摘要： A pouch type lithium secondary battery may include an electrode assembly to which an electrode tab is attached; a pouch which includes an aluminum layer and a sealant layer and which encases the electrode assembly so that a portion of the electrode tab is exposed therefrom; a protrusion formed by sealant on a side of the pouch where the electrode tab is not exposed, in melting and flowing toward the electrode assembly then congealing to form a swelling on the pouch; and folds formed by bending a side of the pouch where the electrode tab is not exposed, wherein at least one of the folds includes the protrusion.

摘要： A method of mixing a cathode active material in a process of manufacturing a cathode of a lithium secondary battery is provided. The method includes a preparation step of preparing a lithium compound removal solution in which PAA (polyacrylic acid) is mixed with a solvent, a removal step of reacting the lithium compound removal solution with the cathode active material, on a surface of which a lithium compound is present, thus removing the lithium compound present on the surface of the cathode active material, and a mixing step of mixing the cathode active material, which is mixed with the lithium compound removal solution, with a conductive material and a binder.
