Battery package including electrode having recessed region of electrode material layer exposing a portion of a conductive layer and method of making the same

In an implementation, an electrode is produced that includes a recessed region of an electrode material layer. The electrode can be part of a battery that provides power to an electronic device. The recessed region can expose a portion of a metal layer of the electrode. A tab can be coupled to the exposed portion of the metal layer. The tab can provide an external connection for the battery to provide power to components of the electronic device. The battery can be included in a battery package that includes a packaging material. A sealing material can be used to seal the tab at a location of the battery package where the tab extends beyond a periphery of the battery package.
