英文摘要	Spinel Li4Ti5O12 (LTO) is the safest commercial anode for power batteries owing to its stability, zero strain and Li dendrites free, but its inherent insulating characteristic seriously limits its high-rate capability. Nitrogen-doped LTO/C (NCLTO) is firstly synthesized by thermal decomposition of an amorphous titanate crosslinking g-C3N4 inorganic polymer and then reaction with lithium salts utilizing a simple solid state reaction. The doping nitrogen has a fair distribution which allows fast transportation of lithium ions, and the content of nitrogen is tunable through control the decomposition time of g-C3N4. It exhibits a better high-rate capability and cycling performance than that of LTO, which delivers a high capacity of 122 mAh g(-1) after 500 cycles at a current density of 10C with 102% capacity retention while the capacity retention of only 50.5% for pure LTO. Furthermore, the NCLTO also exhibits an overwhelming advantage of high-rate performance than LTO owing to the introduced conductive nitrogen-doped carbon and TiN. (C) 2017 Elsevier Ltd.
