Abstract
The effects of mechanical activation in a planetary mill and the addition of fusible additives on the conduction properties of the Li1.3Al0.3Ti1.7(PO4)3 (LATP) solid electrolyte with the NASICON structure are compared. According to the results of impedance measurements, the mechanical activation increases the total conductivity of this material from 0.57 × 10–4 to 1.20 × 10–4 S cm–1, whereas the introduction of 5 wt % of fusible additives LiPO3 and Li2B4O7 increases the conductivity to 1.53 × 10–4 and 1.50 × 10–4 S cm–1, respectively. The electronic conductivity of samples does not exceed 10–9–10–8 S cm–1. According to the temperature dependence of the conductivity, the LATP sample containing Li2B4O7 (5 wt %) demonstrates the lowest activation energy equal to 0.29 eV.
