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.

Tubular form biomedical device batteries

Device and methods for sealing and encapsulation for biocompatible energization elements are described. In some examples, the device and methods for sealing and encapsulation for biocompatible energization elements involve heat welding, laser welding, or both where a laminar structure is enclosed by a polymer film capable of sealing. In some examples, a field of use for the apparatus and methods may include any biocompatible device or product that requires energization elements.

Embodiments of the invention relate to a fuel source including a chemical hydride and at least one reactive metal source selected from the group consisting of a reactive metal, a reactive metalloid and a combination thereof.

Fuel source for electrochemical cell

Ozonated manganese dioxide is prepared by an ozonation process and utilized as a cathode active material. An ozone containing gas stream contacts manganese dioxide and produces ozonated manganese dioxide with high efficiency. After preparation, ozonated manganese dioxide is stored for a limited time at a low temperature and incorporated into a cathode active material for alkaline batteries.

Ozonating manganese dioxide

A wafer alkaline cell of a laminar structure is disclosed. The cell has a pair of opposing sides comprising at least the majority of the boundary surface of said cell and defining a short cell dimension therebetween. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. The cell comprises preferably two separate plastic frames housing the anode and cathode material. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The anode assembly has an anode material therein typically comprising zinc and the cathode assembly has a cathode material therein typically comprising manganese dioxide. The cell is durable and preferably rigid, has elongated leak block paths, and resists electrolyte leakage.

Electrochemical cell systems are provided. In some implementations, the electrochemical cell system includes a fuel cell and a fuel cartridge connected to the fuel cell. The fuel cell includes (i) a fuel cell housing having a first external surface and a first internal surface defining a first internal volume of the fuel cell housing, and (ii) a cathode, an anode, and an electrolyte disposed within the first internal volume. The fuel cartridge includes (i) a cartridge housing having a second external surface and a second internal surface defining a second internal volume of the cartridge housing, wherein the second internal volume includes a fuel; and (ii) a fuel consuming agent disposed on at least one of the first external surface and the second external surface.

Electrochemical cell systems comprising fuel consuming agents

A wafer alkaline cell of a laminar structure is disclosed. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. There may be one and desirably two anode frames securing an anode current collector sheet sandwiched therebetween. There may be a cathode frame bonded to the anode frames. There is an anode current collector sheet within the anode assembly. There is a cathode current collector sheet, optionally with an attached metal mesh embedded within the cathode assembly to assure good electrical contact with the cathode. Alternatively, a cathode endplate with spring action is employed which can move in response to changes of volume or pressure within the cathode, thereby maintaining good contact. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The cell is durable and preferably rigid and resists electrolyte leakage.
