Originální abstrakt

In this paper I present fundamental characteristics, principle, measurement and preparation cathode materials of Li-S batteries. S+C (sulfur+carbon) cathode material was prepared by simple solid-state reaction in ball mill. Content of sulphur was approximately 80 wt. % in final sample. Cyclic voltammetry and galvanostatic charge/discharge techniques were used for characterization of the samples. Initial discharge capacity observed for S+C sample was 600 mAh/gsulfur. Capacity loss for S+C sample after 30th cycles was 66 %. Cycling loss is due to insoluble polysulfide formation.
