Facile strategy to fabricate Na2Li2Ti6O14@Li0.33La0.56TiO3 composites as promising anode materials for lithium-ion battery

Construction of Carbon-Coated LiMn0.5Fe0.5PO4@Li0.33La0.56TiO3 Nanorod Composites for High-Performance Li-Ion Batteries

“…The possible reason is that as the content of LLTO increases, the LLTO layer on the surface of LMFP becomes thicker and then hinders the initial diffusion of lithium ions. The similar conclusion can be found in the reported MXene decorated carbon coated LiFePO 4 and Li 4 Ti 5 O 12 –Li 0.33 La 0.56 TiO 3 …”

“…However, high content of carbon in electrode materials will decrease the tap density, which will affect the volume energy density. Recently, lithium-ion conductive solids such as Li 3 x La 0.66– x TiO 3 , LiAlO 2 , LiNbO 3 , Li 2 ZrO 3 , and Li 3 PO 4 have been used to modify electrode materials because they can provide a stable barrier coating without sacrificing Li + ions at the interface. Among them, the Li–La–Ti–O series materials (Li 3 x La 0.66– x TiO 3 ) have been considered as one of the fastest Li-ion conductors, which show fast transmission of Li ions and an excellent bulk ionic conductivity.…”

Lithium lanthanum titanate perovskite ionic conductor: Influence of europium doping on structural and optical properties

“…Given the fact that the levels involved in the transitions are derived from the same configuration (4f 6 ), it would be quite expected that all these transitions were forbidden. Nevertheless, the ligand field (odd) associated with the chemical environment where the Eu 3+ ion is located has the property of mixing levels of opposite parity settings, relaxing the selection rules for the electric dipole transitions.…”

“…La 2/3-x Li 3× TiO 3 system has been extensively studied for use in lithium batteries as electrodes, solid electrolytes and as separators in lithium-air batteries as a result of its high ion mobility, which can reach up to 10 −3 S cm −1 at room temperature [1][2][3]. Based on the work conducted by Inaguma et al [4] which reported high mobility of lithium ions in La 0.55 Li 0.35 TiO 3 composition, several mechanisms for the conduction of La 2/3-x Li 3× TiO 3 compounds have since been proposed associated mainly with structural considerations, conductivity measurements and theoretical models aiming at justifying the high ionic conductivity at room temperature [5][6][7][8][9][10][11][12][13][14]. Despite considerable understanding has been achieved in LLTO compounds, detailed comprehension of lithium ion diffusion as well as the influence of composition and associated local structural changes on diffusion is still lacking [14].…”

Solid electrolyte interphase formation between the Li0.29La0.57TiO3solid-state electrolyte and a Li-metal anode: anab initiomolecular dynamics study

“…20 In 1993, Inaguma et al 21 discovered that Li 0.34 La 0.51 TiO 2.94 showed high ionic conductivity at room temperature, 2 Â 10 À5 S cm À1 , then, several compositions of LLTO have been proposed as high ionic conductors and potential solid electrolytes materials. [22][23][24][25] Several Li 2/3Àx Li 3x TiO 3 structures were tested, obtaining ionic conductivities from 10 À3 to 10 À6 S cm À1 . 26,27 Despite LLTO high conductivity, there are still some issues regarding the use of LLTO as a workable electrolyte.…”
