Cathode materials based on almost stoichiometric lithium nickelates have been synthesized. Samples were nanosized. The materials composition was Li0.98Ni1.02О2 (Sample 4) and Li0.79Ni1.21О2 (Sample 6). The sample 4 was synthesized at the following conditions: Li:Ni = 10:1; threatment temperature T=700C; treatment time t = 60 min. The sample 6 was synthesized at the following conditions: Li:Ni = 10:1; threatment temperature T=700C; treatment time t = 30 min. SEM images were obained by SEM LEO-420 scanning electron microscope (Carl Zeiss, Germany). The ScanMaster (National research nuclear university (MEPHI), Moscow Engineering Physics Institute, Russia) program was used for mathematical processing of images and calculation of grain sizes.
