Exploring stability challenges in next-generation batteries? This review delves into the behavior of NO3−-based electrolyte additives in lithium metal batteries, addressing key issues such as dendrite formation and short cycle life. The study focuses on how these additives can stabilize the solid electrolyte interface (SEI) layer, promising enhanced stability and performance for lithium metal batteries. The NO3− anion in the N-based electrolyte additive promotes the formation of compounds like Li3N and Li2O in the SEI layer on the lithium metal surface, facilitating Li+ ion conduction and increasing mechanical strength. Addressing challenges related to the solubility of N-based electrolyte additives in carbonate-based electrolytes, the review proposes practical strategies for their incorporation, overcoming limitations associated with ether-based electrolytes. Ultimately, this research offers valuable insights into the practical application and development of N-based electrolyte additives, paving the way for more stable and efficient lithium metal batteries. By addressing the challenges of solubility and oxidative stability, the review contributes to the ongoing efforts to commercialize lithium metal batteries for next-generation energy storage.
