- •
Cox/Li3Ti4Co1−xCrO12 was prepared by solid-state method under reducing atmosphere.
- •
The Co modified samples showed excellent electrochemical performance.
- •
The enhanced performance can be explained by the improved conductivities.
- •
Oxygen vacancies were generated during the calcination under reducing atmosphere.
- •
Oxygen vacancies are responsible for the promoted conductivities.
