A “5V‐class” all‐solid‐state lithium battery (Li/Li 3.2 PO 3.8 N 0.2 /LiCr 0.05 Ni 0.45 Mn 1.5 O 4‐ δ ) demonstrates an improved rate capability when its electrolyte/cathode interface is modified by dielectric BaTiO 3 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.
