abstract = {Anode-free lithium metal batteries (AFLMBs) have sparked
considerable attention in recent years because of their
potential for high energy density; however, they suffer from
severe Li dendrite growth and unstable solid electrolyte
interphase (SEI), which typically result in rapid capacity
decay. Herein, we demonstrate a long-life anode-free pouch
cell by designing a dual-coating protective layer
(Cu-Sn@SFPH) electrode with Sn-coated Cu (denoted as Cu-Sn)
as the bottom layer and SrF2 nanoparticles strengthened by
poly (vinylidene fluoride)-co-hexafluoropropylene (PVDF-HFP)
as the top layer. The in-situ formed LiF-rich SEI enables
fast Li+ transfer, while the lithiophilic Li-Sn and Li-Sr
alloy layers serve as nucleation seeds for uniform Li
deposition. The dual-coated Cu electrode in the
Cu-Sn@SFPH||Li cell exhibits remarkable cycling stability
for more than 3,200 h at a capacity of 2 mAh cm−2. The
NCM111||Cu-Sn@SFPH pouch cell demonstrates outstanding
performance with a capacity retention of 72.1 $\%$ and an
average Coulombic efficiency (CE) of 99.9 $\%$ for 120
cycles. Under practical conditions, with NCM cathodes and a
lean electrolyte volume, this design strategy opens a new
approach to AFLMBs.},
