Lithium iron phosphate plate-like particles of 100–150 nm sizes and to 10 nm thickness have been obtained by hydrothermal synthesis. It has been aim to investigate influence of ethylene glycol relative content and reaction medium temperature on the obtained-materials’ phase composition, crystalline and magnetic microstructure, surface condition and electrical properties. As determined, there is correlation between the materials’ morphology and their electrochemical properties. The reducing of a particle size and agglomeration degree leads to specific capacity growing for lithium power sources with cathodes based on synthesized materials. Key words: lithium iron phosphate, nanoparticles, morphology, conductivity, cathode, lithium power sources. https://doi.org/10.15407/nnn.15.04.0675 REFERENCES 1. A. Kumar, R. Thomas, N. K. Karan, J.
