Abstract
All-Solid-State-Lithium-Sulfur-Batteries(ASSLSBs) are the most promising candidate for next generation secondary battery because of its high theoretical specific capacity of Lithium metal (3860 mAhg-1) and elemental sulphur (1672 mAhg-1). However, the shuttle effect of Li-S battery is the major obstacles of commercialization. And there are still remaining safety issues due to dendrite formation during lithium deposition. Adopting solid state electrolyte can be a solution to these issues. Recent studies of all-solid-state-batteries have achieved high capacity and good stability. But there are still hindrances of interface problems between solid electrolyte and active materials. The interfacial issues of solid electrolytes can be solved by applying lithium metal powder. In this study, we fabricate composite electrode which have large specific contact area as well as intimate contact of electrode component by using solid electrolyte and lithium metal powder. Surface of lithium metal powder is modified by an ion conductive polymer material to prevent side reaction of solid electrolyte and lithium metal powder. This study can provide a new way of producing the surface modified lithium powder as an anode material for All-Solid-State-Lithium-Sulfur-Batteries.
