Patent ID: 8906534

Claim:
A device comprising: a battery layer on a topmost surface of a substrate, wherein no other portion of the substrate is positioned over the topmost surface of the substrate, wherein a first battery cell is formed in the battery layer, the first battery cell including: a first anode; a first cathode; and a first electrolyte arranged between the first anode and the first cathode, and wherein each one of the first anode, the first electrolyte, and the first cathode have a bottommost surface physically contacting the topmost surface of the substrate, wherein the first anode, the first cathode, and the first electrolyte have substantially coplanar top surfaces that face away from the topmost surface of the substrate, and wherein the battery layer further includes another anode associated with another battery cell, the another anode having a bottommost surface physically contacting the topmost surface of the substrate and the another anode physically contacting the first cathode.
