  "textContent": "A lithium secondary battery according to exemplary embodiments may include a cathode which includes: a cathode current collector, and a cathode active material layer formed on the cathode current collector and including cathode active material particles; and an anode disposed to face the cathode. The cathode active material particles may include activated over-lithiated oxide particles and a coating material formed on at least a portion of the surface of the activated particles and containing a coating element. An upper limit of operation voltage of the lithium secondary battery may be 4.5 V or less relative to the oxidation-reduction potential of lithium.",
