  • Patent number: 11791468
    Abstract: An electrode material useful as a dry in place deposit comprising at least one metal chelating polymer; an active material capable of reversibly intercalating lithium ions; a plurality of electrical conductor particles; a binder polymer. The electrode material is formed into a slurry using a non-aqueous solvent. The metal chelating polymer may be a reaction product of a polyphenolic polymer; an aldehyde, a ketone, or mixtures thereof; and an amine. The electrode material slurry is deposited on a current collector and dried to form a positive electrode in a secondary lithium ion battery. The deposited electrode material has high flexibility, adhesion to the current collector, resistance to electrolyte damage, and low electrical resistance. The electrode material forms a superior positive electrode at a relatively low additional cost and with no increase in process complexity.

  • Patent number: 9819023
    Abstract: A conductive coating composition for use in electrical energy storage devices, which contain a non-aqueous electrolyte, is provided comprising an organic polymeric binder comprising one or more water-soluble polymers; water; solid conductive particles dispersed in the binder; and phosphorus based acid bound to at least one of the water-soluble polymers and present in a range of 0.025-10.0% by weight of the water-soluble polymers, as well as methods of making and using said conductive coating composition, coated current collectors and electrical energy storage devices made therefrom.

  • Patent number: 9469903
    Abstract: Disclosed is a neutral to alkaline inorganic conversion coating composition that can be applied directly to a metal surface without a phosphatizing pre-treatment and that provides significant corrosion protection to the surface. The coating composition is very versatile and can accommodate addition of a wide variety of organic polymers which can be added directly to the coating composition thus eliminating multistep coating processes.

  • Publication number: 20110117381
    Abstract: Disclosed is a neutral to alkaline inorganic chrome-free conversion coating composition that can be applied directly to a metal surface without a phosphatizing pre-treatment and that provides significant corrosion protection to the surface. The conversion coating composition preferably has a pH of from about 6 to 11 and more preferably from 8 to 10. The coating composition includes at least one element from group IVB of the Periodic table and at least one element from group VB of the Periodic Table. Preferably, the coating composition includes from 1 to 7% by weight of the at least one element from group IVB and from 0.20% to 2.00% by weight of the at least one element from group VB. The conversion coating composition is a dry in place coating and being chrome free it does not have the environmental issues associated with chrome-based coatings.
