A series of oxides of the composition LiNi y+δ Mn y+δ Co y−2δ O 2 (y=0.33; δ=0.025, 0.05, 0.075) were synthesized using the sol–gel method assisted by citric acid as chelating agent. The resulting nano-sized particles crystallize with a layered structure in the rhombohedral system. They exhibit an ordered rock-salt α-NaFeO 2 -type structure (R3¯m space group)...
A series of LiNixMnyCozO2 (x = y, z = 1 − 2y) oxides have been synthesized by “chimie douce” and investigated as positive electrodes in rechargeable lithium batteries. Layered LiNiyMnyCo1 − 2yO2 materials with high homogeneity and crystallinity were synthesized using the wet-chemical method assisted by carboxylic acid as the polymeric agent. The long range and local structural properties...
