Abstract

The layered T#2-Li_2/3Co_2/3Mn_1/3O₂ phase was obtained by ion exchange in molten salts of Na⁺ by Li⁺ in P2-Na_2/3Co_2/3Mn_1/3O₂. X-ray photoelectron spectroscopy (XPS) analyses have shown that cobalt and manganese ions are present in T#2-Li_2/3Co_2/3Mn_1/3O₂ at the trivalent and tetravalent oxidation states, respectively. The refinement of the neutron diffraction data was achieved, and the structure was described in the Cmca space group with two Co_2/3Mn_1/3O₂ slabs per unit cell. Thanks to nuclear density Fourier difference maps calculations, it was shown that the lithium ions are distributed in the 8e and 8f_edges tetrahedral sites. Transmission electron microscopy has shown no evidence of lithium ordering in the interslab space.

 tetrahedral sites. Transmission electron microscopy has shown no evidence of lithium ordering in the interslab space.</s0>
