Pressure significantly influences lithium (Li) deposition behavior. Although previous studies investigating the influence of pressure on Li have often overlooked impact mechanical spacer within cell, this work specifically focuses detail. In study, we explored effects electrochemical properties, morphology, solid–electrolyte interphase (SEI), and thermal stability metal deposition, using as a variable in small-sized electrode half-cell. The experimental results demonstrate that higher positively enhances performance across multiple metrics. However, beneficial decrease with increasing capacity. Specifically, at low capacity (1 mAh/cm2), facilitates by promoting SEI stabilization, enabling easier reducing impedance, enhancing stability. Conversely, high (4 does not improve aforementioned properties. This study combines morphology deposited assessments, providing valuable research methods for evaluating external deposition.

Abstract The thickness and composition of the solid electrolyte interphase (SEI) on lithium (Li) metal are critical factors influencing dendrite growth. This study introduces a novel selection strategy based electrochemical corrosion principles. By employing LiCl LiNO 3 simultaneously, itself has high donor number, low desolvation energy, Li⁺ transference number conductivity, moderate stability window. In addition, it dynamically reduces SEI reactivates dead Li, forming ≈100 nm enriched with LiF Li 2 O anode, which ensures stable cycling symmetric cells for 2000 h at current density 5 mA cm⁻ . Consequently, using LiFePO 4 (LFP) as cathode ‐LiCl‐added exhibit excellent performance 1600 cycles 680 g⁻ 1 Even thin (5 µm)|LFP cell retains 95% capacity after 70 170 universality feasibility this design also validated in diverse battery chemistries such anode‐free Cu|LFP, Li|LiNi 0.8 Mn 0.1 Co (NMC811), Li|S cells, well pouch high‐loading LFP NMC811 cathodes, showcasing promising batteries.
