More Information
Summary:An electrode conductive filler precursor dispersion is provided that includes a conductive carbon-based particle selected from the group consisting of: graphene nanoplatelet (GNP), carbon nanofibers (CNF), carbon nanotubes (CNT), and combinations thereof. A stabilizing polymer comprising polyvinyl-4-pyridine (PVPy). The dispersion also includes a solvent. The electrode conductive filler precursor dispersion is substantially free of syneresis for greater than or equal to about 7 days. Methods of making the electrode conductive filler precursor dispersion and electrodes from the electrode conductive filler precursor dispersion are also provided.
