抄録

Lithium nickel vanadate and lithium cobalt vanadate with various lithium concentrations have been prepared by a solid-state reaction method. X-ray photoelectron spectroscopic analysis of both samples indicates a reduction in the oxidation state of vanadium with increasing lithium composition. Conductance spectra reveal the low coulombic repulsive force between lithium ions for Li_1.0NiVO₄ and Li_1.2CoVO₄. Modulus spectra indicate an increase in available sites for lithium motion with an increase in lithium content for both samples.
