Abstract

Compositions Li(Ni0.33Mn0.33Co0.33)1 – xFexO2 (0 ≤ х ≤ 1) of the LiNiO2–LiMnO2–LiCoO2–LiFeO2 concentration tetrahedron have been studied. Samples were synthesized by gel combustion with starch, which afforded, for the first time, the impurity-free stable solid solution LiNi0.2Mn0.2Co0.2Fe0.4O2 with an α-NaFeO2 layered structure used as a cathode matrix of lithium-ion batteries. Electrochemical testing of homogeneous LiNi0.2Mn0.2Co0.2Fe0.4O2 and the LiNi0.3Mn0.3Co0.3Fe0.1O2 sample with the lowest iron content has been carried out. The results expand the understanding of the possibility of saturation with iron of Li(Ni,Mn,Co)O2 with an α-NaFeO2 structure and indicate the feasibility of further studying the homogeneity volume and properties of the Li(Ni,Mn,Co,Fe)O2 solid solution.
