Many scientists have focused on the problem of improving the electrochemical performance (spe cific 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 Li 1.2 Ni 0.2 Mn 0.4 Co 0.2 O 2 /C, in which the mixed oxides have the form of core/shell nano particles (<100 nm in size) and a carbon layer serves as a shell, which increases the conductivity of the elec trode material and improves its stability.
