Patent number: 11133562Abstract: The invention relates to integrated electrode separators (IES), and their use in lithium ion batteries as replacements for free standing separators. The IES results from coating an electrode with a fluoropolymer aqueous-based emulsion or suspension, and drying the coating to produce a tough, porous separator layer on the electrodes. The aqueous fluoropolymer coating may optionally contain dispersed inorganic particles and other additives to improve electrode performance such as higher ionic conduction or higher temperature use. The IES provides several advantages, including a thinner, more uniform separator layer, and the elimination of a separate battery component (separator membrane) for a simpler and cost-saving manufacturing process. The aqueous separator coating can be used in combination with a solvent cast electrode as well as an aqueous cast electrode either in two separate process steps, or in a one-step process.Type: GrantFiled: November 1, 2013Date of Patent: September 28, 2021Assignee: Arkema Inc.Inventors: John Schmidhauser, Scott R. Gaboury, Ramin Amin-Sanayei, Christophe Roger, Wensheng He, Rosemary Heinze

Patent number: 10399892Abstract: The invention relates to an aqueous fluoropolymer coating composition for direct application to glass without the need for pre-treatment of the glass surface. The coating composition can also be used with other non-porous and porous substrates. The fluoropolymer coating contains a hydroxyl-functional fluoropolymer, and polyisocyanates. Preferably the coating composition also contains a water-dispersible hydroxyl functional polyurethane. The coating composition may exist as a 1-pack or a multi-pack coating system. The coating has excellent wet adhesion to glass, good weathering, chalking resistance, chemical resistance, and dirt pickup resistance.Type: GrantFiled: April 2, 2013Date of Patent: September 3, 2019Assignee: Arkema Inc.Inventors: Min Zheng, Mei Wen, Scott R.

Patent number: 10392298Abstract: The invention relates to an intertwined multilayer primer/fluoropolymer coating on the glass substrate. The final coating has excellent wet adhesion to glass, good weathering, durability, chalking resistance, chemical resistance, and dirt pickup resistance. The coating is an environmentally friendly aqueous, fluoropolymer coating composition. The coating process involves applying a polyurethane primer to the glass substrate, and partially, but not completely crosslinking this primer coating. An aqueous hydroxyl-functional fluoropolymer coating is then applied to the partially cross-linked primer coating, and the coating allowed to fully cure. The invention also relates to the intertwined multilayer primer/fluoropolymer coating on the glass substrate. The final coating has excellent wet adhesion to glass, good weathering, durability, chalking resistance, chemical resistance, and dirt pickup resistance.Type: GrantFiled: June 28, 2017Date of Patent: August 27, 2019Assignee: ARKEMA INC.Inventors: Min Zheng, Mei Wen, Scott R.

Patent number: 9799917Abstract: This invention relates to a waterborne fluoropolymer composition useful for the fabrication of Li-ion-Battery (LIB) electrodes. The fluoropolymer composition contains an organic carbonate compound, which is more environmentally friendly than other fugitive adhesion promoters currently used in waterborne fluoropolymer binders. An especially useful organic carbonate compound is ethylene carbonate (EC) and vinylene carbonate (VC), which are solids at room temperature, and other carbonates which are liquid at room temperature such as propylene carbonate, methyl carbonate and ethyl carbonate. The composition of the invention is low cost, environmentally friendly, safer, and has enhanced performance compared to current compositions.Type: GrantFiled: January 18, 2016Date of Patent: October 24, 2017Assignee: Arkema Inc.Inventors: Ramin Amin-Sanayei, Scott R.

Publication number: 20150030906Abstract: The invention relates to a separator for non-aqueous-type electrochemical device that has been coated with an aqueous fluoropolymer coating. The fluoropolymer is preferably polyvinylidene fluoride (PVDF), and more preferably a copolymer of polyvinylidene fluoride. The fluoropolymer coating provides a porous coating on porous substrate separator used in non-aqueous-type electrochemical devices, such as batteries and electric double layer capacitors. The fluoropolymer coating improves the thermal resistance and mechanical integrity, and lowers the interfacial electrical impedance of the porous separator. The fluoropolymer composition optionally contains powdery particles that are held together on the separator by the fluoropolymer binder. In one embodiment, the starting fluoropolymer dispersion is free of fluorinated surfactant. In another embodiment, one or more fugitive adhesion promoters are added.Type: ApplicationFiled: February 21, 2013Publication date: January 29, 2015Inventors: Ramin Amin-Sanayei, Scott R. Gaboury
