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.

钾电池：碳酸盐电解质中不含树突的钾金属阳极（Adv。Mater。7/2020）

David Mitlin及其同事在文章编号1906460中演示了碳酸盐电解质中无枝晶的钾金属阳极。在覆盖有缺陷石墨烯的海底巡航的defective鱼代表了钾金属电池（KMB）的阳极。黄貂鱼代表电镀的钾金属，它润湿了石墨烯的表面。就像黄貂鱼的自然身体形状一样，镀钾是平坦的。在自然界中，黄貂鱼留在底部附近觅食。
