Stability of charged Li1.2Ni0.2-xMn0.6-xCo2xO2 at high temperature was higher than that of charged LiNi0.8Co0.2O2.
- •
Stability of charged Li1.2Ni0.2-xMn0.6-xCo2xO2 was improved by substituting Co with Ni and Mn.
- •
Oxygen release behavior from charged Li1.2Ni0.2-xMn0.6-xCo2xO2 at high temperature changed during cycles.
