Inorganic Materials Aims and scope

Abstract

Many scientists have focused on the problem of improving the electrochemical performance (specific capacity, electrical conductivity, stability, and other characteristics) of cathode materials for lithium ion batteries. Nanostructuring and the use of cathode nanomaterials offer an effective solution to this problem. Here, we describe a new method of producing cathode materials for lithium ion batteries using nanoparticles with the composition Li1.2Ni0.2Mn0.4Co0.2O2/C, in which the mixed oxides have the form of core/shell nanoparticles (<100 nm in size) and a carbon layer serves as a shell, which increases the conductivity of the electrode material and improves its stability.
