1. An apparatus, comprising:
- an implantable device housing;
electronics disposed in the implantable device housing;
a battery disposed in the implantable device housing, the battery comprising;
a battery housing;
an annular anode connected to a first terminal; and
a cathode connected to a second terminal and disposed around the anode,wherein the anode and the cathode are arranged in a bobbin configuration,wherein the implantable device housing defines an implantable housing interior shaped to conform to an implantable housing exterior having modeled fluid dynamics, and the battery housing defines a contoured interior and a battery housing exterior, wherein the anode and cathode are shaped to conform to the contoured interior of the battery housing and the battery housing exterior is shaped to conform to the implantable housing interior.

Abstract
One example includes a battery that includes a stack of at least one substantially planar anode and at least one substantially planar cathode, wherein the stack defines a contoured exterior, and a battery housing enclosing the stack, the battery housing defining a battery housing exterior, wherein the contoured exterior of the stack is shaped to conform to a contoured interior of the battery housing that approximately conforms to the battery housing exterior, the battery produced by the process of modeling, using fluid dynamics, an exterior of a biocompatible housing and shaping the battery housing to conform to at least some of the exterior of the biocompatible housing.
