Interlayer Engineering of α-MoO₃ Modulates Selective Hydronium Intercalation in Neutral Aqueous Electrolyte.

ABSTRACT: Among various charge-carrier ions for aqueous batteries, non-metal hydronium (H₃ O⁺ ) with small ionic size and fast diffusion kinetics empowers H₃ O⁺ -intercalation electrodes with high rate performance and fast-charging capability. However, pure H₃ O⁺ charge carriers for inorganic electrode materials have only been observed in corrosive acidic electrolytes, rather than in mild neutral electrolytes. Herein, we report how selective H₃ O⁺ intercalation in a neutral ZnCl₂ electrolyte can be achieved for water-proton co-intercalated α-MoO₃ (denoted WP-MoO₃ ). H₂ O molecules located between MoO₃ interlayers block Zn²⁺ intercalation pathways w
