Comparison of material properties of LiCoO2 doped with sodium and potassium

Abstract

The aim of this study was to improve the properties of cathodic material for lithium-ion batteries based on LiCoO2. The solid phase reaction method was chosen as a manufacturing method of the doped base material. This method has already been tested for the production of basic material. Materials selected from the group of alkali metals were chosen as the doping elements. The main objective was to use these added elements for stabilizing the structure of the LiCoO2 material and for limiting the process of their degeneration.
