Effect of Potassium on the Steadiness of the Structure of LiCoO2

The aim of this study was to improve the properties of cathode material for Li-ion batteries based on LiCoO2. As a method of manufacturing of the doped base material was chosen the solid phase reaction method, which has been already tested for the production of the basic material. The main goals were reducing the capacity loss during cycling of the material, maintaining the same or achieving higher capacity or increasing the current carrying capacity of the material LiCoO2 by doping the base material with varying amounts of potassium ions or by substitution of lithium by potassium.
