Comprehensive Design of the High-Sulfur-Loading Li-S Battery Based on MXene Nanosheets.

ABSTRACT: The lithium-sulfur battery is the subject of much recent attention due to the high theoretical energy density, but practical applications are challenged by fast decay owing to polysulfide shuttle and electrode architecture degradation. A comprehensive study of the sulfur host microstructure design and the cell architecture construction based on the MXene phase (Ti₃C₂T_x nanosheets) is performed, aiming at realize stable cycling performance of Li-S battery with high sulfur areal loading. The interwoven KB@Ti₃C₂T_x composite formed by self-assembly of MXene and Ktejen black, not only provides superior conductivity and maintains the electrode integrality bearing the volume expansion/shrinkage when used as the sulfur host, but als
