Abstract

These days, Li-S battery has been arisen as one of the key energy storage technologies due to its high theoretical energy density compared to conventional batteries. The present Li-S batteries suffer due to Li dendrite formation and capacity decay due to polysulfide dissolution effect, because of organic electrolytes used in the current research. Ceramic electrolytes are promising to prevent Li dendrite growth and polysulfide dissolution. Among different ceramic electrolytes garnet-type structure electrolytes are very promising because of its high lithium ion conductivity and stability with elemental Li. However, the high interfacial resistance with the electrode is the major bottleneck for the practical use of ceramic electrolyte. Polymer and ceramic hybrid electrolytes exhibit low interfacial resistance. In this talk, we will present development of novel hybrid electrolytes for all-solid-state Li batteries, along with new methods to produce S cathodes with minimal polysulfide shuttle effect.
