  • Spherical, porous carbon structure and a production method therefor
    Patent number: 9368801
    Abstract: The present application relates to a spherical, porous structure which is formed using a mold taking the form of a spherical nanoparticle aggregate, and relates to a production method therefor. According to one aspect of the present application, the production method for the spherical, porous structure comprises: the use of a mold taking the form of a spherical nanoparticle-carbon precursor aggregate comprising a carbon precursor on the surfaces of a plurality of nanoparticles, formed by removing solvent from droplets comprising the carbon precursor and the plurality of nanoparticles.
    Type: Grant
