LiCoO2 has rhombohedral symmetry and belongs to the space group R-3m, This crystal structure of closed-packed oxygen layers stacked in an ABC arrangement with Co and Li ions residing in octahedral sites in alternating layers between the oxygen planes. Layers of intercalated lithium and cobalt(III) ions are present in Figure 2a. In order to create the Co-O layers, the cobalt(III) ion forms a stable connection with the nearby oxygen anion at the octahedral sites Figure 2b. At the end, the CoO2 plans are intercalated between the lithium layers. Lithium and cobalt(III) ions alternately occupy the octahedral positions of these layers, forming an ABCABC-type sequential stacking with oxygen ion layers as shown in Figure 2c
