Lithium‑Ion Dynamic Interface Engineering of Nano‑Charged Composite Polymer Electrolytes for Solid‑State Lithium‑Metal Batteries

Caption

  • The surface charge characteristics of halloysite nanotubes (HNTs) are manipulated to engineer the Li+-dynamic interface (Li+-DI) in composite polymer electrolytes.
  • Surface charge characteristics of HNTs generate pronounced impact on not only the ionic/mechanical properties of the composite electrolytes, but also the formation and composition of solid–electrolyte interphase (SEI) layer.
  • HNTs+-supported Li+-DI exhibits an anion-rich Li+-solvation structure and soft-and-tough mechanical interface, leading to LiF-rich SEI layer and improvement of toughness by over 2000% compared with the control.
