An electrochemical cell having plate electrodes (16) housed inside mating "clam shell" casing components (12,14). Also, the present casing design allows for indentation structures (30,32) in the casing components by virtue of them being stamped metal parts...

A method for synthesizing a mixture of epsilon -SVO and gamma -SVO by a two step raw materials mixing process, is described. gamma -SVO is the preferred SVO in terms of electrochemical performance, such as reduced Rdc growth and reduced or eliminated volta...

Lithium electrochemical cells having a sandwich cathode electrode of SVO/CFx/SVO active materials are described. Such a design improves the service life of defibrillator electrochemical cells. A preferred formulation uses gamma -SVO/CFx/ gamma -SVO or ( ga...

A protection device and a method for protecting an electrical component. The protection device has a protective housing (11) and a terminal cap. The protective housing (11) has a base (12) with a contact hole (55) therethrough for receiving an electrical t...

A "fuel gauge" for a pulse dischargeable alkali metal/solid cathode cell is described. The rate of voltage recovery is used to determine the state of charge of the cell. Voltage recovery includes recovery from one load to a second, lighter load, or a loade...

A rechargeable lithium-ion cell capable of being discharged to deliver high power pulses sufficient for implantable defibrillation applications and the like, is described. The cell is housed in a casing having an external volume of 5 cm, or less. Both the ...

A mixed metal oxide, such as silver vanadium oxide, prepared by sequential decomposition and combination reactions is described. In the case of silver vanadium oxide, the product material is produced from a decomposable salt of silver and vanadium oxide fi...

A lithium ion electrochemical cell having high charge/discharge capacity, long cycle life and exhibiting a reduced first cycle irreversible capacity, is described. The stated benefits are realized by the addition of at least one sulfate additive to an elec...

The present invention includes a housing having a casing (13) and a cap (39). A connecting conductor is joined to the cap, and a plunger conductor (42) assembly is electrically connected to the connecting conductor. A battery may be placed in the casing an...
