摘要： The present invention is directed to an electrolytic cell and associated process for fabrication, wherein the cell utilizes an intermediate sub-component connecting layer. This layer comprises an electrolyte which, in an at least partially cured state, is at least partially sandwiched between an electrolyte on a first sub-component and an electrolyte on a second sub-component. Prior to full curing of the intermediate sub-component connecting layer, the cell is oriented into a desired product configuration. Once such a configuration is obtained, the intermediate sub-component connecting layer is fully cured to, in turn, maintain the cell in the desired product configuration without concern of misalignment or mechanical degradation between the various sub-components and/or the cell.

摘要： An electrolytic cell and electrolytic process wherein the cell includes a metal anode (such as a lithium anode), a cathode and an electrolyte. A surface layer which is applied to the metal anode enables transfer of ions from the metal anode to the electrolyte and thus allows the ions to pass back into contact with the metal anode. The surface layer is also electronically conductive so that the ions will be uniformally attracted back onto the metal anode during electrodeposition to, in turn, substantially suppress dendrite growth and, in turn, substantially increase the cycle life of the cell.

摘要： An electrochemical cell, and an associated process, wherein the cell includes a controlled electrode surface comprising an electrode with a metallic current collector having a surface, an electrolyte and a reduced additive. The invention further includes a passivating layer at the interface between the metallic current collector and the electrolyte. The passivating layer includes the reduced additive. This passivating layer substantially precludes contact between electrolyte solvent and surface of the metallic current collector to, in turn, substantially prevent gas formation within the cell, which would otherwise result from decomposition of the solvent upon contact with the surface of the metallic current collector. Also, the reduced additive will likewise be substantially precluded from generating a gas upon its decomposition.

摘要： An electrolytic cell, such as a rechargeable lithium battery, having cavitands associated with a metal ion source-electrode and an electrolyte. The cavitands, which are anchored to the electrode by a polymer leash, are capable of releasably attracting particular ions, such as lithium ions, which are migrating from the electrolyte, toward the surface of the electrode during electrodeposition. The polymer leash serves to continuously maintain the cavitands at a predetermined distance away from the surface of the electrode, regardless of surface area fluctuations, typically caused during deposition and dissolution of the particular ions. Accordingly, the cavitands facilitate substantially uniform electrodeposition of the particular ions, which, in turn, substantially suppresses and/or controls the formation and growth of a passive film or layer, on the electrode surface, which may otherwise promote the formation of dendrites.

摘要： An electrochemical cell, and an associated process, wherein the cell includes a controlled electrode surface comprising an electrode with a carbonaceous surface, an electrolyte and a reduced additive. The reduced additive is formulated from an additive which is either soluble or insoluble in the solvated electrolyte prior to reduction. The invention further includes a passivating layer at the carbonaceous electrode/electrolyte interface. The passivating layer includes the additive and/or the reduced additive. This passivating layer substantially precludes contact between electrolyte solvent and the carbonaceous surface of the electrode to, in turn, substantially prevent gas formation within the cell, which would otherwise result from decomposition of the solvent upon contact with the carbonaceous surface. Also, the additive and/or the reduced additive will likewise be substantially precluded from generating a gas upon its decomposition.

摘要： The present invention is directed to an electrode mask for use in an electrolytic cell, and an associated process for fabricating such a cell with an electrode mask. The electrode mask is applied to a limited portion of the active material of at least one of the first and second electrodes so that the peripheral edge of the electrode mask and associated electrodes are in planer relationship with each other. In addition, the electrode mask can be applied in a manner which enables a fully fabricated electrolytic cell to be manufactured with any desired geometric configuration, merely by altering the electrode mask application pattern, and a die-cutter to cut an assembled cell in conformance with the applied pattern of the electrode mask.
