Structural Relaxation of Li(x)(Ni(0.874)Co(0.090)Al(0.036))O(2) after Lithium Extraction down to x = 0.12

A structural relaxation study has been carried out on Li(x)(Ni(0.874)Co(0.090)Al(0.036))O(2) after the electrochemical lithium was extraction down to x = 0.12. These relaxation analyses have been carried out using X-ray diffraction coupled with the Rietveld analysis, assuming two phases (H2 and H3)...

Sumario:A structural relaxation study has been carried out on Li(x)(Ni(0.874)Co(0.090)Al(0.036))O(2) after the electrochemical lithium was extraction down to x = 0.12. These relaxation analyses have been carried out using X-ray diffraction coupled with the Rietveld analysis, assuming two phases (H2 and H3) and co-existence with [Formula: see text] symmetry. The mole fraction of the H3 phase seemed not to vary largely during the relaxation time. As for the lattice constants, both H2 and H3 phases gradually increased the a-axis with the relaxation time. On the other hand, H2 and H3 phases increased and decreased the c-axis, respectively. The results are compared with that of previously reported Ni-rich NCA.
