In this paper, Li1–xTi2(PO4)3/C composites (x = 0, 0.03, 0.05, 0.07) were synthesized by sol-gel approach, and the influence of Li vacancy on electrochemical performance of LiTi2(PO4)3/C anode for aqueous rechargeable lithium battery was studied. Li vacancy hardly influences the crystal structure and morphology of the composite. Electrochemical measurement results demonstrated that Li1–xTi2(PO4)3/C exhibited better performance compared with pristine LiTi2(PO4)3/C, and Li0.95Ti2(PO4)3/C has the best properties. Li0.95Ti2(PO4)3/C delivered the discharge capacity of 104.3, 92.6, and 7...
