to a carbon nanofiber composite, and more specifically, to a technology for manufacturing a silicon carbon nanofiber composite in which nano-sized silicone is dispersed and applying the composite to a lithium secondary battery by adding one or more of either silicone or silicon oxide and a stabilizer for the silicone or silicon oxide to a spinning solution containing a carbon fiber precursor and performing electrospinning, oxidation stabilization, and carbonization.

Abstract:
PURPOSE: A metal oxide-carbon particle-carbon nanofiber composite is provided to cause polarity on the surface, to ensure high porosity, and to draw synergistic effect of a carbon fiber precursor such as metal alkoxide which effectively store ions and PAN(poly(acrylonitrile)) with excellent mechanical property. CONSTITUTION: A metal oxide-carbon particle-carbon nanofiber composite contains metal oxide and carbon particles which are uniformly dispersed. A method for preparing the composite comprises: a step of preparing a spinning solution containing metal alkoxide(M(OR)_n), the carbon particles, a carbon fiber precursor; a step of electrospinning the spinning solution to obtain a precursor spun fiber; a step of oxidizing and stabilizing the spun fiber to obtain flame retardant fiber; and a step of carbonizing the flame retardant fiber.
