Preparation, structure and electrical properties of Li1+4xTi2-xNbyP3-yO12(x= 0.1, 0.2, 0.3;y= 0, 0.1, 0.2, 0.3) ceramics

Abstract: The solid electrolyte compounds of Li1+4xTi2−xNbyP3−yO12 (x = 0.1, 0.2, 0.3; y = 0, 0.1, 0.2, 0.3) were synthesized by a solid state reaction and studied by X-ray diffraction from the powder. At room temperature all of the compounds display the hexagonal symmetry (space group R3c) with six formula units in the unit cell. The values of the binding, splitting energies and amounts of elements of Ti 2p, Nb 3d, P 2p, O 1s, and Li 1s core level of the ceramics' surfaces have been determined by XPS.

“…However, the conductivity of the base compound NaZr 2 (PO 4 ) 3 has been reported to be very low, below the applicable range and has poor sinterability [20]. Thus most studies have been carried out on partial as well as full substitutions of Na, Zr and P by higher valent elements of different radii [21][22][23] in order to improve the conductivities of the compositions. Such substitutions have lead to an enhancement of electrical conductivity [24,25].…”
