Materials Data on Li(CoO2)2 by Materials Project
Abstract
Li(CoO2)2 is Spinel-like structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with twelve CoO6 octahedra. The corner-sharing octahedra tilt angles range from 59–62°. There are a spread of Li–O bond distances ranging from 1.91–2.03 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with six CoO6 octahedra and edges with three CoO6 octahedra. The corner-sharing octahedra tilt angles range from 61–66°. There are a spread of Li–O bond distances ranging from 1.78–1.93 Å. There are four inequivalent Co+3.50+ sites. In the first Co+3.50+ site, Co+3.50+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent CoO6 octahedra, corners with three equivalent LiO4 tetrahedra, a cornercorner with one LiO4 trigonal pyramid, edges with five CoO6 octahedra, and an edgeedge with one LiO4 trigonal pyramid. The corner-sharing octahedral tilt angles are 50°. There are a spread of Co–O bond distances ranging from 1.89–1.91 Å. In the second Co+3.50+ site, Co+3.50+ is bonded tomore »
