1. the preparation method of an electrolytic condenser, said method may further comprise the steps at least:

  • A) on porous bodies, apply dispersion A);

    Said porous bodies comprises the porous electrode body (2) of electrode material at least and covers the dielectric (3) of this electrode material surface;

    Said dispersion A) comprise the particle B of conducting polymer at least) and dispersant D);

    Said particle B) also comprises at least a polymerization anionB), remove at least in part and/or solidify dispersant D for forming the solid electrolyte (4) on the surface of covering dielectric wholly or in part),It is characterized in that dispersion A) in conductive polymer particles B) average grain diameter be 1-100nm, particle B) the ratio conductivity of gained film under dried state be greater than 10S/cm, dispersion A) content of middle metal cation is less than 5,000mg/kg.
