Abstract
LiNi1 – y − zCoyMnzO2 (y = 0.25, 0.35, 0.5, 0.6; z = 0.1, 0.2), LiNi0.63Cu0.02Co0.25Mn0.1O2, LiNi0.65Co0.25Mn0.08Al0.02O2, LiNi0.65Co0.25Mn0.08Mg0.02O2 and LiNi0.65Co0.25Mn0.08Al0.01Mg0.01O2 cathode materials were synthesized by a soft chemistry EDTA-based method. Structural and transport properties of pristine and delithiated materials (LixNi0.65Co0.25Mn0.1O2, LixNi0.55Co0.35Mn0.1O2 and LiNi0.63Cu0.02Co0.25Mn0.1O2 oxides) are presented. In the considered group of oxides there is no correlation between electrical conductivity and the a parameter (M–M distance in the octahedra layers). The results of electrochemical performance of cathode materials are presented. The best stability during first 10 cycles was obtained for Li/LixNi0.63Cu0.02Co0.25Mn0.1O2 cell due to enhanced kinetics of intercalation process.
