The development of safe, cheap, and environmentally friendly advanced rechargeable batteries with high energy density are one of the most pressing tasks for today's energy crisis. With the advantages of low cost, abundant reserves, and high-level safety, rechargeable aluminum ion batteries are considered ideal candidates for next-generation energy storage batteries in the context of large-scale energy applications. Relevant knowledge of energy storage materials and electrolytes, which possess close connection in between, is undeniably crucial for such research, while ironically, most attention is attracted to merely one element alone, especially the energy storage materials involving micro/nanomaterials. In this review, we focus on cathode materials matching with various electrolyte systems for rechargeable aluminum batteries and manage to provide new ideas for the preparation methods of highefficiency electrochemical energy storage materials, with future outlooks in this field.

storage system, which would propel the substantial development of the energy storage technology. [4] In order to design high energy density storage devices, the identifying of host materials with high performance, especially elevated work potential, is essential. Due to the high electronegativity of oxygen, the metal oxides own strong ionic chemical bonds, which consequently result in increased plateau voltages. [5] Examples of such oxides owning potential high discharge voltages are amorphous V 2 O 5 (≈0.9 V), [6] MoO 2 (1.9 V), [7] TiO 2 (≈1.0 V) [8] and so on. Despite their advantage in working potential, they usually suffer from low capacity, discontented cycling life, and inferior rate capability, which originate from the slow reaction kinetics caused by the strong Coulombic interaction between the trivalent Al 3+ and oxide host lattice. [9] Previous researches have demonstrated that water molecules can be applied as "lubricant" to facilitate ions diffusion. [10] Typically, vanadyl phosphate dihydrate (VOPO 4 •2H 2 O) with a long intercalation chemistry history, has been recently developed as a potential cathode material for various alkali metalion batteries, meriting from its high redox reaction potential due to the strong inductive effect of [PO 4 ] tetrahedrons and the large interlayer space stemming from the interlayer water molecules. [11] Moreover, the easier multivalent ions (Mg 2+ and Zn 2+ ) intercalation into VOPO 4 •2H 2 O can take place with the aid of the water molecules. [11e,12] The study of vanadyl phosphate hydrate as AIBs cathode was first reported in 2020 by Wang and co-workers via fabricating a VOPO 4 -graphene heterostructure. [11f ] Although an improved cycling performance originating from its zero-strain property is achieved, the potential high discharge plateau voltage and capacity of vanadyl phosphate hydrate are underutilized. In addition, the effect and mechanism of the bonded water molecule content and its stability on the aluminum storage behavior have not been systematically studied.In this work, we select VOPO 4 •2H 2 O as a model cathode to reveal its Al 3+ storage behaviors. As expected, the VOPO 4 •2H 2 O presents high discharge plateau and holds high potential Al 3+ storage capacity. We further investigate the relationship between water content and electrochemical performance. Interestingly, our density functional theory (DFT) calculations results reveal that, compared with VOPO 4 •2H 2 O and VOPO 4 , the VOPO 4 •H 2 O possesses the lowest Al 3+ diffusion barrier and Al ion batteries (AIBs) are attracting considerable attention owing to high volumetric capacity, low cost, and high safety. However, the strong electrostatic interaction between Al 3+ and host lattice leads to discontented cycling life and inferior rate capability. Herein, a new strategy of employing water molecules contained VOPO 4 •H 2 O to boost Al 3+ migration via the charge shielding effect of water is reported. It is revealed that VOPO 4 •H 2 O with water lubrication effect and smaller steric hindrance ...
