Abstract The practical application of anode‐free lithium metal batteries (AFLMBs) is impeded by poor cycling performance due to sluggish Li + transport kinetics, unfavorable side reactions, and dendrite growth. To address these issues, ≈200 nm zeolitic imidazolate framework‐8 (ZIF‐8) interphase layer introduced enable highly reversible plating/stripping electrosynthesis method. ZIF‐8 with sub‐nano windows accelerates desolvation kinetics thus suppresses reactions. Further, the internal cavities serve as an anion reservoir modulate anion‐reinforced solvation structure , facilitating formation LiF‐ 3 N‐riched solid–electrolyte interphase. Thus, Li/Cu@ZIF‐8 asymmetric cell exhibits remarkable Aurbach coulombic efficiency 99.84%, Cu@ZIF‐8/LiFePO 4 AFLMB delivers impressive capacity retention (57.8%) over 400 cycles. This work highlights effectiveness AFLMBs inspires potential porous materials interval in batteries.

Lithium metal electrodes inevitably lead to the decomposition of liquid electrolyte and lithium dendrite growth, both which result in formation unstable solid intermediates (SEIs). Gel polymer electrolytes (GPEs) are expected replace for optimizing SEI issues metal. Herein, a cellulose-based gel cross-linked by thiol-modified polyhedral oligomeric silsesquioxane (thiol-modified-POSS) was successfully obtained based on "thiol–ene" click chemistry. This organic/inorganic hybrid GPE not only exhibits high mechanical strength structural stability but also promotes generation TFSI–-rich lithium-ion solvated structures, turn accelerates uniform stable inorganic-rich SEIs. Relying SEIs between anode, Li/GPE/LiFePO4 cell capacity retention 88% after 200 cycles at 0.5 C, is much higher than GPEs without an inorganic cross-linker (only 33% retention). We anticipate that this work will provide good strategy obtain high-performance 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.
