Battery assembly for medical device

Abstract

In some example, a battery assembly for an implantable medical device includes a first anode plate comprising a first anode current collector and a first active material on the first anode current collector; a second anode plate comprising a second anode current collector and a second active material on the second anode current collector; and a cathode plate between the first anode plate and the second anode plate, wherein the cathode plate comprises a cathode current collector, the cathode current collector having an exposed portion, wherein the first active material is recessed relative to the exposed portion of the cathode plate such that a first nearest perimeter of the first active material is further from the exposed portion of the cathode current collector compared to a second nearest perimeter of the second active material.
