Paper Title:
Electrochemical Performance of Al2O3-Coated LiNi1/3Co1/3Mn1/3O2 Cathode Materials for Li-Ion Batteries
  Abstract

Al2O3-coated LiNi1/3Co1/3Mn1/3O2 powders with excellent electrochemical performance have been synthesized. The electrochemical performance of Al2O3-coated LiNi1/3Co1/3Mn1/3O2 electrodes has been studied as function of the level of Al2O3 coating. Coated LiNi1/3Co1/3Mn1/3O2 samples shows higher discharge capacity and better capacity retention than the base one. Among the coated samples, 1.0mol% coated sample exhibits the best electrical performance. It presents an initial discharge capacity of 174.5 mAh g-1 over 2.5~4.4V, and 84.7% capacity retention after 30 cycles over 2.5~4.6V.
