Publication number: 20220407181Abstract: A method for manufacturing a separator for an electrochemical device which uses polyvinyl pyrrolidone (PVP) as a dispersing agent, and provides high dispersibility of particles and prevents aggregation of particles, even when inorganic particles having a small particle diameter is used in slurry for forming a porous coating layer. Therefore, the inorganic particles are distributed homogeneously in the porous coating layer of a finished separator. In addition, since PVP is used with a fluorinated binder resin, the separator shows improved peel strength and adhesion to an electrode. Further, a non-solvent ingredient for the fluorinated binder resin is used as a solvent for PVP, and a non-solvent ingredient for PVP is used as a solvent for the fluorinated binder resin.Type: ApplicationFiled: November 17, 2020Publication date: December 22, 2022Applicant: LG ENERGY SOLUTION, LTD.Inventors: Jin-Woo HEO, Hye-Jin KWON, Su-Jin YOON
