Abstract Designing current collectors and constructing efficient artificial solid electrolyte interphase (SEI) layers are promising strategies for achieving dendrite‐free Li deposition practical applications in metal batteries (LMBs). Electrodeposition is advantageous large‐scale production allows the direct formation of without binders, making them immediately usable as electrodes. In this study, an adherent Cu 2 S thin‐layer on foil synthesized through anodic electrodeposition from a Na solution one‐step process, followed by generation SEI via conversion reaction (3DLi S‐Cu foil). The move 3D surface to deposited surface, facilitating uniform dense deposition. 3DLi structure demonstrates stable cycling performance over 350 cycles asymmetric cell, with capacity 1 mAh cm −2 at mA . Moreover, symmetric cells 5 exhibit cycle life 1200 h. When paired commercial LiFePO 4 (LFP), full show substantially enhanced cyclability, regardless amount Li. This study provides new insights into construction SEIs applications.
