Methods and apparatus to form biocompatible energization primary elements for biomedical device

A biocompatible energization element comprising:

• a cathode spacer layer;
• a first hole located in the cathode spacer layer;
• a first current collector coated with anode chemicals, wherein the first current collector is attached to a first surface of the cathode spacer layer, and wherein a first cavity is created between sides of the first hole and a first surface of the first current collector coated with anode chemicals;
• a separator layer, wherein the separator layer is formed within the first cavity after a separator precursor mixture is dispensed into the cavity;
• a second cavity between an outside surface of the separator layer upon sides of the first hole and a first surface of the separator layer, wherein the first surface of the separator layer is the top of the separator layer at the bottom of the first cavity, wherein the second cavity is filled with cathode chemicals;
• a second current collector, wherein the second current collector is in electrical connection with the cathode chemicals;
• and
• an electrolyte comprising electrolyte chemicals, wherein the cathode chemicals, anode chemicals and electrolyte chemicals are formulated for a single discharging cycle of the energization element.
