Figure 2: Comparison of crystal structures between LiOOH·H2O and LiOH·H2O.
From: Proton enhanced dynamic battery chemistry for aprotic lithium–oxygen batteries

Crystal structure of LiOOH·H2O as derived from (a) Rietveld refinement of synchrotron X-ray powder data and (b) from DFT refinement. (c) The crystal structure of LiOH·H2O given by Hermannson et al.44 Here the primitive cell is shown to emphasize the close relation between the structures of both phases. (O: red; H: grey, Li: magenta). Broken lines indicate the hydrogen bonds stabilizing the structures.
