| 英文摘要 | Uneven nucleation and fragile solid electrolyte interphase (SEI) restrict the practical application of lithium (Li) metal anode. A versatile strategy to simultaneously overcome these two drawbacks is critical for Li metal batteries (LMBs). Herein we propose an "aggressive aluminum (Al) pulverization" strategy to form abundant artificial nucleation sites and robust SEI films adjacently, leading to homogeneous Li deposition/stripping and high Li Coulombic efficiency. A core-shell structure with Al core and alumina-silica (Al2O3-SiO2) shell, Al@Al2O3-SiO2 (AAS), could be easily synthesized, by modulating the chemical diffusion of silicon (Si) element towards Si-Al alloy surface. The active SiO2 sites not only contribute to form the robust SEI layer, but also facility the lithiation of the AAS, accelerating the conversion of reversible Li-Al alloy into inert Li3Al2 phase. The as generated AAS with Li3Al2 and Li12Si7 phases possess negligible Li nucleation over-potential (similar to 0.7 mV), serving as an optimal structure for dendrite-free Li plating/stripping with a prolonged life-span of 6 times longer than that of the unprotected counterpart in carbonate electrolytes. |
