Aqueous aluminum‐ion batteries are at an early development stage and there is a need to discover new electrode materials for the fabrication of high energy density devices. To address this issue, we investigate MoO 3 nanowires as a possible electrode material for use in rechargeable Al‐ion batteries that can operate in aqueous conditions. We present a hexagonal structure of MoO 3 microrods as an Al‐ion intercalation host material and show its first‐time use as a potential electrode for an aqueous Al‐ion battery system. This yields a discharge capacity of approximately 300 mAh g −1 for 150 cycles and around 90 % retention after 400 cycles at a current density of 3 A g −1 . The utilization of this type of material and aqueous electrolytes guarantees both safety during operation and simple recycling of spent batteries.
