N2 - The layered Nickel-rich LiNixMyO2 (Ni ≥60%) cathodes have attracted much attention owing to their high energy density, promising cycle property and low cost. Nevertheless, their electrochemical performances greatly depend on the synthesis conditions, especially for the ratio of lithium to transition metal (Li/TM). Herein, we have systematically investigated the influence of Li/TM on structure and electrochemical performance of LiNi0.9Co0.1O2 cathodes. The optimized LiNi0.9Co0.1O2 (Li/TM is 1.02) exhibits highest initial capacity of 189.8mAh g-1 at 1 C and much better capacity retention of 82.19% after 100 cycles between 2.8 and 4.35 V at 1 C.
