Abstract

Methods and apparatus to form biocompatible energization elements are described. In some embodiments, the methods and apparatus to form the biocompatible energization elements involve forming cavities comprising active cathode chemistry. The active elements of the cathode and anode are sealed with a laminate stack of biocompatible material. In some embodiments, a field of use for the methods and apparatus may include any biocompatible device or product that requires energization elements.

Claims

1. An apparatus for powering a biomedical device, the apparatus comprising:

a laminate battery device with multiple energization elements for a biomedical device including powered components, comprising;

a cathode spacer layer, wherein the cathode spacer layer comprises a laminar construct core located adjacent to at least a first laminar construct adhesive 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 the first laminar construct adhesive layer 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 first cavity;

a second cavity between sides of the first hole and a first surface of the separator layer, wherein the second cavity is filled with cathode chemicals within the second cavity;

a first independent interconnect, wherein the first independent interconnect is in electrical connection with the cathode chemicals within the second cavity;

a second independent interconnect, wherein the second independent interconnect is physically segmented from the first independent interconnect and is in electrical connection with cathode chemicals within a third cavity;

wherein the third cavity is within a second hole located in the cathode spacer layer; and

an interconnect junction element, wherein the interconnection junction element makes electrical connection to the first current collector, the first independent interconnect, and the second independent interconnect, wherein an electrical diode within the interconnect junction element makes connection to at least one of the first current collector, the the first independent interconnect, and the second independent interconnect.
