The high reactivity of lithium metal leads to the uncontrolled growth dendrites during charging and discharging process batteries, which results in poor cycle performance batteries. In this paper, we innovatively utilized 1, 3-propanediol cyclic sulfate (PCS) as an additive successfully construct a smooth dense SEI layer containing sulfur element on anode surface. Under action PCS, cells show excellent performance. After 200 cycles, with baseline electrolyte (BE) + 1 wt.% PCS still has capacity 148mAh g−1 81.38% retention compared BE. In-situ optical microscopy is pioneeringly applied showcase generation showed that participated formation layer, indicating optimized better conductivity Li+ chemical stability, thus inhibiting malignant deposition decomposition above anode.

Abstract Sodium metal is regarded as one of the most promising anode materials due to its high theoretical capacity (1166 mAh g −1 ) and low redox potential (−2.714 V vs standard hydrogen electrode). However, practical application sodium hindered by formation dendrites during Na stripping plating, which can degrade performance cause safety hazards. To address this issue, previous work focuses on leveraging either 3D current collectors or liquid modification collectors. In work, both strategies are simultaneously leveraged design a Cu foam with (LM@Cu) for dendrite‐free plating. The configuration effectively reduces local density evenly distributes electric fields, while introduction enhances sodiophilicity lower nucleation barrier sodium, thereby promoting uniform As result, symmetric cells LM@Cu maintain stable cycling over 2800 h. Additionally, full comprising Na‐LM@Cu 3 2 (PO 4 sustain 97.5% upon 1000 cycles, underscoring great potentiality metal‐mediated in energy storage.

Abstract Sodium metal batteries, known for their high theoretical specific capacity, abundant reserves, and promising low‐temperature performance, have garnered significant attention. However, the large ionic radius of Na + sluggish transport kinetics across interfacial structure hinder practical application. Previous reviews rarely regulated electrolyte performance from perspective anions, as important components electrolyte, regulation mechanism is not well understood. Herein, a novel anion receptor additive, 4‐aminophenylboronic acid pinacol ester (ABAPE), proposed to weaken coupling between anions cations accelerate kinetics. The results calculations X‐ray photoelectron spectroscopy with deep Ar‐ion etching demonstrate that introduction this additive alters solvation , reduces desolvation barrier forms stable dense electrode‐electrolyte interface. Moreover, ABAPE hydrogen bonds (−NH ⋅ O/F) H 2 O/HF, effectively preventing hydrolysis NaPF 6 stabilizing acidic species. Consequently, Na||Na symmetric cell exhibits excellent long‐cycle 500 h at 1 mA cm −2 0.5 mAh . 3 V (PO 4 ) (NVP) addition maintains capacity retention 84.29 % C after 1200 cycles presents no decay over 150 −40 °C.
