1. A printed circuit board comprising:

  • a printed circuit board (PCB) layer stack having a plurality of layers which include two outer electrically insulating layers, with conductor traces being formed on one or both of the outer electrically insulating layers;

    wherein each of the two outer electrically insulating layers of the PCB layer stack comprises an insulator material disposed in a layer of epoxy material;

    wherein each of said two outer electrically insulating layers of the PCB layer stack has edges that comprise a respective perimeter of each of said two outer electrically insulating layers of the PCB layer stack; and

    an electrochemical cell structure inserted in said PCB layer stack between said two outer electrically insulating layers of the PCB layer stack, wherein said electrochemical cell structure is embedded between said two outer electrically insulating layers of said PCB layer stack, and wherein said electrochemical cell structure extends laterally beyond the respective perimeter of at least one of said two outer electrically insulating layers of the PCB layer stack.
