Zusammenfassung:•An ultrathin (∼35 μm) lithium metal anode was fabricated.•(822)-texture of Li22Sn5 engenders dense Li+ deposition along Li-(110) facet.•Stable plating-stripping cycling in carbonate electrolyte was achieved under 80% DOD.•>2.5 mAh/cm2 full pouch cells with N:P = 2.1 delivers good cycle performance. A thin Li metal anode is imperative for practical lithium metal batteries (LMBs). Fabricating and stabilizing
