Progressive chemical .delithiation of commercially available lithium cobalt oxide () showed consecutive changes in the crystal properties. Rietveld refinement of high resolution X-ray and neutron diffraction revealed an increased lattice parameter c and a reduced lattice parameter a for chemically delithiated samples. Using electron microscopy we have also followed the changes in the texture of the samples towards what we have found is a critical layer stoichiometry of about with x=1/3 that causes the grains to exfoliate. The pattern of etches by delithiation suggests that unrelieved strain fields may produce chemical activity. The effect of chemical dedoping of leads to a significant change in the (003) peak and to exfoliation for x=1/3. Chemical delithiation of showed consecutive changes in crystal properties. We performed X-ray as well as neutron diffraction on delithiated material. Crystal analysis revealed an increased c and a reduced a for delithiated samples. Electron microscopy revealed changes in the texture for (x=1/3).
