Overview

This research demonstrates an innovative hybrid SEI using Li3N and LiF to improve dendritic growth and cycling stability.

Key Points

  • The engineered hybrid interphase allows lithium plating at a stable rate, enhancing cycling stability significantly.
  • Cycles achieved stable lithium metal anodes for over 8000 hours, maintaining ≈93.1% capacity after 1000 cycles.
  • A novel two-step process combines metallurgical pre-seeding with electrochemical formation for optimal ion transport.
  • This advancement enables long-life lithium metal batteries, potentially impacting large-scale energy storage applications.
