“…These results indicate that the graphite coating layer greatly impacts the plating/stripping behaviours and improves the electrochemical reversibility of the Al anode. The electrochemical performances of state-of-the-art Al anodes are listed in Table S1 † 10,22,37,39–44 . It is found that our Al-g anode shows competitive electrochemical performances.…”

“…Figure 3f summarizes overpotentials of various anodes in existing literatures. [13][14][15][33][34][35][36][37] Impressively, the overpotentials of Mo@NG-Al, especially at high current densities, were lower than those of reported anodes, highlighting the more rapid desolvation kinetics on Mo@NG-Al. All the above results suggested that the introduction of dual-functional Mo nanoparticles with (110) preferred orientation significantly promoted the reversible plating/stripping process.…”

Constructing robust anode with strong aluminophilicity and rapid desolvation kinetics is essential for achieving high utilization, long‐term durability, and superior rate performance in Al metal‐based energy storage, yet remains largely unexplored. Herein, molybdenum nanoparticles embedded onto nitrogen‐doped graphene (Mo@NG) are designed and prepared as Al host to regulate the deposition behavior and achieve homogeneous Al plating/stripping. The monodispersed Mo nanoparticles reduce the desolvation energy barrier and promote the deposition kinetics of Al. Additionally, Mo nanoparticles act as aluminophilic nucleation sites to minimize the Al nucleation overpotential, further guiding uniform and dense Al deposition. As a result, the dual‐functional Mo@NG endows Al anodes with low voltage hysteresis, reversible Al plating/stripping with high coulombic efficiency, and excellent high‐rate capability under 5 mA cm−2. Moreover, the as‐designed Al metal full batteries deliver a high capacity retention of 92.8% after 3000 cycles at 1 A g−1. This work provides an effective solution to optimize the electrochemical properties of Al metal anode from the perspective of desolvation and deposition reactions, towards the development of high‐safety and long‐cycling aluminum‐ion batteries.

“…28 The AMA reaction kinetics are highly affected by the transfer rate of Al 2 Cl 7 − from the electrode surface because the local anion concentration sharply increases with the Al 3+ reduction reaction. 29 Therefore, a stereoscopic electrode design aimed at a greater active surface area and improved product anion transfer rate is key to developing high-performance AMAs. 30,31 However, many challenges in using AMAs, such as large volume change, unexpected dendritic metal growth, and severe morphological changes caused by the Lewis acidic ILE, persist, which significantly deteriorates the electrochemical performances of Al-DIBs.…”
