Original Abstract

LiCoO2 is one of the most commonly used cathode materials in lithium-ion accumulators. There are also some disadvantages given by its structure beside a number of advantages. One of them is its instability. This article focuses on improving its stability from the perspective of cyclability and stability on higher load depending on the time elapsed from the synthesis. Solid state reaction method was chosen as the method of synthesis of this material and as the method of stabilizing the structure by doping by other element - in this case by potassium. Materials were also study by SEM microscopy for the comparison of structural changes of doped material.
