Abstract
A method for fabricating a stacked battery structure. The method includes preparing a plurality of battery layers separately, wherein each battery layer includes a substrate, a film battery element fabricated on the substrate and an insulator formed over the film battery element. The insulator has a flat top surface and the film battery element includes a current collector. The method also includes stacking the plurality of battery layers, wherein the insulator of a first battery layer of the plurality of battery layers bonds to the substrate of a second battery layer of the plurality of battery layers by the flat top surface. The method further includes forming a conductive path within the plurality of battery layers, wherein the conductive path connects with at least one of the current collectors of the plurality of battery layers.
