Abstract

The layered oxide compounds xLi₂MnO₃·(1 - x)LiMO₂ (M=Ni, Mn, Co) are of great interest as positive electrode materials for high energy density lithium-ion batteries. In-situ neutron diffraction was carried out to compare the structural changes between the classical layered compound Li[Ni_1/3Mn_1/3Co_1/3]O₂ (x=0) and lithium-excess layered compound Li[Li_0.2Ni_0.18Mn_0.53Co_0.1]O₂ (x=0.5) during electrochemical cycling. In this work, lab made pouch cells were built for the in-situ study and graphite was used as the anode material. Irreversible structural change of Li[Li_0.2Ni_0.18Mn_0.53Co_0.1]O₂ during first charge (4.7 V)/discharge cycle (2.0 V) was indicated by dynamic changes in lattice d-spacing, while the Li[Ni_1/3Mn_1/3Co_1/3]O₂ showed completely reversible structural evolution between 4.4 V and 2.5 V. Ex-situ neutron powder diffraction was performed on both pristine and chemically delithiated lithium-excess layered compounds to better understand the irreversible structure change.
