“…In aqueous aluminum-ion batteries (AIBs), electrolyzing the anode in an aqueous electrolyte (4 < pH < 8) leads to the formation of Al 2 O 3 , accompanied by a reduction in electrode potential. The uneven corrosion of aluminum in the electrochemical reaction has limited the availability of relevant reports [ 26 – 29 ]. Compared to aluminum and magnesium anodes, zinc anodes exhibit a greater stability and a favorable redox potential of 0.76 V vs. SHE.…”

Aqueous zinc-ion batteries (AZIBs) are one of the most compelling alternatives of lithium-ion batteries due to their inherent safety and economics viability. In response to the growing demand for green and sustainable energy storage solutions, organic electrodes with the scalability from inexpensive starting materials and potential for biodegradation after use have become a prominent choice for AZIBs. Despite gratifying progresses of organic molecules with electrochemical performance in AZIBs, the research is still in infancy and hampered by certain issues due to the underlying complex electrochemistry. Strategies for designing organic electrode materials for AZIBs with high specific capacity and long cycling life are discussed in detail in this review. Specifically, we put emphasis on the unique electrochemistry of different redox-active structures to provide in-depth understanding of their working mechanisms. In addition, we highlight the importance of molecular size/dimension regarding their profound impact on electrochemical performances. Finally, challenges and perspectives are discussed from the developing point of view for future AZIBs. We hope to provide a valuable evaluation on organic electrode materials for AZIBs in our context and give inspiration for the rational design of high-performance AZIBs.

Rechargeable batteries have been regarded as a truly transformative technology, providing energy storage for portable electronics, power tools, and even electric vehicles. Unfortunately, the practical applications of new battery systems are postponed by some inevitable technical bottlenecks. Sometimes the technical know‐how gained from the current state‐of‐the‐art lithium‐based batteries is untransferable. Therefore, with the continuous development of chemistry, materials and physics, computational materials science has gradually become crucial in supporting the field of rechargeable batteries technically. In this review, brief overviews of computational methods are first presented for the research of battery materials. The study then summarizes the recent advances of computational techniques in assisting experimental analyses, elucidating reaction mechanisms, and exploring new materials. Finally, the challenges and perspectives for future computational research are prospected. This review is anticipated to stimulate design inspiration of novel materials and structures with the assistance of theoretical simulations toward advanced energy storage systems.

Aqueous aluminum‐ion batteries present a promising prospect for large‐scale energy storage applications, owing to the abundance, inherent safety, and the high theoretical capacity of aluminum. However, their voltage output and energy density are significantly hindered by challenges such as complex hydrogen evolution and uncontrollable solvation reactions. In this work, we demonstrate that water decomposition is restrain by increasing the electron density of water protons and increasing the dissociation energy of H2O through robust dipole interactions with highly polar dimethylformamide (DMF) molecules. Moreover, the incorporation of dimethyl methylphosphonate (DMMP) flame retardant effectively addresses the flammability risk arising from a substantial presence of organic additives The in‐depth study with experimental and theoretical simulations reveals that the water‐poor solvation structure with reduced water activity is achieved, which can (i) effectively mitigate undesired solvated H2O‐mediated side reactions on the Al anode; (ii) boost the de‐solvation kinetics of Al3+ while preventing cathode structural distortion; (iii) reduce the flammability of hybrid electrolytes. As a proof of concept, the Al//AlxMnO2 full cell employing a hybrid electrolyte demonstrate enhanced stability (deliver 335 mAh g‐1 while retaining 71% capacity for 400 cycles) compared to those with pure electrolyte.
