Abstract
An energy storage device includes a printed current collector layer, where the printed current collector layer includes nickel flakes and a current collector conductive carbon additive. The energy storage device includes a printed electrode layer printed over the current collector layer, where the printed electrode layer includes an ionic liquid and an electrode conductive carbon additive. The ionic liquid can include 1-ethyl-3-methylimidazolium tetrafluoroborate (CmimBF). The current collector conductive carbon can include graphene and the electrode conductive carbon additive can include graphite, graphene, and/or carbon nanotubes.
