摘要： A method of activating an electrode material is provided. The method includes adding an ion-conducting salt to an organic solvent to obtain a salt solution. An electrode material is introduced to the salt solution to obtain a reaction mixture by heat treating. The reaction mixture is heat treated at a temperature in a range of 50 to 70° C. for a period of time to surface coat the electrode material with an inorganic compound to obtain an activated electrode material. The ion-conducting salt may be a metal bis(fluorosulfony)imide, the metal being selected from a group consisting of Li, Na, K, Zn, Mg, Al, and Fe. The time period may be at least 4 hours and may be in a range of 8 to 24 hours. The inorganic compound coated on the electrode material may be LiF.
