A systematic study of Nasicon-type Li-i + XMXTi2 _ x(PO4)(3) (M: Cr, Al, Fe) by neutron diffraction and impedance spectroscopy

Popis výsledku v původním jazyce

A systematic study of Li1+ xMxTi2 x(PO4)3 with M=Al, Cr and Fe and 0 x 1 has been carried out by X-ray and neutron powder diffraction and by impedance spectroscopy. The analysis of the diffraction data allowed us to describe the disposition of the lithium atoms within the structure. They were found to occupy two different positions, the well-known M1 and a new position called M2. The addition of trivalent metals into the LiTi2(PO4)3 compound, even in small amount, gives rise to the liberation of the M1sites and simultaneous occupation of the M2 sites. This situation becomes more pronounced as the substituent content increases, meaning a higher delocalization of lithium atoms within the structure.Moreover, rising temperature also provokes the movementof lithium fromM1 to M2. The impedance spectroscopymeasurements allowed us to relate the electrical properties to the observations of the crystal structure. Both dc bulk and grain boundary ionic conductivity showa thermally activated beha
