报告摘要：
The electrochemical interface in rechargeable batteries, which acts as the critical boundary between electrode and the electrolyte, significantly influences battery performance by regulating the dynamics of charge carrier ions. Despite its importance, progress in addressing interface-related issues in batteries has been limited, primarily due to the complex nature of interface itself and difficulties in its characterization due to its nanoscale dimensions.
Our research pioneers strategies for engineering interfacial chemistry and innovating electrolytes design to effectively address interface issues. For instance, we've eliminated dendrite formation in aqueous zinc-ion batteries (AZIBs) by stabilizing the solid electrolyte interphase at the Zn/electrolyte interface. Additionally, our development of an aqueous-based soft solvating electrolyte has enabled AZIBs to achieve exceptional cycling stability and operational safety from -45 to 60℃. These advancements offer valuable insights and pave the way for superior performance in rechargeable batteries.
