A Dual-Additive Strategy Constructing Robust Li 3 N-Rich SEI and Proton Scavenging for High-Rate Lithium Metal Batteries

Key Points

• To develop a robust Li3N-rich solid electrolyte interphase (SEI) for high-rate lithium metal batteries.
• Combination of 3-cyano-1,2,4-triazole and 1-(Trimethylsilyl)imidazole
• Investigation of π-donoracceptor interactions
• Assessment of mechanical strength and ionic conductivity of SEI.
• Formation of a Li3N-rich SEI with enhanced mechanical strength.
• Improvement in ionic conductivity compared to standard SEIs.
