Patent ID: 8841019

Claim:
An implantable medical device battery comprising: a first electrode; and a second electrode separate from the first electrode, the second electrode including: a first layer formed of a first material and having a first surface and a second surface, the first layer including a first section and a second section having a greater resistance than the first section and extending from the first surface toward the second surface, the second section extending from a perimeter of the second electrode to an interior of the second electrode, the second section including at least one slot extending through the first layer, wherein the second section is configured to at least partially segment a surface area of the second electrode to reduce a radial current loop size in the second electrode; and a second layer formed of a second material different from the first material and having a third surface and a forth surface, the third surface abutting the second surface of the first layer, the second layer including at least one tab extending from the third surface of the second layer and positioned within the at least one slot of the first layer, the at least one tab formed from a third material different from the first material; wherein the second material includes a conductive material and the third material includes a polymeric material.
