Abstract

To solve the intractable challenges of Li–S batteries, we synthesized MXene–NH₂CNT–BiOCl-x to be used as a sulfur host. The M–N–B-10%–S electrode exhibited superior electrochemical performance. In situ XRD measurement confirmed that the M–N–B-10%–S electrode displayed good cycle stability.
