1. A biostimulator comprising:
a battery assembly including a cell can containing an electrolyte;
an attachment feature coupled to the battery assembly, wherein the attachment feature includes a stem having an annular stem wall extending around an internal cavity, wherein the stem extends between a base and a button, wherein the button includes a proximal button face having a face port extending into the internal cavity, and wherein the button includes an exterior surface and an interior surface around the internal cavity; and
a low-polarization coating on the exterior surface and on a portion of the interior surface of the button, wherein the low-polarization coating effectively enlarges an electrode surface area of the button.
