摘要： As a polymerization solvent for use in the polymerization of monomers for a hydrocarbon-based electrolyte polymer, a mixed solvent containing a first solvent, such as dimethyl acetamide, N-methylpyrrolidone or dimethyl sulfoxide, and an alcohol as a second solvent is used instead of a dimethyl acetamide/toluene mixture or dimethyl acetamide alone according to the related art. By using the mixed solvent, it is possible to obtain a molecular weight of polymer equal to or higher than the molecular weight of polymer obtained from the method according to the related art, even when the reaction time is reduced. Therefore, the disclosed method and polymerization solvent is very useful for a mass production of a hydrocarbon-based electrolyte polymer.

摘要： Proposed are a method and apparatus for manufacturing a laminate film for a cell-type battery pouch. More specifically, the present disclosure relates to a technology of manufacturing a pouch film used to manufacture a pouch-type battery. Specifically, when manufacturing a laminate film for a pouch using a dry lamination process, induction heating rolls that are controllable in heat generation thereof are used to perform a post thermal treatment process after performing a lamination process using thermal rolls. The method and apparatus can reduce an aging period that is required to improve the physical properties of a manufactured pouch or can improve the physical properties of a manufactured pouch without an aging process.
