Abstract
A battery may include a first electrode and a second electrode. In some examples, the first electrode may include a metal substrate including a major surface, where a plurality of tunnels extend into the major surface, and an electrode composition is deposited onto the major surface of the metal substrate, where a portion of the electrode composition is positioned within the plurality of tunnels. The battery may be positioned within a housing of an implantable medical device (IMD).
