摘要: The garnet-type Nb-doped cubic lithium ion-conducting solid Li6.75-xLa3Zr1.75Nb0.25O12–0.5x (LLZ-Nb) was prepared with 0.46 wt% Al2O3 using a sol-gel precursor. LLZ-Nb sintered at 1,150°C for 36 h exhibited bulk conductivity of 6.13 × 10−4 S cm−1 and grain boundary 7.76 10−3 25°C. cell resistance Li/LLZ-Nb/Li gradually increased storage time over 5 months. increase in attributed to both the interfacial between electrode. showed short-circuit 280 s polarization 0.5 mA cm−2 no 41 0.1 cm−2. stable saturated LiOH LiCl aqueous solution.
