Synthesis of almost stoichiometric nanosized cathode materials Li1-xNi1+xO2 by a combined method and study of their physical and electrochemical characteristics: IR spectra
Almost stoichiometric nanosized material with the composition Li1-xNi1+xO2 were synthesized by the combined method. The studied sample was prepared with the following conditions: Li:Ni ratio 10:1, thermal treatment temperature T = 700C, treatment time t = 60 min, composition Li0.98Ni1.02О2. IR absorption spectra were recorded on a single-beam Fourier transform IR spectrophotometer IR Tracer-100 (Shimadzu Corporation, Japan) in the wavelength range 4000 – 400 cm-1. Lithium nickelate sample were pressed with KBr in tablets.
