Effect of surface modifiers in improving the electrochemical behavior of LiNi0.4Mn0.4Co0.2O2 cathode

- Bi2O3 and In2O3 have been explored for the first time as surface modifiers.
- Protective metal oxide inter-connect layer reduces irreversible capacity loss.
- Extended potential window (5.0 V) and rate capability (3 C) have been realized.
- Cycling and structural stability up to 100 cycles have been demonstrated.
- Bi2O3 coated LiNi0.4Mn0.4Co0.2O2 cathode performs better electrochemically.
