1. A solid state electrode of an electrochemical device comprising:

  • a first plurality of particles of electrochemically active material, the first plurality of particles having a first particle size distribution characterized by a first dispersity of 0.25 or less and a first median diameter; and

    a second plurality of particles of ion conductive material, the second plurality of particles having a second particle size distribution characterized by a second dispersity of 0.25 or less and a second median diameter, the second median diameter being at least three times smaller than the first median diameter;

    wherein the electrode is characterized by a porosity of less than 10% by volume.
