1. A ultracapacitor, comprised of:

  • (a) at least one printing substrate for receiving a deposition of dielectric material to form at least one printed structure for an ultracapacitor;

    (b) a high-temperature dielectric ink composition, comprised of a custom organic vehicle comprised of a polar solvent and a binderi. wherein said polar solvent comprises approximately 50% to approximately 80% of said custom organic vehicle,ii. wherein said binder comprises approximately 20% to approximately 50% of said custom organic vehicle,iii. wherein said custom organic vehicle comprises approximately 10% to approximately 20% of said dielectric ink composition;

    (c) a dielectric powder having an average particle diameter ranging from approximately 10 nm to approximately 750 nm, wherein said dielectric powder comprises approximately 30% to approximately 70% of said dielectric ink composition;

    (d) a dielectric constant glass, wherein said dielectric constant glass does not affect the Curie temperature of the dielectric powder during sintering and comprises approximately 5% to approximately 15% of said dielectric ink composition;

    (e) an additional amount of said polar solvent, wherein said additional amount of said polar solvent comprises approximately 10% to approximately 35% of said dielectric ink composition.
