A paradigm high‐rate and high‐voltage affordable Zn–Mn hybrid aqueous battery (HAB) is constructed by Shi‐Zhang Qiao and co‐workers (article number 2001894). The fairytale depicts a cowherd (the Mn cathode) on the ground, and the weaving girl (the Zn anode) on the moon, who are separated (by a membrane). They can only express their love by the media of H + and OH − , which produce a streamlet and powers the moon (lamp bulb). The carrier pigeon (Ni) serves as a catalyst to speed‐up the process (reaction).
