摘要：
A powder library of layered Li(Ni,Co,Ti)O-2 (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 degrees C was indexed as a single phase belonging to the space group R (3) over barm 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)O-2 powder library in a voltage range from 4.2 to 2.8V at 1C and found favorable cycling properties in the LiNixCo0.9-xTi0.1O2 (0 <= x <= 0.6) compounds.
