Abstract:
LiNi1-yTlyO2 (y = 0.005, 0.01, 0.025, 0.05 and 0.1) were synthesized by milling and solid-state method. Their electrochemical properties were then compared with those of LiNi1-yMyO2 (M = Ga3+ and In3+). All the samples had the structure. LiNi0.95Tl0.05O2 has the largest first discharge capacity 179.8 mAh g-1 and the discharge capacity 113.8 mAh g-1 at the 20th cycle. LiNi0.995Tl0.005O2 has the smallest first discharge capacity 125.4 mAh g-1. The samples exhibit similar cycling performances. LiNi0.975Ga0.025O2 and LiNi0.9In0.1O2 had the best electrochemical properties among the samples substituted by the same element, respectively. Among LiNi0.975Ga0.025O2, LiNi0.9In0.1O2 and LiNi0.95Tl0.05O2, LiNi0.95Tl0.05O2 has the largest first discharge capacity, but has the worst cycling performance. LiNi0.975Ga0.025O2 has the smallest first discharge capacity, but has the smallest capacity degradation rate 0.70 mAh g-1 cycle-1.
