With the aim of investigating the deposition of Au/Pd core–shell nanoparticles (NPs) on cathode materials to decrease charge transfer resistance, Au/Pd core–shell NPs were successfully synthesized and deposited on LiFePO₄ coated with carbon (LiFePO₄/C) using ultrasound irradiation. Transmission electron microscopy observation confirmed that dispersed Au/Pd NPs with an average particle size of 7.2nm were deposited on LiFePO₄/C. An X-ray diffraction measurement evidenced a peak shifting from 38.2 to 39.1 upon calcination at 400 C in Ar atmosphere, which can be attributed to the phase transition of the Au/Pd NPs from core–shell to alloy.

随着阴极材料调查的Au /钯核-壳纳米颗粒（NP）的沉积，以减少电荷转移电阻的目的，金/钯核-壳纳米颗粒成功地合成和沉积在的LiFePO ₄涂覆有碳（的LiFePO ₄ / C ) 使用超声波照射。透射电子显微镜观察证实平均粒径为7.2nm的分散的Au/Pd NPs沉积在LiFePO ₄ /C上。X 射线衍射测量表明，在 Ar 气氛中在 400 C 下煅烧时，峰从 38.2 移至 39.1，这可归因于 Au/Pd NPs 从核-壳到合金的相变。
