Abstract: | A series of layered-type pseudo four-component Li-Ni-Co-Ti oxides were prepared to explore optimal cathode materials for a lithium-ion secondary battery. The new layered-type compounds were prepared using a combinatorial material-preparation system based on electrostatic spray deposition (the “M-ist Combi” system), and combinatorial powder X-ray diffraction. The composition region of the new compounds (Liα(NixCoyTiz)O2 (α∼1, 0 ≤ x ≤ 1, 0 ≤ y ≤ 1, z∼0.2, x + y + z = 1.0)) was found to be wider than the composition region previously reported (LiNi0.8−yCo0.2TiyO2 (0 ≤ y ≤ 0.1)). |
