Abstract: An electronic device includes a base substrate, and a plurality of battery substrates constructed from mica and being attached to the base substrate. An aggregate area of the base substrate is greater than an aggregate area of the plurality of battery substrates. The electronic device also includes a plurality of active battery layers, each active battery layer being attached to a different respective battery substrate, with each active battery layer having a smaller area than its corresponding battery substrate. A film is disposed over the plurality of active battery layers and sized such that the film extends beyond each active battery layer to contact each battery substrate, and such that the film extends beyond each battery substrate to contact the base substrate.

Abstract: A method for forming a microbattery including, on a surface of a first substrate, one active battery element and two contact pads, this method including the steps of: a) forming, on a surface of a second substrate, two contact pads with a spacing compatible with the spacing of the pads of the first substrate; and b) arranging the first substrate on the second substrate so that the surfaces face each other and that the pads of the first substrate at least partially superpose to those of the second substrate, where a portion of the pads of the second substrate is not covered by the first substrate.

Abstract: An electronic device includes a base substrate with a mica substrate thereon. A top face of the mica substrate has a surface area smaller than a surface area of a top face of the base substrate. An active battery layer is on the mica substrate and has a top face with a surface area smaller than a surface area of a top face of the mica substrate. An adhesive layer is over the active battery layer, mica substrate, and base substrate. An aluminum film layer is over the adhesive layer, and an insulating polyethylene terephthalate (PET) layer is over the aluminum film layer. A battery pad is on the mica substrate adjacent the active battery layer, and a conductive via extends to the battery pad. A conductive pad is connected to the conductive via. The adhesive, aluminum film, and PET have a hole defined therein exposing the conductive pad.
