Dendrite‐free potassium metal anodes in a carbonate electrolyte are demonstrated by David Mitlin and co‐workers in article number 1906460. Stingrays cruising an ocean floor covered with defective graphene represent the anode of a potassium‐metal battery (KMB). The stingrays represent the plating potassium metal, which wets the graphene surface. Just like the stingrays' natural body shape, the plating potassium is flat. In nature, the stingrays stay near the bottom to feed.
