Tailoring Artificial Solid Electrolyte Interphase via MoS2 Sacrificial Thin Film for Li‑Free All‑Solid‑State Batteries

Caption

  • We present the first-ever fabrication of the anode-free all-solid-state battery (AFASSB) structure using a MoS2 sacrificial layer.
  • The addition of an MoS2 sacrificial layer to AFASSBs could decrease the nucleation overpotential of Li and enable favorable Li formation at the interface owing to the formation of an interlayer comprising Li2S and Mo metal.
  • The AFASSB full cell assembled with LiNi0.6Co0.2Mn0.2O2 cathodes operated successfully, demonstrating superior cycling stability and enhanced capacity relative to the cells with SUS.
