Zbihlei L. Physico-chemical properties of nanocomposites iron fluoride / carbon.

The paper presents results of investigations of the crystal structure, morphology and electrochemical properties of iron fluoride with nano-sized particles and their composites with carbon synthesized, by using liquid-phase methods. The influence of the synthesis conditions and ultrasonic dispersion on electrochemical characteristics of the materials was found. And also presented the results of testing of submissions received as part of cathode compositions of lithium-ion power sources. For the first time the model of structural change in the dehydration of the received material by hydrothermal b-FeF3·3H2O was constructed and conditions of phase transition of b-FeF3·3H2O - НТВ-FeF3·0.33H2O - r-FeF3 were traced. The influence of ultrasonic dispersion on the morphological and structural properties of iron fluoride were defined. The morphological characteristics of nanocomposites influences its magnetic structure. The model of the LPS with cathode based on nanocomposites of iron fluoride / acetylene black was created. The coefficients of diffusion of ions Li+ in the structure of the cathode material were calculated. Also shows the growth efficiency of the use of iron fluoride subjects sonicated and their composite materials with carbon as compared to the baseline. The coefficients of volume and percolation diffusion of ions Li+ in the structure of the cathode material were calculated.
