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.

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.

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.
