Abstract
A printed energy storage device includes a first electrode including zinc, a second electrode including manganese dioxide, and a separator between the first electrode and the second electrode, the first electrode, second, electrode, and separator printed onto a substrate. The device may include a first current collector and/or a second current collector printed onto the substrate. The energy storage device may include a printed intermediate layer between the separator and the first electrode. The first electrode, and the second electrode may include 1-ethyl-3-methylimidazolium tetrafluoroborate (CmimBF). The first electrode and the second electrode may include an electrolyte having zinc tetrafluoroborate (ZnBF) and 1-ethyl-3-methylimidazolium tetrafluoroborate (CmimBF). The first electrode, the second electrode, the first current collector, and/or the second current collector can include carbon nanotubes. The separator may include solid microspheres.
