Abstract
The layered compounds, Li(Co0.8Ni0.2−yAly)O2 (y ≤ 0.02) were synthesized by a self-sustaining solution combustion method with hexamethylenetetramine (HMTA) as a fuel. The prepared compounds were characterized by means of XRD, SEM and DSC studies. The precursors were also subjected to thermogravimmety (TG) analysis. Li[Co0.8Ni0.2−yAly]O2 (y ≤ 0.02)/Li cells have been assembled and were subjected to cycling studies at different C-rates. The substitution of Al3+-ions has considerably increased the structural and thermal properties of the compound.
