A facile synthesis of cobalt-free nickel-rich ternary cathode material LiNi0.9Fe0.05Al0.05O2 for lithium-ion batteries

To develop high-energy density and inexpensive LIBs, it is exigent to hunt for inexpensive cathode materials with high capacity and operating voltage. Herein, cobalt-free Ni-based ternary material LiNi0.9Fe0.05Al0.05O2 was prepared by a modified rheological phase reaction method. LiNi0.9Fe0.05Al0.05O2 exhibits high discharge capacity of 195 mAh g−1 at 0.1C, better rate capability and cyclability. LiNi0.9Fe0.05Al0.05O2 is competitive among Ni-based cathode materials based on the comprehensive consideration of cost and electrochemical performance.
