The main challenge for developing aqueous aluminum-air batteries with high mass-specific capacity depends on the inhibition of the parasitic hydrogen evolution reaction. Herein, a regulation strategy of solvation and interface chemistry has been proposed by introducing organic methylurea (MU) and inorganic stannous chloride (SnCl) to the alkaline electrolyte, which can modulate the solvent structure and electrode/electrolyte interface and endow the aqueous aluminum-air battery with an outstanding mass-specific capacity of 2625 mA h g at 50 mA cm.
开发具有高质量比容量的水系铝空气电池面临的主要挑战在于抑制寄生析氢反应。在此，通过将有机甲基脲（MU）和无机氯化亚锡（SnCl）引入碱性电解质中，提出了一种溶剂化和界面化学的调控策略，该策略可以调节溶剂结构和电极/电解质界面，并赋予水系铝空气电池在50 mA cm下2625 mA h g的出色质量比容量。
