Polysulfide dissolution and the correlated parasitic reactions are two major reasons for the capacity fading in the Li-S batteries. By understanding the mechanism of the electrochemical reactions in this system, one can introduce appropriate modifications in the components design which can effectively suppress or completely stop polysulfide migration or even their formation. In this talk a special attention will be paid to development of iono selective membranes designed and optimized for use in the Li-S batteries. Additionally, mechanism(s) of Li-S battery operation will be discusses based on the analytical work using operando XAS and UV-Vis measurements.
