Abstract
The surface of particles was modified by a simple dry coating with as a coating agent. The -coated showed enhanced lithium-ion intercalation stability and thermal stability at and a high cutoff voltage of 4.5 V. Electrochemical impedance spectroscopy and transmission electron microscopy showed that the coating on the particles played a key role in stabilizing the interface between the cathode and the electrolyte.Keywords
