Abstract
Passivation methods and compositions for electrode binders are disclosed. A coated binder particle for use in an electrode film of an energy storage device is provided. The coated binder particle can comprise a coating over the surface of a binder particle, wherein the coating provides ionic insulation to the binder particle. In some embodiments, the coating covers the entire surface of the binder particle. In still further embodiments, a coated binder particle in an energy storage device blocks ionic contact between the binder and an electrolyte.
