摘要： The present invention relates to a method for the polymerization in an aqueous medium of monomers, and especially of fluoromonomers, using non-fluorinated surfactants; and the fluoropolymers formed therefrom. Specifically, the method of the polymerization uses one or more non-fluorinated surfactants selected from the group consisting of polyvinylphosphonic acid, polyacrylic acids, polyvinyl sulfonic acid, and salts thereof. Additionally, the use of polyvinylphosphonic acid, polyacrylic acids, polyvinyl sulfonic acid as surfactants in aqueous free radical polymerization is also novel.

摘要： The invention relates to an aqueous fluoropolymer, and preferably polyvinylidene fluoride (PVDF), composition for manufacturing electrodes for use in non-aqueous-type electrochemical devices, such as batteries and electric double layer capacitors. The composition contains aqueous PVDF binder, and one or more powdery electrode-forming materials. In one embodiment, the composition is free of fluorinated surfactant In another embodiment, one or more fugitive adhesion promoters are added. The electrode formed from the composition of the invention exhibits interconnectivity and irreversibility that is achieved from the use of aqueous PVDF binder.

摘要： The invention relates to a high shear stable aqueous fluoropolymer coating composition, preferably using polyvinylidene fluoride (PVDF), such as KYNAR® PVDF, suitable for high performance coating applications. The composition is based on a high shear stable fluoropolymer emulsion having small particle size, blended with an acrylic polymer additive. The use of this composition allows high bake PVDF water-base coatings which can be applied on variety of substrates such as metal or ceramic surfaces, and in the impregnation of textiles, glass, carbon or aramid fibers, etc. The dry coating formed from the coating composition of the invention exhibits improved gloss, crack resistance, chemical resistance, hot dirt pick up resistance and other improved properties.

摘要： 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.
摘要翻译：本发明涉及集成电极分离器（IES），以及它们在锂离子电池中作为自立式分离器的替代品的用途。 IES的结果是用含氟聚合物水基乳液或悬浮液涂覆电极，并干燥涂层以在电极上产生坚韧的多孔隔离层。含氟聚合物水性涂料可以任选地含有分散的无机颗粒和其他添加剂以提高电极性能，例如更高的离子传导或更高的温度使用。 IES提供了几个优点，包括更薄，更均匀的隔离层，以及取消单独的电池组件（分隔膜），以实现更简单，更节省成本的制造工艺。含水隔膜涂层可以与溶剂铸塑电极以及水性铸塑电极结合使用，或者以两个单独的工艺步骤或一步工艺。
