Conductive primer compositions for a non-aqueous electrolyte electrical energy storage device

A conductive primer composition for use on a current collector within an electrical energy storage device containing a non-aqueous electrolyte, said conductive primer composition comprising:

• water;
• one or more organic polymers dissolved and/or dispersed in the water;
• and
• conductive particles dispersed in the water;
• wherein at least one of said one or more organic polymers comprises at least 70 wt % in total of monomers selected from the group consisting of acrylamide, n-methylol acrylamide, methacrylamide, n-methylol methacrylamide, vinylformamide, n-methylol vinylformamide, acrylic acid and methacrylic acid and comprises phosphorus acid bound to said at least one of said one or more organic polymers in an amount of 0.025-10.0% by weight.

A conductive coating composition for electrical energy storage devices containing a non-aqueous electrolyte, said conductive coating composition comprising:

• an organic binder;
• an active material;
• conductive particles dispersed in the organic binder;
• an organic polymer bearing phosphorus based acid, present in a range of 0.05-2.0% by weight of said organic polymer, different from the organic binder,
• wherein said organic polymer comprises at least 70% by weight of one or more monomers selected from the group consisting of acrylamide, n-methylol acrylamide, methacrylamide, n-methylol methacrylamide, vinylformamide, n-methylol vinylformamide, acrylic acid, and methacrylic acid;
• and present in a range of 0.1-5.0% total dry solids weight based on the conductive coating composition.

A coated current collector for use within an electrical energy storage device containing a non-aqueous electrolyte, said coated current collector comprising:

• A) a conductive metal surface;
• and
• B) a conductive primer layer adhered directly to the conductive metal surface;
• wherein said conductive primer layer comprises conductive particles and an organic polymeric binder comprising one or more organic polymers wherein at least one of said one or more organic polymers comprises 70% by weight or more of monomers selected from the group consisting of acrylamide, n-methylol acrylamide, methacrylamide, n-methylol methacrylamide, vinylformamide, n-methylol vinylformamide, acrylic acid and methacrylic acid and comprises phosphorus acid bound to said at least one of said one or more organic polymers in an amount of 0.025-10.0% by weight of a total amount of said one or more organic polymers.
