“…33 The capacity of Li 4 Ti 5 O 12 /Fe is 123?4 mAh g 21 at 5 C rate, much higher than that (59?5 mAh g 21 ) of the pristine material. The Fe modified Li 4 Ti 5 O 12 anode also showed superior cyclic stability with an initial discharge capacity of 141 mAh g 21 at 2 C rate, and still maintained 96?7% of its initial capacity after 300 cycles.…”

“…The empty 3d orbital of Ti 4z is the major cause of its poor electronic conductivity. Several approaches have been studied to enhance the conductivity such as nanoscaling, [9][10][11][12][13][14][15][16][17][18][19][20][21] cation doping and surface modification, 22,33 anion doping, 34,35 carbon and oxides coating, [36][37][38][39][40][41][42] binder modification 43,44 and comprehensive modification. [45][46][47] This paper presents a review of recent progress of Li 4 Ti 5 O 12 for lithium ion batteries.…”

In the past decades, Lithium ion batteries have drawn great attention due to the growing demands of electronic and information industries. Li 4 Ti 5 O 12 is considered as a promising anode material for Lithium ion batteries because of many advantages, including zero strain property, superior cycling stability, and outstanding safety. However, large scale applications of Li 4 Ti 5 O 12 are still hindered by some drawbacks including its low Li z diffusion coefficient and poor electronic conductivity. In order to overcome these obstacles, many methods have been investigated, such as nanoscaling, coating with other materials, doping with cations and anions, binder modification, and so on. This review focuses on the recent progress of Li 4 Ti 5 O 12 for Lithium ion batteries.
