Nitridated mesoporous Li4Ti5O12 spheres for high-rate lithium-ion batteries anode material

“…10 −9 -10 −13 cm 2 s −1 ) are relatively low and prohibitive for achieving high-rate performance [7,8]. In order to realize the high-power application, many efforts have been made to ameliorate the lithium-ion diffusion and electron transfer efficiency, including doping with foreign atoms [9][10][11], synthesizing nanostructures [12][13][14][15][16], and introducing electronically conductive coatings [17][18][19][20]. Synthesizing nanostructured LTO particles or sheets is one of the most efficient strategies to reduce the lithium-ion diffusion and electron transport pathway so as to improve their rate capability [12,13].…”

Sol–gel preparation and electrochemical properties of La-doped Li4Ti5O12 anode material for lithium-ion battery

“…As reported [21], doping with a certain amount of La 3+ can enhance the rate property of Li 4 Ti 5 O 12 . Gao et al [19] had prepared the spherical lanthanum (La)-doped Li 4 Ti 5 O 12 materials by an "outer gel" technique, but the large grain size may hinder the Li + diffusion at a high rate.…”

“…It can be seen that the (111) plane shifts to lower diffraction angles after La 3+ doping, indicating that some La 3+ ions can enter into the crystal lattice. Yi et al [21] reported that La 3+ only substitute Ti 3+ at the octahedron (16d) site. In this work, we have found that except for the (220) peak, the intensity of all other peaks has been weakened after doping.…”
