Abstract
Designs, strategies and methods for forming tube shaped batteries are described. In some examples, hermetic seals may be used to seal battery chemistry within the tube-shaped batteries. This may improve biocompatibility of energization elements. In some examples, the tube form biocompatible energization elements may be used in a biomedical device. In some further examples, the tube form biocompatible energization elements may be used in a contact lens.
Claims11
A battery comprising:
- an anode current collector, wherein the anode current collector is a first metallic tube closed on a first end;
- an anode, wherein the anode chemistry is contained within the first metallic tube;
- a cathode current collector, wherein the cathode current collector is a second metallic tube closed on a second end;
- a cathode, wherein the cathode chemistry is contained within the second metallic tube;
- a ceramic tube with a first sealing surface that sealably interfaces with the first metallic tube and a second sealing surface that sealably interfaces with the second metallic tube;
- and
- a sealing material located in a gap between the first sealing surface and first metallic tube, wherein the sealing material comprises a first layer comprising molybdenum and manganese particles in a mixture with ceramic powders which is then plated with a metallic film.
