Design and evaluation of novel Zn doped mesoporous TiO2 based anode material for advanced lithium ion batteries

Nb-Doped TiO2 Nanofibers for Lithium Ion Batteries

“…This result is in line with the assumption that Nb partially substitutes Ti atoms in the anatase lattice whereas the deviation of the peak minimum (≈ 22 at%) from the expected Nb-content (≈ 10 at%) is considered acceptable regarding the width of the minimum and assumptions and simplifications made in the computational approach. thesis method to achieve specific morphology 26,32,58,59 or elaborate electrode formulation 20,[60][61][62] are superimposing to the effect of dopant and are therefore hardly comparable to our results. It is needless to say that a specific work on electrode formulation will probably bring rate capability and capacity retention improvements.…”

Fast synthesis of uniform mesoporous titania submicrospheres with high tap densities for high-volumetric performance Li-ion batteries

“…The peak at~1.71 V is characteristic of the biphasic transition from tetragonal anatase (I41/amd) to orthorhombic Li0.5TiO2 (Imma) and is consistent with the galvanostatic curve. In addition to the two aforementioned typical peaks, there is another pair of peaks at~1.80/1.45 V, probably arising from the Li storage on the surface/interface of mesoporous TiO2, which has been previously reported [17,37,38].…”

“…The second stage exhibits an obvious discharge plateau at~1.75 V, resulting from the phase-coexisting domain of the Li-poor tetragonal LixTiO2 and the newly formed Li-rich orthorhombic Li0.5TiO2 (Imma) with further Li insertion [8,11,16]. The last stage-below 1.75 V-involves the further storage of Li ions on the surface/interface of TiO2 [17,37,38], which leads to an inconspicuous peak at~1.5 V. The first discharge capacity is 273.4 mA h g −1 , and the subsequent charge capacity is 243 mA h g −1 , leading to a Coulombic efficiency of 88.9% for the first cycle, which is probably due to the trapping of some Li ions within UMTSs. However, the efficiencies increase to 95.6% and 99.1% in the second and third cycles, respectively.…”

Synthesis and characterization of nanostructured lithium titanate by simple peroxo route

“…The most commercially popular cathode materials such as lithium cobalt oxide (LiCoO 2 ) [7], lithium manganese oxide (LiMn 2 O 4 ) [8], lithium iron phosphate (LiFePO 4 ) [9][10][11], vanadium oxide (VO 2 ) [12], vanadium pentoxide (V 2 O 5 ) [13][14][15], lithium trivanadate (LiV 3 O 8 ) [16,17] are used in Li-ion batteries. Recently, researchers are trying to develop the cost effective electrode materials such as manganese oxide (MnO 2 ) [18][19][20][21], titanium oxide (TiO 2 ) [22][23][24][25][26][27][28][29][30], molybdenum dioxide (MoO 2 ) [31] and graphite to use as anode materials in Li-ion batteries. Lithium ion batteries could also be used in hybrid electric vehicles (HEVs) and electric vehicles (EVs).…”
