Title: Materials Data on Li7Ti11O24 by Materials Project

Abstract

Li7Ti11O24 is Spinel-like structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share a cornercorner with one LiO6 octahedra and corners with eleven TiO6 octahedra. The corner-sharing octahedra tilt angles range from 56–63°. There are a spread of Li–O bond distances ranging from 1.98–2.03 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six LiO4 tetrahedra and edges with six TiO6 octahedra. There are four shorter (2.10 Å) and two longer (2.13 Å) Li–O bond lengths. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share a cornercorner with one LiO6 octahedra and corners with eleven TiO6 octahedra. The corner-sharing octahedra tilt angles range from 55–63°. There are a spread of Li–O bond distances ranging from 1.99–2.03 Å. There are five inequivalent Ti+3.73+ sites. In the first Ti+3.73+ site, Ti+3.73+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent LiO4 tetrahedra and edges with six TiO6more » octahedra. There are a spread of Ti–O bond distances ranging from 2.00–2.02 Å. In the second Ti+3.73+ site, Ti+3.73+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six LiO4 tetrahedra, an edgeedge with one LiO6 octahedra, and edges with five TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.87–2.11 Å. In the third Ti+3.73+ site, Ti+3.73+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six LiO4 tetrahedra, edges with two equivalent LiO6 octahedra, and edges with four equivalent TiO6 octahedra. There is four shorter (1.98 Å) and two longer (2.01 Å) Ti–O bond length. In the fourth Ti+3.73+ site, Ti+3.73+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six LiO4 tetrahedra and edges with six TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.99–2.02 Å. In the fifth Ti+3.73+ site, Ti+3.73+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six LiO4 tetrahedra and edges with six TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.98–2.03 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded to one Li1+ and three Ti+3.73+ atoms to form a mixture of distorted corner and edge-sharing OLiTi3 trigonal pyramids. In the second O2- site, O2- is bonded to one Li1+ and three Ti+3.73+ atoms to form a mixture of distorted corner and edge-sharing OLiTi3 tetrahedra. In the third O2- site, O2- is bonded to one Li1+ and three Ti+3.73+ atoms to form a mixture of distorted corner and edge-sharing OLiTi3 tetrahedra. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Li1+ and two equivalent Ti+3.73+ atoms. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+ and three Ti+3.73+ atoms. In the sixth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Li1+ and two Ti+3.73+ atoms. In the seventh O2- site, O2- is bonded to one Li1+ and three Ti+3.73+ atoms to form a mixture of distorted corner and edge-sharing OLiTi3 tetrahedra.« less
