摘要

高效球磨实现均匀的BaTiO3涂层，而不牺牲离子电导率（1.06 mS cm−1）。铁电BTO涂层通过电场调制抑制了Li2.5Y0.5Zr0.5Cl6 （LYZC）在4.8 vv下的分解，在150次循环后保持了76%的容量。BTO有效地减少了zrcl30 /YCl2O界面副产物的形成，减轻了单晶NCM811 （SCNCM811）的不可逆相变，从而提高了LYZC与SCNCM811之间的相容性。

BaTiO3 Nanoparticle-Induced Interfacial Electric Field Optimization in Chloride Solid Electrolytes for 4.8 V All-Solid-State Lithium Batteries

Highlights

Time efficient ball milling achieves uniform BaTiO₃ ( coating without sacrificing ionic conductivity (1.06 mS cm⁻¹).
Ferroelectric BTO coating suppresses Li_2.5Y_0.5Zr_0.5Cl₆ (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.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
