Abstract	The instability of anode materials during cycling has been greatly limiting thelifetime of aqueous rechargeable lithium batteries (ARLBs). Here, to tackle thisissue, mesoporous LiTi2(PO4)3@Ccomposites with a pore size of 4 nm and a large BET surface area of165 m2 g−1 have beensynthesized by a novel two-step approach. The ARLB with this type ofLiTi2(PO4)3@C anode, commercialLiMn2O4 cathode and 2 M Li2(SO4)aqueous solution (oxygen was removed) exhibited superior cycling stability (acapacity retention of 88.9% after 1200 cycles at 150 mAg−1 and 82.7% over 5500 cycles at 750 mAg−1) and excellent rate capability (dischargecapacities of 121, 110, 90, and 80 mAh g−1based on the mass of LiTi2(PO4)3 at 30, 150, 1500,and 3000 mA g−1, respectively). As verified,the mesoporous structure, large surface area and high-quality carbon coating layerof the LiTi2(PO4)3@C compositecontribute to the breakthrough in achieving excellent electrochemical properties forARLB.
