PURPOSE: A lithium secondary battery and a fabrication method of the same are provided to form a coating film having excellent spreadability on a cathode or an anode, thereby preventing internal short-cut and enhancing the safety of the battery. CONSTITUTION: A fabrication method of the lithium secondary battery comprises steps of: preparing an anode plate of lithium oxide, a cathode plate of carbon and a separator inserted between them; and coating a film on one side of the anode plate or the cathode plate. The film coating step comprises steps of: agitating polymer into organic solvent to dissolve it; preparing the polymer into slurry state; coating the slurry on the anode plate or the cathode plate; dipping the coated plate into different solvent; and drying the coating film. |
