摘要：

Single phase lithium phosphorus nitrides Li7NP2 and LiN P2 were prepared by reaction of the binary nitrides P3N5 and Li3N at 620 and 800°C, respectively. The compounds were identified by X-ray powder diffraction techniques. The lithium ion conductivity of both compounds was investigated by complex impedance spectroscopy in the temperature range between 50 and 350°C. The specific conductivity was found to be σ(400 K)=1.7×10-5 and 6.9×10-7 ω-1 cm-1 for Li7PN4 and LiPN2, respectively: The activation energy was 46.7 kJ/mol for Li7PN4 and 58.9 kJ/mol for LiPN2. © 1990.
