Abstract ：
Sodium metal as the anodes for sodium metal batteries (SMBs) possess several advantages, including high theoretical capacity, high abundance and low-cost, which make SMBs formidable contenders for constructing alternative batteries to lithium-based ones. However, the presence of an undesirable solid electrolyte interface (SEI) between Na metal and liquid electrolyte can result in sluggish Na ion transfer kinetics, substantial consumption of electrolyte, and dendrite growth issues, particularly at ultra-low temperatures. To address these challenges, a three-dimensional (3D) artificial protection layer composed of Na3Bi and NaF (NBF) on the Na anode surface is successfully fabricated through a simple in-situ reaction. Both theoretical and experimental findings demonstrate that this artificial protection layer exhibits strong sodiophilicity, enhanced ionic conductivity, excellent and electronic insulation property, which can effectively suppress the continuous electrolyte decomposition. As a result, at low operating temperatures (-30 degrees C), such an NBF symmetric cell achieves a long cycle life of over 1400 h (0.1 mA cm-2@ 0.1 mAh cm-2). And the electrochemical performance of NBF is exceptional when it is utilized as the anodes in symmetric cells, demonstrating a cycle-life exceeding 2390 h at 0.5 mA cm-2@0.5 mAh cm-2, and also in sodium metal full cells at 5C, exhibiting over 2000 cycles. Therefore, the results provide support for the possibility of utilizing the artificial protection layer in developing a safeguarding coating for sodium metal anodes.

Abstract ：
The application of zinc-metal-based batteries is hindered by the low thermodynamic stability of zinc anodes and the sluggish desolvation kinetics of the interfacial [Zn(H2O)6]2+ complex, which can induce serious side reactions and exacerbate dendrite formation. Herein, an innovative catalytic desolvation mechanism is proposed to manipulate the interfacial solvation structure by engineering a pi-electron-rich (C 00000000 00000000 00000000 00000000 11111111 00000000 11111111 00000000 00000000 00000000 O/CN configurations) covalent organic polymer (COP) layer as an interfacial catalyst. It was revealed that the pi-electrons can trigger dissociation of the [Zn(H2O)6]2+ complex through an ortho-synergistic reaction process, which includes a nucleophilic reaction between electron-accepting C atoms at CO/CN sites and H2O molecules and an electrophilic reaction between electron-donating sites near O and N heteroatoms and Zn2+. In situ characterization analysis combined with advanced theoretical calculations confirmed that such a catalytic desolvation process can dynamically induce contact ion pairs and aggregate dominated interfacial solvation structures, boosting Zn2+ diffusion and deposition kinetics. Consequently, suppressed side reactions and homogenous (002)-crystal-preferred Zn2+ deposition can be simultaneously achieved. Therefore, an excellent cycling lifespan of 2500 h was obtained for the symmetric Zn cell and an ultra-stable cycling lifespan of 28 000 cycles for full cells. We believe that this catalytic desolvation strategy will pave a new avenue in the interfacial design of Zn anodes.

Abstract ：
The Liquid Antimony Anode-based Solid Oxide Fuel Cell (LAA-SOFC) represents a promising energy conversion approach for generating power using complex fuels. This study addresses the relationship between the liquid- -liquid distribution of Sb-Sb2O3 2 O 3 and the corresponding electrochemical performance of LAA-SOFC. A 2-D axisymmetric model that incorporates the two-phase flow of Sb-Sb2O3, 2 O 3 , alongside the electric field and the chemical/electrochemical reactions is successfully developed to explore the reaction and convection characteristics of LAA in LAA-SOFC under gravitational influence. The model results indicate that the density disparity between Sb and Sb2O3 2 O 3 can drive convection and stratification with Sb2O3 2 O 3 generation fostering continuous convection within the anode. The high Peclet number suggests that the convection is the primary transport mechanism in the anode. The limited Sb2O3 2 O 3 reduction results in its accumulation in the upper layer, diminishing the effective reaction area and leading to a rapid decline in discharge voltage. However, the ionic conductivity of Sb2O3 2 O 3 at the Sb/Sb2O3 2 O 3 interface can facilitate approximately 10-20% of the reactions, marginally mitigating the increase in voltage loss. To offset Sb2O3 2 O 3 accumulation's impact on the electrochemical reactions, a horizontal tubular LAA-SOFC is designed and constructed, which can effectively sustain the discharge voltage across a broad Sb2O3 2 O 3 fraction range of 0-85%.
