Synergistic interphase regulation with a KSeCN bifunctional additive for stable and high-performance lithium–sulfur batteries

Year: 2025

Type: article

Abstract: deposition and suppressing Li dendrite growth. Correspondingly, LSBs with the KSeCN additive achieve a low capacity decay rate of 0.05% per cycle over 1000 cycles with excellent stability, while Li-S pouch cells operate stably for ∼140 cycles. Li‖Li symmetric cells exhibit a reduced hysteresis voltage and extended cycling lifetimes exceeding 1000 h. This work demonstrates a promising additive design strategy for high-performance LSBs through interfacial chemistry engineering.
