Abstract: | The electrical conductivity of the crystallized polyphosphates Li3Ba2(PO3)7, LiPb2(PO3)5, LiCs(PO3)2, and αLiK(PO3)2 has been determined at different temperatures by impedance spectroscopy. The conductivity, σ, spreads within a range of 1.59 × 10−8 to 1.79 × 10−7 S cm−1 at 573 K, and from 1.71 × 10−5 to 9.86 × 10−4 S cm−1 at 773 K. The transport should be assumed in the majority by the lithium ions with regard to the structural characteristics of these polyphosphates. The results are discussed and compared to the conductivity properties of other lithium ion conductors. |
