dc.description.abstract | Anode-free lithium (Li) batteries that function via direct Li plating/stripping on metal current collectors have garnered significant interest in the field of metallic Li as an ideal negative electrode. However, dendritic Li growth creates unoccupied space in the battery, diminishing volumetric energy density. Our research reveals that Li adatoms can reposition on metal substrates via surface migration by interacting with individual grains at the atomic level after electro-adsorption of Li ions. By examining Li morphologies on diverse types of substrates, we find that the near-zero migration barrier of Li adatoms, especially on single crystal Cu(111) foils, is a key parameter that inhibits Li dendrites by initiating horizontal growth in an isotropically faceted nucleation shape, with 80% capacity retention even after 120 cycles (versus 29 cycles for polycrystalline Cu), paired with LiNi0.8Co0.1Mn0.1O2 (NCM811) cathodes with a high-loading level (5.3 mA h cm-2). Based on our findings, we highlight the importance of metal substrates that promote favorable surface dynamics of Li adatoms. Single-crystal Cu(111) foil promotes the lateral growth of lithium rhombic dodecahedra, preventing dendritic lithium growth during plating. This is achieved through surface migration and the interaction of lithium adatoms with individual grains. | - |
