Study of the influence of the phase composition and crystal structure of Fe_xNi_100-x nanostructures on the efficiency of using lithium ion batteries as anode materials

Abstract

The results of the efficiency of using Fe x Ni 100􀀀x nanotubes as anode materials for lithium-ion batteries have been obtained. In the course of research, it was found that an increase in the concentration of nickel in the structure to 40 and 60 at.% leads to a sharp increase in the resource number of cycles by more than two times in comparison with iron nanotubes. Such a difference in the resource lifetime is due to the higher stability of Fe x Ni 100􀀀x nanotubes with a nickel concentration of more than 40 at.% to destruction, as well as resistance to oxidation.
