Orthorhombic MoO3 (α‐MoO3) with multivalent redox couple of Mo6+/Mo4+ and layered structure is a promising cathode for rechargeable aqueous Zn‐ion batteries (AZIBs). However, pure α‐MoO3 suffers rapid capacity decay due to the serious dissolution and structural collapse. Meanwhile, the growth of byproduct and dendrite on the anode also lead to the deterioration of cyclic stability. This article establishes...
