Abstract
Compound (7Li, 1H) NMR and impedance spectroscopy methods are used to study the ion mobility and conductivity in a complex of the composition Li(NH3CH2COO)(NO3) (I), which has a layered crystal structure. The character of ion motions in lithium and proton sublattices with temperature variation is considered; the types of motions and temperature ranges in which they occur are determined. It is found that above 350 K the dominant process in the lithium sublattice of the compound is Li+ ion diffusion. Possible migration paths of lithium ions in the lattice of the compound are analyzed. The conductivity of the compound is found to be 2.4x10-6 S/cm at 393 K.
