Lithium metal batteries are the most promising next‐generation energy storage technologies due to their high density. However, practical application is impeded by serious interfacial side reactions and uncontrolled dendrite growth of lithium anode. Herein, copper 2,4,5‐trifluorophenylacetate designed explored stabilize anode in‐situ constructing a dense mixed‐conductive protective layer. The formed passivated layer not only significantly inhibits avoiding direct contact between electrolyte but also effectively suppresses unique inorganic‐rich compositions properties. As result, 2,4,5‐trifluorophenylacetate‐treated anodes show greatly improved cycle stability under both current density areal deposition capacity. Notably, assembled liquid symmetrical cells with can stably work for more than 3000, 5000, 4800 h at 1.0 mA cm −2 –1.0 mAh , 2.0 –5.0 10 respectively. Furthermore, full cell LiFePO 4 loading (~16.9 mg ) shows enhanced life 250 cycles stable Coulombic efficiencies (>99.1%). Moreover, all‐solid‐state battery LiNi 0.6 Co 0.2 Mn O 2 (~5.0 exhibits stability. These findings underline that great promise high‐performance batteries.

Abstract Lithium dendrite growth and the resulting safety concerns hinder application of lithium metal. Compared with single metal or medium entropy alloys, high‐entropy alloys (HEAs) are a promising solution to solve challenges anodes due their unique properties. However, designing HEA layer appropriate elements proportion has become obstacles. Herein, machine learning (ML), density functional theories (DFT) calculation data analysis reveal contribution Zn in lithiophilicity, Al hardness Fe, Co, Ni providing magnetism. The magnetron sputtering is used construct interphase layer, three parameters (sputtering power, time, substrate rotation speed) optimized via particle swarm optimization (PSO) based on logarithm average coulombic efficiency (CE) Li||Cu half cells. While high strength, compactness, flatness constructed, Li||Li symmetric cell assembled by HEA@Li at 1 mA cm −2 , mAh can cycle stably for 2400 h, discharge capacity retention rate Li||LFP >90% after 300 cycles C CE 99.67%. Design assisted ML provides path potential batteries.

Lithium (Li) metal has received significant attention as an anode material for next-generation batteries due to its high theoretical capacity and low redox potential. However, the reactivity of Li leads formation a native layer on surface, inducing nonuniform Li+ flux at electrolyte/Li interface, which promotes growth dendrites. In this study, perfluorooctyltriethoxysilane (PFOTES) was vaporized chemically react with modify surface. This gas-solid reaction removes while simultaneously forming homogeneous solid electrolyte interphase (SEI) layer. The Si-O-Si network formed through condensation reactions between PFOTES molecules, combined fluorinated carbon chain PFOTES, facilitates rapid kinetics metal/electrolyte interface. Consequently, exchange current density PFOTES-modified (PFOTES-Li) increased 0.2419 mA cm-2, is 20 times higher than that Bare-Li (0.0119 cm-2). SEI derived from effectively mitigates pulverization dead during long-term cycling. As result, PFOTES-Li||LiNi0.8Mn0.1Co0.1O2 full cell exhibits excellent discharge 203.4 mAh g-1 under areal loading 4.2 cm-2. study demonstrates strategy removing surface stable layer, thereby ensuring conductivity mechanical stability, thus improving cycling stability batteries.
