Overview

Randomized trial demonstrates enhanced lithium deposition in anode-free batteries, indicating improved energy density.

Key Points

  • This study aims to address the challenges of capacity decay and dendritic lithium growth in anode-free lithium metal batteries.
  • Designed a Cu@TiN-MWCNT interfacial layer on Cu foil for lithium deposition/stripping.
  • Utilized TiN nanoparticles to reduce Li nucleation overpotential and COOH-functionalized MWCNTs for conductivity.
  • Evaluated battery performance over 150 cycles at 3 C with specific focus on capacity retention and coulombic efficiency.
  • Li/Cu@TiN-MWCNT||LFP cell maintained a specific capacity of 144.15 mAh g−1 after 150 cycles at 3 C.
  • AFLMB exhibited high capacity retention of 51.41% after 80 cycles and coulombic efficiency of 98.67%.
