Hierarchical Carbon Interlayer Design as Interfacial Stabilizer and <i>In-Situ</i> Solid-Electrolyte Infiltrate for High-Performance Solid-State Li-S Batteries.

ABSTRACT: A great deal of attention has been paid to lithium-sulfur (Li-S) batteries due to their high energy density (>2600 Wh kg^-1), elemental abundance, and environmental friendliness, which show great application prospects in a wide range of energy storage systems. However, the shuttle effect caused by traditional liquid electrolyte remains a problem handicapping the development of the Li-S battery. In-situ polymerized gel polymer electrolytes (GPEs) with high ionic conductivity, high-voltage stability, and interfacial compatibility are spotlighted to solve the shuttle effect for better electrochemical performance. Here, we use Al(OTf)₃ to initiate DOL ring-opening polymerization to form GPEs. A hierarchical carbon interlayer, comprised of superaligned carbon nanotub
