Method for preparing conductor material with large surface area and the structure thereof

Abstract

The present invention provides a method for preparing conductor material with large surface area, which comprises steps of: forming a block layer on the outer surface of a support precursor (for example, a conductive nanometer fiber) for producing a mixed precursor; rolling the mixed precursor to crack a portion of the outer surface of the block layer for producing a plurality of crack-gaps and exposing a portion of the outer surface of the support precursor from the plurality of crack-gaps; and adding a conductor material to the mixed precursor so that the conductor material contacts and is connected electrically to the support precursor via the plurality of crack-gaps for producing a conductor material with large surface area.
