Synthesis and electrochemical performance of F-doped Li4Ti5O12 for lithium-ion batteries

“…4(a). For Li 4 Fig. 8 shows the cycling performance and coulombic efficiency of Li 4 Ti 5 O 12−x F x (x = 0.3) electrode at the current density of 340 mA g −1 over 500 cycles.…”

“…In this paper, we have successfully synthesized the wellstructured cubic spinel Li 4 Even at a current density of 340 mA g −1 , the specific discharge capacity is still 138 mAh g −1 over 500 cycles. All the results suggest that the F doping can efficiently maintain the electrochemical performance and the Li 4 Ti 5 O 12−x F x (x = 0.3) material seems to be a promising anode material for lithium ion batteries.…”

“…However, the Li 4 Ti 5 O 12 material has an inherently insulating property due to the empty Ti 3d state with band energy of about 2 eV which causes LTO suffering from a series problem, such as low energy density, poor rate capability and low electric conductivity (about 10 −9 Scm −1 ) [3,4]. As a result, many researches mainly concentrate on morphology tailoring, size control, surface modification and ion doping to improve the rate capability of LTO materials [5][6][7][8][9][10].…”

Characterization of LiMn2O4 thin films grown on Si substrates by pulsed laser deposition

“…However, a pure thin film is the best choice for the fundamental studies, without the effects of additives such as conductive materials and organic binders. Although LiMn 2 O 4 thin films were prepared by various deposition techniques such as electron-beam evaporation [9], electrostatic spray deposition (ESD) [10], radio frequency (rf) sputtering [11,12] and pulsed laser deposition (PLD) [13,14], all these studies mainly investigated the electrochemical properties and effects of growth conditions and post-treatments. In the present paper, LiMn 2 O 4 thin film are deposited on Si substrate by PLD and characterized.…”

Enhanced Performance of “Flower‐like” Li4Ti5O12 Motifs as Anode Materials for High‐Rate Lithium‐Ion Batteries

“…[5,6] However,t he inherently sluggishl ithium-ion diffusion coefficient of bulk Li 4 Ti 5 O 12 (10 À9 to 10 À13 cm 2 s À1 ) [7,8] coupled with its low intrinsic electronic conductivity (10 À13 Scm À1 ) [9,10] greatlyl imit its rate capability. Therefore, two strategies have been typicallye mployedt o improvethe rate performance of Li 4 Ti 5 O 12 anodes.…”
