Key Points

The research aims to explore how lithium nitrate influences the solid electrolyte interphase in lithium-sulfur batteries depending on its concentration.
NMR spectroscopy was utilized to analyze the solid electrolyte interphase (SEI) modifications induced by varying concentrations of LiNO₃.
Concentration-dependent experiments were conducted to assess the effects on battery performance and safety.
Lithium-sulfur battery prototypes were tested for energy efficiency and cycle stability.
Higher concentrations of LiNO₃ showed significant enhancement in the stability of the SEI, improving battery life by approximately 20%.
NMR analysis revealed distinct changes in the SEI chemical composition linked to LiNO₃ concentration, leading to an improved energy density.
A marked reduction in safety hazards was noted with optimal LiNO₃ levels, indicating a safer battery operation.

Implication

Investigates lithium nitrate's impact on solid electrolyte interphase in lithium-sulfur batteries, suggesting improved performance.

Abstract
