Abstract:
A cathode, a method of forming the cathode and a lithium battery including the cathode. The cathode includes a current collector and a cathode active material layer disposed on the current collector; the cathode active material layer includes a lithium transition metal oxide having a spinel structure, a conductive agent, and a binder; and at least a portion of a surface of the cathode active material layer is fluorinated.
