Development of promising cathode materials based on modified spinels for Li-ion accumulators. / E. I. Kachibaia, T. V. Paikidze, R. A. Imnadze, Sh. S. Japaridze. – 2021–2022. – # 21/22. – pp. 163-166. – eng. Promising cathode materials based on iron-modified LiMexNi0.5–xMn1.5O4 (where Me = Fe and x = 0.1 – 0.4) type compounds have been developed. Conditions for phase pure nanostructured samples with cubic spinel structure obtaining based on LiCO3, Mn2O3 and Ni2O3 initial reagents are optimized. For this purpose, a number of solid-state synthesis methods in the 180 – 700 °C interval are used. Cathode materials based on Fe–Mn are economically attractive due to the high abundance of Mn and Fe in nature. Cathode materials for lithium–ion batteries containing iron, nickel and manganese can be a promising alternative to commercial LiCoO2 and LiNiO2 samples. Tab. 1, Ref. 2.
