Abstract

Single crystals of lithium nitride1 have been studied as part of a programme to determine the effects of dopants on the ionic conductivity, and to assess the compatibility of lithium nitride with electrode materials in high energy density rechargeable cells. The ionic conductivity has been measured using complex impedance techniques and, in the course of this work, it has become clear that surface films on the lithium nitride crystals contribute strongly to the observed response. In particular, examination of complex impedance and related plots of electrical response versus frequency2 reveal the presence of two resistive and capacitative components arising from the response of the crystals themselves.
