Ionic conductivity of lithium phosphate doped by lithium bromide

Abstract EN

Ionic conductivity of the new system (LiP03) i_x- (LiBr) x where 0.

15 < x < 0.65 moles have been measured, when plotted as a function of temperature, the conductivity of the materials follows a straight line on an Arrhenieus diagram.

The ionic conductivity has been measured by using the method of plotting diagrams of impedance in the plane complex.

The measurements were carried out over the range of temperature (100°C - 500°C).

The material exhibit a large enhancement in the ionic conductivity due to the effect of dopant by LiBr.

With respect to the amount of LiBr, the results show a maximum of conductivity at x =0.55 mole corresponding to a minimum of activation energy (Ea = 0.572 Ev).
