From: Two-dimensional biphenylene: a promising anchoring material for lithium-sulfur batteries
Calculated charge density difference of defective BPN sheet (D1 site) adsorbed with (a) Li2S, (b) Li2S2, (c) Li2S4, (d) Li2S6, (e) Li2S8, and (f) S8. Yellow and blue regions indicate charge accumulation and charge depletion, respectively, the iso-surface is set to 0.002 e/A3. The brown, green, and yellow spheres correspond to C, Li, and S atoms, respectively.
