报告摘要

Our research focuses on a stable aqueous Zn-based battery with long cycling stability, decent energy density, and ultimate safety performance for large-scale energy storage. To achieve this purpose, we did systematic studies on the Zn metal anode, electrolytes, and new cathode development. Halogen-powered static conversion batteries (HSCBs) thrive in energy storage applications. They fall into the secondary non-flow batteries and operate by reversibly changing the chemical valence of halogens in electrodes or/and electrolytes to transfer electrons, distinguishing them from the classic rocking-chair batteries. The active halide chemicals developed so far have covered organic halides, halide salts, halogenated inorganics, and organic-inorganic halides rather than the earliest and most widely studied elemental halogens. Aside from this, various redox mechanisms have been discovered based on multi-electron transfer and effective reaction pathways, contributing to better electrochemical performances and stabilities of HSCBs. We discuss the status of halogen based conversion cathode for zinc batteries and their electrochemical mechanism-performance correlations. We first provide a detailed exposition of the fundamental redox mechanisms, thermodynamics, conversion and catalysis chemistry, and mass or electron transfer modes. We conclude with a perspective on the challenges faced by the community, and opportunities towards practical applications of high-energy halogen cathodes in aqueous zinc ion batteries.
