The solid solutions based on lanthanum manganite as the cathod materials for bismuth-containing solid electrolytes

Preparation, Structure and Physicochemical Properties of La0.95Bi0.05Mn1-yCuyO3+δ (у=0.1-0.4) and Composites with Bi2O3-Based Electrolytes

“…On the other hand, it was shown that preparation of composite materials containing lanthanum manganite and oxygenion conductor improved the performance of an electrochemical cell because of the extension of the triple-phase boundary region from the electrolyte / electrode physical interface into the electrode bulk [11,12] showed much lower polarization resistance values than composites with yttrium-stabilized zirconia [13]. In our previous works [14,15] in the process. Lanthanum oxide was weighted shortly after annealing.…”

“…Dilatometric measurements were carried out on rectangular bars with the length of 25 mm using a DIL 402 C Netzsch dilatometer in the temperature range 20-1000 °C with a heating rate of 2 °C / min. For electrical conductivity measurements, composite materials were prepared with bismuth-containing electrolytes Bi 4 [15]. All samples were coated by highly disperse platinum before measurements.…”
