The disclosed technology generally relates to thin film-based energy storage devices, and more particularly to printed thin film-based energy storage devices. The thin film-based energy storage device includes a first current collector layer and a second current collector layer over an electrically insulating substrate and adjacently disposed in a lateral direction. The thin film-based energy storage device additionally includes a first electrode layer of a first type over the first current collector layer and a second electrode layer of a second type over the second current collector layer. A separator separates the first electrode layer and the second electrode layer. One or more of the first current collector layer, the first electrode layer, the separator, the second electrode layer and the second current collector layer are printed layers.

Thin film-based energy storage devices

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.

Printed energy storage device

A conductive ink may include a nickel component, a polycarboxylic acid component, and a polyol component, the polycarboxylic acid component and the polyol component being reactable to form a polyester component. The polyester component may be formed in situ in the conductive ink from a polyol component and a polycarboxylic acid component. The conductive ink may include a carbon component. The conductive ink may include an additive component. The conductive ink may include nickel flakes, graphene flakes, glutaric acid, and ethylene glycol. The conductive ink may be printed (e.g., screen printed) on a substrate and cured to form a conductive film. A conductive film may include a nickel component and a polyester component.
