报告摘要：
Multivalent-metal anodes, such as aluminum, zinc, magnesium, and calcium, are very attractive owing to their high theoretical capacity, natural abundance, and high safety. However, electrochemical performance and stability of multivalent-metal anodes are also deteriorated due to Zn dendrite formation, corrosion, and hydrogen evolution reaction in aqueous electrolytes. In this talk, I will introduce our recent progress on the electrolyte additives, polymeric electrolytes, and the associated interfacial engineering for reversible Zn metal anodes. Firstly, I will address the design guideline of electrolyte formulation that can modulate solvation structures, interfacial chemistry, and EDL structures. Secondly, a new concept of electrolyte additives including localized high concentration electrolytes through a molecular engineering and bioinspired isomeric additives will be introduced. Finally, mechanically strong and tough ionic liquid gel electrolyte for energy-dense four-electron Zn-I2 full batteries will be introduced.
