Заглавие : Structure and transport properties of Li7La3Zr2−0.75xAlxO12 superionic solid electrolytes Место публикации : Journal of Power Sources. - 2013. - Vol. 238. - С. 48-52 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): литий-ионная проводимость--фазовый состав--твердый электролит Аннотация: Samples of Li7La3Zr2−0.75xAlxO12 (x = 0.00, 0.05, 0.10, 0.15, 0.20, 0.25, 0.30) were synthesised using the citrate–nitrate method. The crystal structure of each sample was characterised using X-ray diffraction. Doping the samples with Al reduced the synthesis time. The cubic modification of Li7La3Zr2O12 was obtained by treatment at 1150 °C for 1 h. The conductivity of the ceramic samples was studied by complex impedance spectroscopy at 25–230 °C. The composition with x = 0.15 had the highest total conductivity, 3.4·10−4 S cm−1, at 25 °C. Доп.точки доступа: Il'ina, E. A.; Antonov, B. D.
