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.
