Br-doping Li 4 Ti 5 O 12 (Li 4 Ti 5 O 11.7 Br 0.3 ) is fabricated by conventional solid state method and shows enhanced cycling performance compared with pristine Li 4 Ti 5 O 12 . After thermal nitridation for 90 min in NH 3 , the Li 4 Ti 5 O 11.7 Br 0.3 electrode exhibits better rate capability and excellent cycling performance. It delivers a reversible capacity of 138 mAh g −1 and 104 mAh g −1 after 100 cycles at 10C and 20C, respectively, which is approximately four and seven times higher than those of pristine Li 4 Ti 5 O 12 at the same current rates. This work indicates the feasibility of improving cycling performance and rate capabilities of Li 4 Ti 5 O 12 through controlling both surface termination and bulk doping procedures.
