(401f) Li-Ion Delivery Via Molecular Cages in Porous Liquid Type-II Electrolytes: Lithium-Sulfur Batteries

Rechargeable lithium-sulfur batteries are a promising technology with the high energy density up to 2600 Wh/kg and abundant sulfur resources. However, the accumulation of solid lithium sulfide and liquid lithium polysulfide at the cathode side hinders the mobility of Li+ ions, leading to decreased energy density and limited commercialization.
To address this issue, the use of porous liquid electrolytes has emerged as a potential solution due to their ability to capture and transport Li+ ions with high mobility. In this study, we will present the mechanism of solvation, transport, and electrical conductivity of lithium ions through porous liquid electrolytes and evaluate the potential of this new electrolyte system to enhance the energy density of lithium-sulfur batteries.
Our findings suggest that the use of porous liquid electrolytes can improve the energy density of lithium-sulfur batteries and pave the way for their commercialization.
