- •
Li-rich cathode materials with different layered-spinel ratios are synthesized.
- •
Gradient calcination processes are designed to control the phase ratios.
- •
The calcination time and temperature jointly influence the phase ratios.
- •
The electrochemical performances with various phase components are studied.
