Due to the drawbacks in commercially known lithium-ion batteries (LIB) such as safety, availability, and cost issues, aluminum batteries are being hotly pursued in the research field of energy storage. Al being abundant, stable, and possessing high volumetric capacity has been found to be attractive among the next generation secondary batteries. Various unwanted side reactions in the case of aqueous electrolytes have shifted the attention toward nonaqueous electrolytes for Al batteries. Unlike LIBs, Al batteries are based on intercalation/deintercalation of ions on the cathode side and deposition/stripping of Al on the anodic side during the charge/discharge cycle of the battery. Hence, to provide a clear understanding of the recent developments in Al batteries, we have presented an overview concentrating on the choice of suitable cathodes and electrolytes involving aluminum chloride derived ions (AlCl , AlCl , AlCl, etc.). We elaborate the importance of innovation in terms of structure and morphology to improve the cathode materials as well as the necessary properties to look for in a suitable nonaqueous electrolyte. The significance of computational modeling is also discussed. The future perspectives are discussed which can improve the performance and reduce the manufacturing cost simultaneously to conceive Al batteries for a wide range of applications.
由于商业上已知的锂离子电池（LIB）存在诸如安全、可用性和成本等问题，铝电池在储能研究领域正受到热烈追捧。铝资源丰富、性质稳定且具有高体积容量，已被发现在下一代二次电池中颇具吸引力。水性电解质情况下的各种不良副反应已将人们的注意力转向铝电池的非水电解质。与锂离子电池不同，铝电池在电池的充电/放电循环过程中，基于阴极侧离子的嵌入/脱嵌以及阳极侧铝的沉积/剥离。因此，为了清晰了解铝电池的最新进展，我们呈现了一篇综述，重点关注涉及氯化铝衍生离子（AlCl 、AlCl 、AlCl等）的合适阴极和电解质的选择。我们阐述了在结构和形态方面进行创新以改善阴极材料的重要性，以及在合适的非水电解质中应具备的必要性能。还讨论了计算建模的意义。探讨了未来的前景，其可同时提高性能并降低制造成本，从而设想出适用于广泛应用的铝电池。
