摘要：

Structure of the layered oxide, LiNi0.8Mn0.2O2, was determined by TOF neutron powder diffraction using space group R (3) over bar m. Its ionic distribution was determined to be [Li-0.956 Ni-0.044](3a)-(Ni0.791Mn0.209)(3b)O-2. Slightly higher temperature of the synthesis caused the disordered arrangement of the Ni ions in the Li 3a sites. Nevertheless, the manganese ions introduced into the lattice were situated only at the Ni sites. The structural changes caused by the manganese substitution are clarified, and the relationship between the ionic distribution and the cathodic properties of the lithium cells is discussed.
