sample delivers the initial discharge capacity of 126.7 mAh g

at 0.1 C in the voltage range of 1.8–4.0 V, and its capacity retention is 75.3% after 100 cycles, which is 63.7% higher than that of the pristine. Whereas at 10 C rate, the optimized sample presents the maximal discharge capacity of 72.8 mAh g
−1
with an excellent high-rate cycling stability of 91.6% retention after 100 cycles, correspondingly the pristine shows 61.4 mAh g

and 73.1% retention. These excellent electrochemical performances are ascribed to better structural stability, and lower charge transfer resistance and higher Na

diffusion coefficient after Nb

doping. Therefore, the Nb

-doped P2-type cathode materials can be deemed as a beneficial improvement for researches on sodium-ion batteries. |
