Patent ID: 8722233

Claim:
A roll comprising a plurality of electrical devices, each said electrical device comprising: an electrical apparatus including: an apparatus substrate having a first side and a second side, an electrical component provided on said first side of said apparatus substrate, a first electrical contact electrically connected to said electrical component and provided on said second side of said apparatus substrate, and a second electrical contact electrically connected to said electrical component and provided on said second side of said apparatus substrate; a flat battery including at least one electrochemical cell having a first printed electrochemical layer comprising a cathode layer including a first dried or cured ink and a second electrochemical layer comprising an anode layer, wherein both of the cathode layer and anode layer are at least partially covered by a same electrolyte layer in contact with both of the cathode layer and anode layer, and wherein both of the cathode layer and anode layer are provided on a same battery substrate layer such that the cathode layer and the anode layer are thereby arranged substantially co-planar, and wherein said battery having a first side and a second side, with said first side of said battery fixedly connected to said second side of said apparatus substrate, wherein said battery is for providing electrical energy to said electrical apparatus, said battery including: a first electrode contact connected to said first electrical contact, and a second electrode contact connected to said second electrical contact; and a first adhesive for mounting said second side of said battery to a flexible substrate; each of said plurality of electrical devices being adhered to a flexible substrate.
