In the search for sustainable energy storage systems, aluminum dual-ion batteries have recently attracted considerable attention due to their low cost, safety, high energy density (up to 70 kWh kg⁻¹), energy efficiency (80–90%) and long cycling life (thousands of cycles and potentially more), which are needed attributes for grid-level stationary energy storage. Overall, such batteries are composed of aluminum foil as the anode and various types of carbonaceous and organic substances as the cathode, which are immersed in an aluminum electrolyte that supports efficient and dendrite-free aluminum electroplating/stripping upon cycling. Here, we review current research pursuits and present the limitations of aluminum electrolytes for aluminum dual-ion batteries. Particular emphasis is given to the aluminum plating/stripping mechanism in aluminum electrolytes, and its contribution to the total charge storage electrolyte capacity. To this end, we survey the prospects of these stationary storage systems, emphasizing the practical hurdles of aluminum electrolytes that remain to be addressed.

在寻找可持续储能系统的过程中，铝双离子电池由于其低成本、安全、高能量密度（高达 70 kWh kg ⁻¹)、能源效率 (80–90%) 和长循环寿命（数千个循环甚至可能更多），这些都是电网级固定储能所需的属性。总的来说，这种电池由铝箔作为阳极和各种类型的碳质和有机物质作为阴极组成，它们浸入铝电解液中，支持在循环时高效和无枝晶的铝电镀/剥离。在这里，我们回顾了当前的研究进展，并提出了用于铝双离子电池的铝电解液的局限性。特别强调了铝电解质中的镀铝/剥离机制，及其对总电荷存储电解质容量的贡献。为此，我们调查了这些固定存储系统的前景，
