The loss of the sulfur cathode material through dissolution of the polysulfide into electrolyte causes a significant capacity reduction of the lithium-sulfur cell during the charge-discharge reaction, thereby debilitating the electrochemical performance of the cell. We have addressed this problem by using a chemical and physical approach called reduction of polysulfide dissolution through direct coating functional inorganic (graphene oxide) or organic layer (polyethylene oxide) on electrode since the deposition of external functional layer can chemically interact with polysulfide and physically prevent the leakage of lithium polysulfide out of electrode. Through this approach, we obtained a composite electrode for a lithium-sulfur battery (sulfur: 60 %) coated with uniform and thin external functional layers where the thin external layer was coated on the electrode by solution coating and drying by a subsequent heat treatment at low temperature (~80 °C).
