Claims
- 1. A method of manufacturing a flat capacitor stack, comprising:
forming a plurality of capacitor layers, each capacitor layer including a separator layer attached to a capacitor foil layer; and placing each of the plurality of capacitor layers onto a capacitor stack by aligning each of the capacitor layers using an outer edge of the separator layer of the capacitor layer as an alignment means.
- 2. The method of claim 1, wherein aligning includes positioning the separator layer such that two or more points on an outer edge of the separator layer contact two or more corresponding alignment members.
- 3. The method of claim 1, further comprising pressing the capacitor stack to a specified, predetermined height after the capacitor stack has been formed.
- 4. The method of claim 1, further comprising annealing the capacitor stack after the capacitor stack has been formed.
- 5. The method of claim 1, wherein placing each of the plurality of capacitor layers includes:
providing an alignment mechanism; and placing each capacitor layer within the alignment mechanism such that an outer edge of each separator layer contacts one or more alignment members of the alignment mechanism.
- 6. The method of claim 1, wherein forming a plurality of capacitor layers includes forming a first anode stack having or more anode layers and having a first surface area, and forming a second anode stack having or more anode layers and having a second surface area, wherein the first surface area is greater than the second surface area.
- 7. The method of claim 6, wherein the second anode stack has one or more less anode layers than the first anode stack.
- 8. A flat capacitor having a capacitor stack formed by a method including:
forming a plurality of capacitor layers, each capacitor layer including a separator layer attached to a capacitor foil layer; and placing each of the plurality of capacitor layers onto a capacitor stack by aligning each of the capacitor layers using an outer edge of the separator layer of the capacitor layer as an alignment means.
- 9. The flat capacitor of claim 8, wherein aligning the separator layer includes positioning the separator layer such that two or more points on an outer edge of the separator layer contact two or more corresponding two or more alignment members.
- 10. The flat capacitor of claim 8, further comprising pressing the capacitor stack to a specified, predetermined height.
- 11. The flat capacitor of claim 8, further comprising annealing the capacitor stack.
- 12. The flat capacitor of claim 8, wherein aligning each of the plurality of capacitor layers includes:
providing an alignment mechanism; and placing each capacitor layer within the alignment mechanism such that an outer edge of each separator layer contacts one or more alignment members of the alignment mechanism.
- 13. The flat capacitor of claim 8, wherein at least one of the plurality of capacitor layers includes a first anode stack having or more anode layers and having a first surface area, and wherein at least one of the plurality of capacitor layers includes a second anode stack having or more anode layers and having a second surface area, wherein the first surface area is greater than the second surface area.
- 14. The flat capacitor of claim 13, wherein the second anode stack has one or more less anode layers than the first anode stack.
- 15. A method comprising:
cutting a capacitor foil layer out of a sheet of a foil with a laser; removing the foil layer shape from the sheet of foil; and inserting the foil layer shape into a capacitor stack.
- 16. The method of claim 15, wherein the capacitor foil layer is an anode foil layer.
- 17. The method of claim 15, wherein the capacitor foil layer is a cathode foil layer.
- 18. The method of claim 15, wherein the cutting is through multiple sheets at one time.
- 19. The method of claim 15, wherein the foil layer is separated by a separator layer from an adjacent foil layer.
- 20. The method of claim 15, further comprising installing the capacitor stack into a capacitor case.
- 21. The method of claim 20, further comprising installing the capacitor case into a medical device.
