Coarser grains are more prone to serious electrode damage during their lithiation. In article number 1902150, Sa Li, Yunhui Huang, Ju Li and co‐workers report that grain refinement by alloying can improve lithiation/delithiation ductility and reduce Sn foil damage by denser grain boundary sliding systems. A 50 µm self‐standing Li x 3Ag0.5Cu96.5Sn foil anode, prepared by mechanical prelithiation, achieves good mechanical strength and demonstrates a striking full‐cell cycling performance.
