Abstract
A coated cathode, a device including the coated cathode and methods for preparation thereof is provided. The coated cathode includes: an active material (10) for supplying and storing Li+ ions, an electrically conductive additive (12), and a coating (11), different from the active material (10), that coats surfaces of the active material (10), wherein the coating (11) comprises amorphous halogen-doped titanium oxide, and wherein the coating (11) has a thickness ranging from 1 to 20 nm.
Claims16
