Abstract
Electrochemistry Because of its high abundance, low production cost, and three-electron redox properties, aluminum (Al) has received considerable attention in recent years for the development of possible alternatives to conventional lithium-based batteries. Yan et al. propose an aqueous Al-ion battery configuration consisting of an Al x MnO2 cathode, a zinc substrate–supported Zn-Al alloy anode, and an Al(OTF)3 aqueous electrolyte. This battery demonstrates promising values for key performance indicators such as cycling life, reversible capacity, discharge voltage plateau, and rate capability. The present work is an important step in designing Al-ion–based batteries for practical applications. J. Am. Chem. Soc. 10.1021/jacs.0c05054 (2020).
