The spinel LiMnZ0 4 has been studied extensively because of its high possibility of being commerciali ed as a cathode material for secondary lithium batteries. In the present investigation substitution of a large amount of manganese with nickel (LiMnz_. i,.04) (0 < x < 0.5) has been conducted using the solid state reactions of LizCOv MnOz and Niz0 3 at 1123 K. To understand the reaction mechanism, DTA and TG curves were taken. The variation of i content to manganese indicates high thermal stability of nickel substituted spinel.
