  • CARBON NANOFIBER CONTAINING METAL OXIDE OR INTERMETALLIC COMPOUND, PREPARATION METHOD THEREOF, AND LITHIUM SECONDARY BATTERY USING SAME
    Publication number: 20130126794
    Abstract: The present invention relates to a method for preparing a carbon nanofiber in which a nano-sized metal oxide or an intermetallic compound is dispersed, and more specifically, provides a preparation method comprising the step of electrospinning a metal precursor/carbon fiber precursor solution and heat treating the same. The carbon nanofiber containing a metal oxide or an intermetallic compound can be used as an anode material for a secondary battery. According to the present invention, a secondary battery using the carbon nanofiber containing a metal oxide or an intermetallic compound as an anode material has excellent capacity, and shows excellent cycle stability, in other words, maintains a capacity of 90% or more of the initial capacity even after 100 cycles, and the like.
