title: Charge-discharge properties of a layered-type Li(Ni,Co,Ti)O2powder library.
abstract: A powder library of layered Li(Ni,Co,Ti)O2(Ni ≤ 0.8, Ti ≤ 0.2) compounds was prepared by electrostatic spray deposition. From powder x-ray diffraction patterns, most of the powder library sintered at 700○C was indexed as a single phase belonging to the space groupR[Formula: see text]m. These results were almost identical to those obtained from a study by combinatorial exploration. We investigated the charge-discharge characteristics of the Li(Ni,Co,Ti)O2powder library in a voltage range from 4.2 to 2.8 V at 1 C and found favorable cycling properties in the LiNixCo0.9-xTi0.1O2(0 ≤x≤ 0.6) compounds.
