    摘要: An electrochemical cell having a cell package made of a metallic material to allow the cell package to be sealed by welding, even when contaminated. The electrochemical cell further includes an electrode cell stack and a metallic cell package having a base portion and a lid portion which are welded to each other (peripheral seam) to define an enclosure. The cell package includes a first section for receiving the cell stack and a second section having an inlet port and a degassing port which communicate with the first section. The lid portion is welded to the base portion to form a weld seam located between the first and second sections to seal off the first section from the second section. The weld seam extends from the peripheral seam on a first side of the cell package to the peripheral seam on a second side of the cell package.

    摘要: A secondary, solid electrolytic battery includes a number of electrically connected electrolytic cells wherein for each cell the anode and cathode are separated from each other by a mask that is a layer of electrically insulative material that is coated along the perimeter of the anode and/or cathode. The mask reduces the rate of dendrite formation and prevents edge-effects, short circuits, and related problems caused by inadvertent contact of the anode and cathode.

    摘要: A solid electrolyte that includes a complexing agent that is incorporated into the solid matrix provides for more effective transfer of current in an electrochemical cell or battery. The complexing agent immobilizes anions in the solid electrolyte so that at least a substantial majority of the charge transport is due to the cations, e.g., lithium ions. Preferred complexing agents are derived from aza-ethers. With the inventive solid electrolyte, it is expected that the lithium transference number should approach unity.

    摘要: In accordance with the invention, a new cathode composition is prepared in a preferred method, in situ, in a cell whereby such in situ formation results in enhanced contact between the cathode composition and the current collector and between the electrolyte layer and the cathode composition.The new cathode composition of the invention comprises first and second polymeric materials, the first being radiation cured and ionically conductive and the second being electrochemically cured and electrically conductive. Preferably, the first is radiation cured before the second is electrochemically cured. The second polymeric material is cured in an electrochemical cell which comprises an alkali metal-containing anode layer. The cell desirably contains an electrolyte which consists of a solid ionically conductive polymeric material.

    摘要: In a new process for making an electrode current collector assembly, an electrode composition is mixed with a volatile casting solvent and is coated onto a substrate. Then, the coated substrate is heated to drive off a major portion of the volatile casting solvent. Next, force is applied on an external surface of the coating and directed toward the substrate so as to compact the coating and reduce the volume of pore spaces in the coating. An electrolyte composition may be applied to the compacted electrode composition either before or after curing. The electrode and electrolyte compositions are each cured. In a final step, a counter-electrode layer is applied onto the electrolyte composition to form a cell assembly.

    摘要: A method of increasing the amount of alkali metal that is available during charge/discharge of an electrochemical cell that employs carbon based intercalation anodes is provided. The method comprises of prealkaliation of the carbon anode. By subjecting the anode carbon to the prealkaliation process prior to packaging the electrochemical cell, substantially all the alkali metal (e.g., lithium) which is originally present in the cathode will be available for migration between the anode and cathode during charge/discharge.
