摘要 | The large-scale implementation of lithium metal batteries (LMBs) has long been plagued by the uncontrollable Li deposition triggered safety issues. Herein, a lithiophilic three-dimensional Li anode scaffold, which is prepared by molten Li infusion aided by confined growth of low-cost Zn clusters, is rationally constructed for high-performance LMBs. Owing to the synergy of the carbon host and the effective regulation from the Zn nanoclusters, the large volumetric change of Li metal is well mitigated and shows a smooth and dendrite-free behavior. The Li anode scaffold can deliver much improved Coulombic efficiency, superior rate performance, and long cycle lifespan with much lower voltage polarization. Furthermore, the half cells of Li anode scaffold paired with LiFePO4/LiCoO2/sulfur can achieve a higher specific capacity and longer stable cycling life than those with conventional Li foil. The Li|LFP cells can achieve a stable cycling over 250 cycles at 1C with a higher capacity retention of approximate to 90.8%, and a higher initial discharge capacity of 924.6 mAh g(-1) with a high capacity retention over 300 cycles can also be obtained in Li|S cells at 1C. This work demonstrates a cost-effective and scalable strategy for stable Li metal anode toward next-generation and high-performance LMBs. |
