1. A method of forming an electrochemical cell including a cathode, an anode, an electrolyte separator, comprised of a ceramic material, located between the cathode and the anode, and a cathode current collector, wherein the cathode is located between the cathode current collector and the electrolyte separator, the method comprising:
forming a solid or semi-solid cathode comprising a cathode active material, an electrolyte for the charge transfer ion, and an electron conducting material; and
inserting the solid or semi-solid cathode into a cathode receptive space of the electrochemical cell, wherein the cathode is configured to precisely fit into the cathode receptive space,
wherein an upper portion of the cathode receptive space is bounded by the cathode current collector to contact an upper surface of the cathode, a lower portion of the cathode receptive space is bounded by the electrolyte separator, and side portions of the cathode receptive space are bounded by low-porosity ceramic walls.
