Patent number: 6228531Abstract: The present invention is directed to an electrode, and associated fabrication process, for use in an electrochemical cell. The electrode has an active material comprising a transition metal oxide. A lithium salt having an organic component is associated with the surface of the transition metal oxide so as to increase compatibility with an associated electrolyte. In another embodiment, a lithium salt of saccharin may be adsorbed onto the surface of the transition metal oxide.Type: GrantFiled: October 2, 1998Date of Patent: May 8, 2001Assignee: Mitsubishi Chemical CorporationInventors: Eric S.

Patent number: 6225008Abstract: A process for fabricating an electrode for use in an electrochemical cell comprising the steps of: a) associating a current collector with an active material having a surface; b) applying an overlayment material to a substrate; c) associating the overlayment material with at least a portion of the surface of the active material; d) at least alternatively partially curing the active material; and e) removing the substrate and, in turn transferring at least a portion of the overlayment material to at least a portion of the active material. The electrode produced is used in an electrochemical cell comprising a current collector, an electrode active material having a surface, and an overlayment material associated with at least a portion of the active material. The electrode further includes means for increasing compatability of the electrode with an associated electrolyte.Type: GrantFiled: October 29, 1998Date of Patent: May 1, 2001Assignee: Mitsubishi Chemical CorporationInventors: Eric S.

Patent number: 6168878Abstract: 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.Type: GrantFiled: December 10, 1998Date of Patent: January 2, 2001Assignee: Mitsubishi Chemical CorporationInventors: Denis G. Fauteux, Martin Van Buren, Eric S. Kolb

Patent number: 6110638Abstract: A process for generation of acid uses a medium comprising a first acid-generating component capable of generating a first acid, and a secondary acid generator, this secondary acid generator being capable of thermal decomposition to form a secondary acid, the thermal decomposition of the secondary acid generator being catalyzed by the first acid. At least part of the medium is exposed to so as to cause formation of the first acid from the first acid-generating component; and the medium is then heated to cause, in the exposed part of the medium, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid.Type: GrantFiled: November 27, 1996Date of Patent: August 29, 2000Assignee: Polaroid CorporationInventors: Roger A.

Patent number: 6080282Abstract: The present invention is directed to both an electrolyte solution for use as a gel electrolyte in an electrolytic cell, and a process for making both the electrolyte gel and the electrolytic cell. The electrolyte solution comprises a polymerizable electrolyte material and a reinforcement polymer. The reinforcement polymer preferably consists of at least poly(methyl methacrylate), while the polymerizable electrolyte material comprises at least a solvent, a monomer, a polymerization initiator, and an ionic conductor. The use of a reinforcement polymer increases the homogeneity and thus the coatability of the electrolytic solution, while also improving the mechanical properties of the cured electrolyte gel.Type: GrantFiled: April 22, 1998Date of Patent: June 27, 2000Assignee: Mitsubishi Chemical CorporationInventors: Eric S. Kolb, Martin Van Buren, Marina Sherman

Patent number: 6045937Abstract: 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.Type: GrantFiled: October 26, 1998Date of Patent: April 4, 2000Assignee: Mitsubishi Chemical CorporationInventors: Eric S. Kolb, Martin Van Buren, Denis G. Fauteux
