Abstract
A La<sub>4</sub>NiLiO<sub>8</sub>-coated LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> cathode was synthesized by solid-phase sintering, with Ni ions from the host material involved in La<sub>4</sub>NiLiO<sub>8</sub> formation. This strengthened the bonding between the coating and host cathode, and improved the cathode's structural stability.
