Lithium-metal batteries (LMBs) incorporating nickel-rich cathodes have the potential to achieve superior energy densities. However, challenges associated with electrolyte-electrode interphases (EEIs) impeded successful transition of these advanced systems into practical applications. In this study, azidotrimethylsilane (ATMS) is introduced as a multifunctional additive for traditional carbonate-based electrolytes. The azido group in ATMS plays dual role electrochemical reactions, multiple nitrogen (N) atoms engaging both nucleophilic and electrophilic interactions. These N tend undergo preferential oxidation reactions at cathode, forming stable cathode electrolyte interphase, while also undergoing reduction anode inhibit lithium dendrite growth. Si-N bond structure has unique reactivity, effectively neutralizing HF produced from LiPF6 decomposition, thus preventing recurrent formation EEIs battery. As result, long-cycle performance Li||NCM811 significantly improved, capacity retention increasing 34.7% baseline 82.6% after 600 cycles. Similarly, enhances cycling Li||Li symmetric cells, extending their lifespan over 800 h, improves Coulombic efficiency Li||Cu cells 81.6 91.6%. synergistic effect on anodes further high-voltage LMBs.

Abstract The unstable interface between reactive anodes and electrolytes in batteries has been identified as a critical factor limiting the long‐cycle stability of batteries. An effective solution is to build solid electrolyte interphase (SEI) that acts passivation layer mitigate side reactions electrolytes. mechanical SEI important because with poor cannot survive volume topography fluctuation anode upon cycling. stress built‐up would cause failure SEI, resulting exposure fresh surface electrolyte, consuming limited active materials electrolytes, inducing rapid battery decay. Therefore, understanding regulating imperative for improving cycle life. In this review, properties are discussed. Then, advanced characterization tools measure introduced. Additionally, recent progress on presented terms situ ex modifications SEI. Finally, an insightful outlook provided further understand regulate performance.

Lithium (Li) dendrite is one of the most fatal obstacles for developing practical high energy Li metal batteries, while alloy substrates, with strong lithiophilicity, have attracted increasing interest directing uniform deposition. However, previous research studies associated inhibition closely adsorption energy. Yet, deposition process not solely about an isolated atom, where a comprehensive understanding interfacial lattice mismatch and atom diffusion should also be taken into account. Here, we explore behavior from adhesion work, representing stability bonding strength, both diffusion. It found that overpotential inversely related to requires low barrier. These detailed relationships may offer guidance subsequent substrate development.
