Abstract

A synchrotron based in situ XRD technique was used to investigate the structural changes of Li_1-xCo_1/3Ni_1/3Mn_1/3O₂ as cathode material in lithium battery during first charge in comparison with Li_1-xNi_0.8Co_0.15Al_0.05O₂. The structural changes of these two cathode materials during first charge follow the similar trend as LiNiO₂: an expansion along the c-axis of the unit cell with contractions along the a- and b-axis during the early stage of charge and a major contraction along the c-axis with slight expansions along the a- and b-axis near the end of charge at high voltage limit. However, the degree of disorder in Li_1-xCo_1/3Ni_1/3Mn_1/3O₂ is higher than in Li_1-xNi_0.8Co_0.15Al_0.05O₂, which in turn is higher than in LiNiO₂. More importantly, the structural stability of Li_1-xCo_1/3Ni_1/3Mn_1/3O₂ is higher than Li_1-xNi_0.8Co_0.15Al_0.05O₂, which in turn is higher than LiNiO₂, as reflected in the suppression of hexagonal 3 (H3) phase with collapsed c-axis formed at the end of charge.
