ABSTRACT The solvent‐rich solvent sheath in low‐concentration electrolytes (LCEs) not only results high desolvation energy of Li + , but also forms organic‐rich solid electrolyte interface film (SEI) with poor conductivity, which hinders transport at the electrode‐electrolyte and greatly limits application LCEs. Here, electrochemical performance LCEs is enhanced by dual interfacial modification LiNO 3 vinylene carbonate (VC) additives. Results show that preferentially reduced about 1.65 V to form an inorganic‐rich incomplete SEI inner layer. formation N LiN x O y inorganic components helps achieve rapid film, bare electrode surface caused layer provides a place for subsequent decomposition VC. Then, lower potential 0.73 V, VC generate poly(VC)‐rich outer layer, lithium‐philic sites weakens interaction between ethylene (EC). modulates solvation structure reduces . This ingenious design bilayer enhances inhibits traditional solvents swelling graphite. As result, battery using 0.5 M LiPF 6 EC/diethyl (DEC) 0.012 vt% improved higher level than one 1.0 EC/DEC electrolyte. research expands strategy promising applications constructing favorable enhance interface.

Abstract Sodium metal batteries (SMBs) with the advantages of high energy density and low cost have attracted extensive attention as next‐generation rechargeable battery technology. However, SMBs suffer from severe Na dendrite undesired solid electrolyte interface (SEI) layer, which inevitably destroy cycling durability safety. Herein, a p‐π conjugated organic molecule (OHTAPQ) redox‐active carbonyls pyrazines is employed robust artificial SEI layer on anode (denoted OHTAPQ@Na) to address these issues. The unique chelation N O + ions in an OHTAPQ‐based facilitates good adsorption capacity diffusion barries for uniform deposition behavior. As result, OHTAPQ@Na||OHTAPQ@Na symmetric cell shows long‐term cycle lifespan (over 1500 h at 2 mA cm −2 ), OHTAPQ@Na||Na 3 V (PO 4 ) cells deliver retention 82% after 1600 cycles. This research provides handy way protection functional organics SMBs.

Solid-state lithium metal batteries (SSLMBs) suffer from stress accumulation, poor interfacial stability, and dendrite growth. A potential solution to these issues is the design of a three-dimensional nanotubular mixed ionic-electronic conductor (MIEC) as host, which induces plating/stripping inside via Coble creep. Herein, we develop novel MIEC comprising mechanically robust electrochemically stable titanium nitride (TiN) nanotube array, with an ion-conductive solid electrolyte interphase (SEI) coating on inner surface TiN host. The highly lithiophilic provides consecutive ion/electron transport channels, promoting uniform deposition nanotubes thereby maintaining exceptional stability during cycling. Consequently, SSLMBs employing this rationally designed host demonstrate remarkable electrochemical performance. This work new insights for construction advanced MIECs high-performance SSLMBs.
