Abstract
A flexible printed circuit board with a lithium ion battery printed thereon is achieved. The flexible printed circuit board comprises 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 sits 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 around the battery seals it to the top and bottom electrically insulating base film and seals the top electrically conductive metal layer to the bottom electrically conductive metal layer.
