Abstract

This work presents the effects of O₂ flow rate and S-doping on structural and electrochemical properties of LiNiO₂. Layered LiNiO₂ were prepared using a sol-gel method. It was found that oxygen plays an important role in the crystallization of layered LiniO₂. The deficiency of oxygen in the crystallization process induced the inclusions of impurities and cubic rock-salt structure in LiNiO₂ powders. For LiNiO₂ prepared at high O₂ flow rates, the electrode delivered high initial discharge capacity with a relatively good retention rate. S-doped LiNiO₂ not only stabilized the structural integrity of the electrode material, but also increased the electrode performance.
