Internal field-driven redox control and shuttle suppression via ferroelectric Ba0.9Sr0.1TiO3 in lithium–sulfur batteries

Iván Castillo, Sunny Choudhary, Diana C. Liza Castillo, Balram Tripathi et autres

The performance of lithium–sulfur batteries (LSBs) is critically hindered by polysulfide (PS) migration and sluggish redox kinetics. In this study, we present a field-assisted electrochemical enhancement strategy through the incorporation of ferroelectric Ba0.9Sr0.1TiO3 (BST) nanoparticles into sulfur/carbon black (S/CB) composite cathodes. The …
