摘要	The NA1+xAlxTi(2-x)(PO4)(3)/C (x= 0, 0.05, 0.10, 0.20) composites serving as anode for aqueous sodium ion battery are successfully synthesized through a facile sol-gel route. The results indicate that introduction of proper amount of aluminum has no obvious effect on the structure and morphology of NaTi2(PO4)(3)/C. Among the four synthesized samples, Na1.1Al0.1Ti1.9 (PO4)(3)/C (NATP-0.10) exhibits the best electrochemical performance. NATP-0.10 delivers a discharge specific capacity of 115.8, 106.9, 98.4, and 89.1 mAh g(-1) at 2, 5, 10, and 20 C rate, respectively, and still retains 114.7 mAh g(-1) when the current density comes back to 2 C. Additionally, NATP-0.10 exhibits an initial discharge capacity of 102.9 mAh g(-1) and still retains a reversible capacity of 90.1 mAh g(-1) at 10 C rate after 200 cycles. Cyclic voltammetry and electrochemical impedance spectroscopy demonstrate the better electrochemical performance of NATP-0.10 is due to the faster sodium migration and enhanced electrochemical kinetics.
