“…Recently, based on the research hotspots of lithium metal challenges, electrolyte modification, [ 13 , 14 , 15 ] SEI stabilization design, [ 16 , 17 , 18 , 19 , 20 ] solid electrolyte engineering, [ 21 , 22 , 23 ] three‐dimensional (3D) structured Li electrodes, [ 24 , 25 , 26 , 27 ] lithiophilic nucleation seeds, [ 26 , 28 ] high‐strength separators, [ 29 , 30 , 31 ] etc., are extensively demonstrated. But among them, the Li‐phase evolution at the nanoscale during the nucleation and growth has been rarely reported.…”
