Room-temperature sodium-sulfur (RT Na-S) batteries are promising for low-cost and large-scale energy storage applications. However, these plagued by safety concerns due to the highly flammable nature of conventional electrolytes. Although non-flammable electrolytes eliminate risk fire, they often result in compromised battery performance poor compatibility with sodium metal anode sulfur cathode. Herein, we develop an additive tin trifluoromethanesulfonate (Sn(OTf)

Abstract Sodium‐metal batteries are the most promising low‐cost and high‐energy‐density new energy storage technology. However, sodium‐metal anode has poor reversibility, which can be optimized by constructing robust solid electrolyte interphase (SEI). Here, a concept of dual‐weak‐interaction (DWIE) is demonstrated, its double‐layer solvation structure composed weakly solvated tetrahydrofuran as inner layer, dipole interaction introduced in outer layer dibutyl ether. This dominated contact ion pairs aggregates promote to deriving inorganic‐rich SEI film, resulting smooth dendrite‐free deposition. By adjusting molecular configuration ether diisobutyl ether, further enhanced, stronger solvating effect. Thus, Na||Cu cells using DWIE achieved high Coulombic efficiency 99.22%, surpassing design strategies. Meanwhile, at 5C, Na 3 V 2 (PO 4 ) (NVP)||Na cell achieves stable cycling exceeding 3000 cycles.

Abstract Sodium‐based rechargeable batteries are some of the most promising candidates for electric energy storage with abundant sodium reserves, particularly, sodium‐based dual‐ion (SDIBs) perform advantages in high work voltage (≈5.0 V), high‐power density, and potentially low cost. However, irreversible electrolyte decomposition co‐intercalation solvent molecules at electrode interface under a charge state blocking their development. Herein, high‐salt concentration microenvironment is created proposed by tailoring solvation structures carriers including both cations anions, which maintains highly oxidation‐resistant contact ion pairs aggregates provides conductivity. The tailored structure makes great contribution to protecting graphite cathode from oxidation, co‐intercalation, structural degradation constructing robust cathode‐electrolyte interphase standout electrochemical stability. Based on this, SDIBs achieved an excellent high‐voltage cycling stability 81% capacity retention after 10 000 cycles battery showed improved rate performance 97.4 mAh g −1 maintained 100 C. It identified that regulating anion responsible stable chemistry enhanced reaction kinetics, deep insight into compatibility design between specialized electrodes.

The tightly interwoven network enhances structural reliability PEO in ether-based electrolytes resilience accommodate volume changes during cycling. Moreover, anode–electrolyte interfacial chemistry sulfur redox kinetics are ameliorated this due its strong polysulfide adsorbability multiple lithium-ion transport channels matrix quadripolymer skeleton.

Sulfurized polyacrylonitrile (SPAN) recently emerges as a promising cathode for high-energy lithium (Li) metal batteries owing to its high capacity, extended cycle life, and liberty from costly transition metals. As the capacities of both Li SPAN lead relatively small electrode weights, weight specific energy density Li/SPAN are particularly sensitive electrolyte weight, highlighting importance minimizing density. Besides, large volume changes anode require inorganic-rich interphases that can guarantee intactness protectivity throughout long cycles.
