Patent ID: 8873220

Claim:
An apparatus comprising: an electrode; a separator stacked in alignment with the electrode; a first electrode assembly disposed in a stack with the electrode and the separator, the separator disposed between the electrode and the first electrode assembly to physically separate the electrode and the first electrode assembly, wherein the first electrode assembly includes: a first layer including a first conductive material deposited on a first substrate, the first substrate having a first substrate flexibility greater than a first material flexibility of the first material; and a second layer stacked with the first layer, the second layer including a second conductive material deposited on a second substrate, the second substrate having a second substrate flexibility greater than a second material flexibility of the second material; and an interconnect coupled to the first substrate and the second substrate to physically and electrically couple the first layer and the second layer of the stack, wherein the first substrate of the first layer and the second substrate of the second layer are proximate each other and between the first material and the second material, wherein the interconnect includes a conductive element disposed between the first substrate and the second substrate, where at least one of the first layer and the second layer includes a notch configured to expose the conductive element disposed between the first substrate and the second substrate.
