Abstract: The rapid development of electrical wearable devices and electric cars is forcing battery industry into developing more efficient and economic energy storage systems. One of the attractive candidates among these systems are Li-S batteries. These next-generation high-energy rechargeable batteries are promising mainly thanks to their high theoretical energy density and low cost. However, the safety concerns of lithium anode, insulating properties of sulfur and rapid drop of capacity during cycling due to dissolution of polysulfides are key limitations of practical use. A cell composed of metal lithium anode and carbon doped sulfur cathode in environment of *LiTFSI:LiNO3 DME:DOL electrolyte can be considered a basic lithium-sulfur cell. This type of lithium-sulfur cell is used in many scientific publications. This paper discusses the production of positive electrodes for lithiumsulfur cells and modifications of their production.
