Hybrid Aqueous Batteries: Atomic Engineering Catalyzed MnO₂ Electrolysis Kinetics for a Hybrid Aqueous Battery with High Power and Energy Density (Adv. Mater. 25/2020)

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).
