Multifunctional polynorbornene binder system

A cathode electrode assembly is disclosed, the cathode electrode assembly comprising an active material, a current collector, a conductive additive substance, and a polynorbornene-based (PNB) polymer binder configured to bind the active material and the conductive additive substance and maintain electrical contact between the active material and the conductive additive substance with the current collector. An alternative cathode electrode assembly comprising active material, a current collector, a conductive additive substance, a PNB polymer binder, and at least one polyacrylic acid (PAA) side chain configured to interface with the PNB polymer binder is also disclosed. A functional group is further disclosed, the functional group being configured to interface with a binder in a cathode electrode assembly of an electric battery system, the functional group comprising at least one PAA side chain.
