Formation of a glue‐nanofiller layer between grains, consisting of a middle‐temperature spinel‐like Li x CoO 2 phase, reinforces the strength of the incoherent interfacial binding between anisotropically oriented grains by enhancing the face‐to‐face adhesion strength. The cathode treated with the glue‐layer exhibits steady cycling performance at both room‐temperature and 60 °C. These results represent a step forward in advanced lithium‐ion batteries via simple cathode coating.
