Figure 16. Illustration of lithium metal deposition on Br-doped graphene host. (A) Li+ flow is homogeneous above Br-doped graphene-like sheet and CuBr; (B) CuBr was converted into LiBr after Li plating. The selective and targeted deposition of lithium metal on Br-doping sites, as well as the surrounding LiBr, govern lithium metal nucleation into Li seeds with a pancake-like shape. Gray, blue, red, and orange denote C, Br, Cu, and Li, respectively; (C) The nucleation and development of lithium metal on modified carbon host. Reproduced with permission[94].
