Effect of Bi2O3 on the ion migration and interfacial properties of Li0.33La0.557TiO3 solid electrolytes
Source abstract
Abstract
The poor interface incompatibility with Li anode and low ionic conductivity have hindered perovskite-type electrolyte’s practical application. In this work, solid electrolytes of Li 0.33La 0.557TiO 3 + x wt% Bi 2O 3 for solid state batteries were prepared by solid-phase sintering method. The ionic conductivity of LLTO reaches a maximum of 2.71 × 10 –5 S·cm –1 at 1 wt% Bi 2O 3 doping. The critical current density of Li 0.33La 0.557TiO 3 + 1 wt%Bi 2O 3 can reach 0.16 mA and still operate normally after 300 h of cycling. Li 0.33La 0.557TiO 3 + 1 wt% Bi 2O 3 solid-state battery displays a high initial discharge capacity of 133.1 mAh/g and capacity retention of 98.0% after 40 cycles.
