Abstract
A method of preparing a lithium secondary battery is disclosed, the method including coating a coating layer-forming composition including an inorganic compound and an organic/inorganic bindable silane compound having a first reactive functional group on a substrate to form a separator including a coating layer; preparing an electrode including an active material and a binder having a second reactive functional group; stacking the electrode to contact the coating layer of the separator, and adding an electrolyte to the electrode and separator to prepare a lithium secondary battery; and heat-treating the lithium secondary battery to react the first reactive functional group with the second reactive functional group and form a chemical bond.
