摘要： An alkali metal/solid cathode electrochemical cell, such as of a Li/SVO couple, having the cathode material supported on a titanium current collector screen coated with a carbonaceous material is described. The thusly-coated titanium current collector provides the cell with higher rate capability in comparison to cells of a similar chemistry having the cathode active material contacted to an uncoated titanium current collector.

摘要： An electrochemical cell comprising a conductive casing housing an electrode assembly provided with a stack holder surrounding the electrode assembly is described. The stack holder is of an elastic material that serves to maintain the anode and cathode in a face-to-face alignment throughout discharge. This is particularly important in later stages of cell life. As the cell discharges, anode active material is physically moved from the anode to intercalate with the cathode active material. As this mass transfer occurs, the cathode becomes physically larger and the anode smaller. This can lead to misalignment. However, the stack holder prevents such misalignment by maintaining a constrictive force on the electrode assembly throughout discharge.

摘要： A method for making an electrochemical device enclosure is described. The methods comprises the steps of forming first and second casing members; inserting electrochemically active materials within the first casing member; mating the first casing member to the second casing member, thereby forming an interface therebetween; providing a laser welding apparatus comprising a laser; intermittently turning a laser beam on and off while traversing the laser in a first welding pass 360 degrees along the perimeters of the first and second casing members, thereby forming a first intermittent set of welded and unwelded sections at the interface between the casing members; and intermittently turning the laser beam on and off while traversing the laser in a second welding pass 360 degrees along the perimeters of the first and second casing members, thereby forming a second intermittent set of welded sections at the interface between the first and second casing members. The first and second intermitted welded sections combine to provide a complete hermetic seal around and along the circumference of the casing members interface.
