Abstract
An encapsulation is provided on a flexible printed circuit board, comprising a top and a bottom electrically insulating base film, a top electrically conductive metal layer over the top electrically insulating base film, and a bottom electrically conductive metal layer under the bottom electrically insulating base film. A printable lithium ion battery is fabricated in a cavity completely through the top and bottom base films wherein a top of the battery contacts the top electrically conductive metal layer and wherein a bottom of the battery contacts the bottom electrically conductive metal layer. An adhesive film is fabricated around the battery to seals it to the top and bottom electrically insulating base film and to seals the top electrically conductive metal layer to the bottom electrically conductive metal layer.
