Abstrakt: A “5V‐class” all‐solid‐state lithium battery (Li/Li3.2PO3.8N0.2/LiCr0.05Ni0.45Mn1.5O4‐δ) demonstrates an improved rate capability when its electrolyte/cathode interface is modified by dielectric BaTiO3 nanoparticles. Such “dielectric modification” is supposed to be able to resolve a Li+‐deficient layer at the interface, which has limited the charge‐transfer reactions rates. [ABSTRACT FROM AUTHOR]
