1. a preparation method for pyrolysis amorphous carbon material, is characterized in that, described method comprises:

  • By hard carbon presoma and soft carbon matrix precursor by 1;

    (0.1-10) mass ratio add solvent after carry out mechanical mixture, obtain slurry;

    Wherein, solvent comprises a kind of or several arbitrarily mixture in water, ethanol, isopropyl alcohol, acetone, dimethyl formamide;

    Described hard carbon presoma comprises a kind of or several arbitrarily mixture in glucose, sucrose, lignin, cellulose, starch, phenolic resins, polyacrylonitrile, epoxy resin;

    Described soft carbon matrix precursor comprises a kind of or several arbitrarily mixture in coal tar asphalt, petroleum asphalt, mesophase pitch;

    The slurry mixed is dried in an oven;

    Carry out in inert atmosphere under 200 DEG C of-600 DEG C of conditions being cross-linked, solidifying 0.5-5 hour;

    In inert atmosphere again under 1000 DEG C of-1600 DEG C of conditions, heat treatment 0.5-10 hour, makes described hard carbon presoma and soft carbon matrix precursor generation cracking reaction;

    After cooling, obtain described pyrolysis amorphous carbon material.
