Abstract

Nanoscale powders of LaFe_0.5Cr_0.5O₃ with perovskite structure were synthesized by the sol-gel combustion method in this work. From X-rays phase analysis obtained material consisted of one phase LaFe_0.5Cr_0.5O₃ (space group P m -3 m). The average size of RCS of test material is 21 nm. The specific surface area is 14 m²/g. The average particle size is 63.7 nm by approximation that particles form is spherical. Nanoscale powders of LaFe_0.5Cr_0.5O₃were tested as cathode material for lithium power sources. The cathode material demonstrates the specific power capacity of 571 A•h/kg when the discharge of the source is up to 0.5V.
