Popis
Shrnutí:Rechargeable aqueous batteries based on metallic anodes hold tremendous potential of high energy density enabled by the combination of relatively low working potential and large capacity while retaining the intrinsic safety nature and economical value of aqueous systems; However, the realization of these promised advantages relies on the identification of an ideal metal anode chemistry with all these merits. In this review, the emerging Sn metal anode chemistry is examined as such an anode candidate in both acidic and alkaline media, where the inertness of Sn toward hydrogen evolution, flat low voltage profile, and low polarization make it a unique metal anode for aqueous batteries. From a panoramic viewpoint, the key challenges and detrimental issues of Sn metal batteries are discussed, including dead Sn formation, self‐discharge, and electrolyte degradation, as well as strategies for mitigating these issues by constructing robust Sn anodes. New design approaches for more durable and reliable Sn metal batteries are also discussed, with the aim of fully realizing the potential of Sn anode chemistry. Rechargeable aqueous batteries with metal anodes promise enhanced energy density, combining higher output voltage and capacity with high safety. This perspective highlights the emerging potential of the Sn metal anode, emphasizing its resistance to hydrogen evolution, high reversibility, and sustainability. Key challenges, including dead Sn formation and electrolyte evolution, as well as innovative design strategies for robust Sn‐based batteries are also discussed. The development of Sn metal batteries could contribute to a sustainable society.
