BaTiO3 Nanoparticle‑Induced Interfacial Electric Field Optimization in Chloride Solid Electrolytes for 4.8 V All‑Solid‑State Lithium Batteries (IMAGE)
Caption
- Time efficient ball milling achieves uniform BaTiO3 ( coating without sacrificing ionic conductivity (1.06 mS cm−1).
- Ferroelectric BTO coating suppresses Li2.5Y0.5Zr0.5Cl6 (LYZC decomposition at 4.8 V via electric field modulation, enabling 76% capacity retention after 150 cycles.
- BTO effectively minimizes the formation of interfacial ZrCl3O /YCl2O byproducts and mitigates the irreversible phase transition of single crystal NCM811 (SCNCM811), thereby improving the compatibility between LYZC and SCNCM811.
