Abstract
A method of manufacturing a lithium secondary cell includes preparing an anode precursor and a cathode precursor by coating current collectors with electrode compositions, each not containing a plasticizer, preparing a separator precursor by coating both sides of a porous polymer film which is not gelled by an electrolytic solution with slurry containing an ion conductive polymer and the plasticizer, laminating the anode and cathode precursors and the separator precursor to prepare a cell precursor, and activating the cell precursor by injecting the electrolytic solution into the cell precursor. In the method of manufacturing method of the lithium secondary cell, the lithium secondary cell can be manufactured without a process of extracting a plasticizer using an organic solvent. Thus, environmental contamination due to plasticizer extraction can be prevented, thereby reducing the manufacturing cost of batteries.
