Overview

Multifunctional interlayer uses V2CTx MXene and porous carbon nanofibers to improve polysulfide management, suggesting a pathway for better battery performance.

Key Points

  • The V2CTx/PCNF interlayer significantly improves electrochemical performance and reduces the polysulfide shuttle effect.
  • High initial discharge capacity of 1319.4 mAh g−1 at 0.1 C, retaining 707.5 mAh g−1 at 5 C indicates excellent cycling stability.
  • The heterostructure formation enhances electron mobility and charge transport properties, vital for efficient battery operation.
  • The improved catalytic activity of V2CTx accelerates the sulfur reduction reaction, facilitating better energy storage.
